How to Flush a Car Engine Heater CoreOn a periodic basis, a car's heater core has to be flushed in order to rid it of the debris and dirt that builds up within it over months of daily use. Avoid doing this, and you could encounter problems with your heater core over time. As this is not a job which requires a high level of mechanical knowledge, most car owners should be able to perform it themselves. If done properly, it should not take more than an hour to complete. What tools and equipment do I need to flush my heater core? There are several tools you will need to flush your heater core: Pliers and screwdriver Use these to help you loosen the hose clamps. Collector pan Catch the old coolant and detritus flushed out of the heater core with this. Garden hose Ideal to help flush the heater core. Second hose This will direct the flow of water exiting the heater core during the flushing process. Why do I need to flush my heater core? The heater core is comprised of the core itself, which features two valves connected to the radiator via "in" and "out" hoses, which are clamped in place. These hoses allow water to enter, circulate and drain out of the heater core back into the radiator. They therefore need to be removed so water can flushed through the core. If this is not How to flush a heater core in 10 simple steps After you have gained access to the heater core by removing the dashboard, remove the clamp on the "in" hose using the pliers and screwdriver. Different car models will vary in terms of the process here - you should consult your vehicle's handbook if you are not sure. Do the same for the "out" hose. Attach the garden hose to the "in" side and position the collector pan under the "out" side to catch the used coolant that will leak out. You may wish to attach a second length of hose to the "out" side in order to better direct the coolant into the pan. Run the water through the core until it runs clear. The length of time taken here will vary depending on the amount of build-up in the core. Switch the hose to the "out" side and run the water through in the opposite direction to ensure that everything has been caught and flushed out. Once you are satisfied that the heater core has been thoroughly and completely flushed out, reattach the "in" and "out" hoses by re-clamping them in position. Turn on the engine to start reintroducing coolant to the core. It should naturally begin to circulate again. If you experience leaking within the cabin or the heating does not work, this may mean that something's gone wrong and a mechanic may need to be consulted. You may then wish to top up coolant levels to replace any that was lost during the process. As far as mechanical know-how is concerned, the only difficulty you might have will be detaching and attaching the hoses with the clamps. The rest of the task, however, will be straightforward and easily achievable for everyone from novices to experts - while you can ask a garage to do it for you, it's much cheaper to do it yourself.
Heater Core Problem?
Refer to my answer in "how do I bleed a radiator" You need to bleed the cooling system as a whole. Meaning, car at operating temp with thermostat open (both top and bottom radiator hoses will be hot indicating coolant blow through thermostat). Open bleed using radiator key until you have fluid flow and air is gone. Check for additional bleeder nipple on thermostat housing and bleed (using same method as radiator) if present.

If you tick all those boxes, you are good to go. Run it on 95% oil and 5% conventional diesel in summer and a 60% oil and 40% diesel mix in winter.I have driven several vehicles fuelled on cooking oil.

Fix the heater on my Ford Explorer?If you do not have any coolant leaking inside or outside the truck then it's a very simple problem to fix..and should not cost you alot of money if you can do it yourself ..just change your thermostat..the reason it is working sometimes and not on other times is because it's sticking open. .if it sticks open then the coolant can not warm up..so it is allways running cold..the way a thermostat works is that once your car gets to a certain temperature ."usually on the thermostat" then it opens up and starts to cool the motor and in turn warming up the liquid. .get yourself a good all season thermostat usually for a ford truck would be 190-205 degrees..if you want to change it yourself should be simple just follow the big hose from your rad to the engine and you will see a metal housing held on with 2 nuts..remove these two nuts and remove the old thermostat and replace it with a new one . ."in the same position" you may need a new gasket as well..or you can use RTV silicone..i would get a new gasket for a few dollars6. Name of water heater part?Pilot light7. can the water pressure valve from heater cause an explosion(pics) (10 points) ?The valve with red handle is probably the inlet water valve. Open the valve completely. What controls the amount of water entering the heater is the amount you are using at the lavatory to brush your teeth. You have a faucet on the lavatory that you adjust for the amount of water you need. The valve with the red handle should be full open so that it gives you all it can. Now, on you heater, you also have a pressure relief valve that is screwed directly into the side of the hot water tank. And there might be some piping that would carry that discharge away from the tank. That line does not have any valves, restrictions or anything that would interrupt the emergency discharge of steam from the tank. I do not see the pressure relief valve in the photo

The second type are more efficient, but the valves which control the water flow are also inclined to get clogged up.How do I know if my heater core is clogged?
How Many Labor Hours Listed to Replace Heater Core on 03 Buick Century V6 and Is It a Knuckle Scrapi

Personally I think most heater cores are a pain to replace but for me I've found a do it yourself auto wreckers helps me alot bec it offeres the chance to actually learn just how a certain dash etc comes a part hands on. On my car for example its a Intrepid , I had to take a part 3 different Intrepids dashs just to even find one really good heater core. But to be safe I had it pressured tested and tested over night to make sure it was in fact a good heater core for 15.00.It turned out it was the best used heatcore the wreckers I took the heat core to have tested that they had ever seen. I knew the job wou;d be a real pain bec of the experience taking a few out so I looked around and waited till I found a cheap garage father son that did it for me as I was on vacation and the weather was getting coller and I had no time to do it myself. They said they would never do one again unless paid triple lol was in fact I was right to let someonelse to the job lol Only problem was I knew they would crack something or forget to connect something or mess something up.

Hope that helps and best of luck , by the way do not forget to reconnect the radio, antenna etc lol1. I have a '95 Nissan Maxima. Can I flush my heater core without going through too much hassle?I own a shop, and can tell you this; If you will go to a parts store and purchase a flush valve that you install in the heater hose, you can hook a garden hose to it, open the drain on the radiator, and turn on the hose full blast while it is running, and this should flush the whole system pretty good. They are pretty cheap, easy to install, and real easy to use. When you are done, you just turn off the valve and leave it installed in the hose for the next time you wish to flush the system. Cut the hose, install it with two clamps that are provided, and you are good to go. Part 2: I would think a master technician would know that bolts are not measured by what size wrench fits them. They are measured by the (outside diameter) OD of the bolt, and (inside diameter) ID of a nut. The other measurments are; length, threads per inch or (mm) millimeter, hardness, and type of head used on the bolt, as in Hex Head, Socket Head, or whatever it may be.

Sputtering Sedan Could Have a Stuck Valve
QUESTION: I have a problem with my 2005 Nissan Altima. My "check engine" light came on, so I went to the mechanic to have him pull the code. He said it wasn't really reading anything, reset the code and told me to come in if it happens again. The next day it came on again. I stopped at the gas station since I needed gas and filled my tank. When I went to start my car, it wouldn't start. I sat there for 15 minutes before it started. When it did start, I had to give it some gas because it was sputtering. The "check engine" light was still on so I brought the car to the mechanic the next day. He reset the code again and said to let him know if it came on again at the gas station next time.I filled up about a week later, and once again it wouldn't start. I told my mechanic this and he said to try to get gas with the car running next time. So once again, I got gas but this time left my car running.This time, as I was pumping gas, the car was sputtering and the tachometer was fluttering the entire time. But when I was done pumping, it seemed to run just fine. My car acts up only when filling gas; otherwise it runs great.R.S.ANSWER: What's interesting about this question is that the mechanic is trying to pinpoint the problem by asking the car owner to do all the work! Try this, try that, etc. Since the "check engine" light has come on each time, a scan tool should identify the specific DTC fault code associated with this problem. The comment "wasn't really reading anything" doesn't make sense - the "check engine" light was on!I suspect the DTC will relate to the evaporative emissions system, which includes the purge valve. If the purge valve is stuck open, raw fuel/vapours can be pumped through the charcoal canister directly into the induction system during refuelling, which, of course, would create exactly the symptoms you've described.Q: I have a 2004 5.7-litre Dodge Durango with 260,000 kilometres. As I come to a complete stop, the tachometer will drop momentarily from around 750 r.p.m to less than 500. The engine will occasionally stall. I must depress the gas pedal slightly to get it restarted. Initially, I had the throttle body thoroughly cleaned, then replaced it this past weekend. I also replaced the oxygen sensors, but nothing has helped. I should also mention that the "check engine" light has never come on. Any ideas?K.D.A: The 5.7-litre V-8 in this vehicle is equipped with a "flyby-wire" throttle system. Instead of a mechanical cable or linkage connecting the throttle pedal to the throttle body, an accelerator pedal position sensor, or APPS, is fitted directly to the throttle pedal and electrically connected to the powertrain control module, or PCM. In simple terms, rather than the throttle plate being opened and closed mechanically by movement of the throttle pedal, the position of the throttle pedal is communicated to the PCM, which operates the throttle via signal to the electronic throttle body.Now that you've cleaned and replaced the throttle body, which includes the throttle and idle air control valve, I'd suggest plugging in a scan tool and having the APPS swept/checked for dead spots in its potentiometer. Also, check for any type of vacuum or air leak in the induction system that would allow unmetered air into the system.Q: I have a 1998 Chevy S-10 and I am getting the smell of antifreeze coming from the air vents. It seems to be stronger when the heat is on. There is no antifreeze leaking anywhere in the engine or under the dash. The heater core hoses are tight, and they are both hot after warming up the engine. I just recently bought the truck and a short time after that the A/C quit working. I don't know if that would cause the smell to occur. I would hate to replace the heater core if I am not sure that that is the problem. Any advice you can give would be greatly appreciated.R.G.A: Your thoughts about the odour coming from the heater core are well founded, as this is the only area within the truck cab where antifreeze exists. It's possible also, but less likely, that leaking coolant odours are coming in with the ventilation air from an under-hood leak.Typically, when a heater core begins to leak, one may notice fogging of the windshield when using the defroster; damp-slimy carpet beneath the right/centre of the instrument panel; and a citrus-like odour, similar to what you've described. There would also be a loss of engine coolant, but the rate may be less than you'd expect - it only takes half a litre of leakage to create the above symptoms - and this might not be immediately evident looking at the coolant overflow bottle level. A leak from under the hood should be easy to spot on the ground.Your heater core is a cigar box-sized mini-radiator that transfers engine heat to the passenger compartment via circulating engine coolant. This part resides deep within the heater/ventilation system, and most aren't very pleasant to renew, as quite a bit of instrument panel disassembly is often required. Most heater cores are made of thin-wall aluminum, with a large network of finned passages that provide maximum surface area for heat transfer. Over time, accelerated by deferred cooling system maintenance, internal corrosion will find a weak spot, and pressurized coolant will begin to seep into the surrounding housing, and eventually to the carpet beneath.I have a hunch your heater core may have a tiny leak, and most of the liquid may be vaporizing, causing the odour, or hasn't yet reached a seam of the heater housing. To be sure, you may need to drill a small hole in the lowest part of the plastic housing. Slide a piece of hose or tubing on the drill bit so it can't bore more than one-quarter inch deep - you don't want to cause new problems. Then, after shutting off the fully warmed up engine and waiting perhaps 15 minutes, check for signs of coolant leakage at the test location. Even one drop of coolant means trouble.I can't fathom how the air conditioning working or not would be a factor regarding this odour. Refrigerant is odorless, should leakage occur. It's likely a coincidence the A/C has recently quit.Paul Brand, author of "How to Repair Your Car," is an automotive troubleshooter, driving instructor and former race-car driver.

1985 Mustang Heater Core?
Why would someone bypass a new heater core? I replaced a heater core in an 83 mustang with A/C years ago. It took 2.5 days to strip the car's dash all the way down and then replace it.

If the car does not have A/C, the job is much easier.1. what is wrong with my AC/Heater?it sounds like you have a bad fan switch. in the furnace area you will probably see a part with a silver/chrome cover that you should be able to put in manual or auto. more than likely that needs replaced assuming your fan just runs all the time. common problem ps to pull the wires on that there are little tabs you depress2. What is wrong with my car heater?Whatever is controlling your cool/hot blend door is malfunctioning, or the door is sticking3. How to Clean Thermocouple on Water Heater?Do you have colder showers than you would like, or is the water you use for dishwashing feel lukewarm? Knowing how to clean thermocouple on water heater can help you bring back more enjoyable showers, more efficient dishwashing, and others. The thermocouple is an essential element of your gas water heater's pilot light, ensuring more efficient water temperature management. Unfortunately, it can rust or wear out over time. There is no need to replace your thermocouple when all you need are a bit of elbow grease, a few tools, and this step-by-step guide to breathing life back into your thermocouple. Things You Need to Clean Your Water Heater's Thermocouple Cleaning your gas water heater's thermocouple is a pretty straightforward activity. However, there are a few preparations to get the job done. While open-end wrenches may suffice, you may have a whole bunch of these tools on hand if you do not know the size of the different nuts in your system. An adjustable wrench eliminates the need for several devices and makes your work more efficient. Emery cloth is almost similar to a nail file which has an abrasive surface. The difference is that an emery cloth has a fabric backing, while an emery board or nail file has a wooden base. The function is similar, nevertheless. They sand or smoothen the thermocouple ends while also removing oxidized layers. This type of cleaning cloth is ideal as a finishing touch to the thermocouple cleaning process. Its main advantage is that it will not leave any fluff on the surface. We recommend a microfiber cloth for cleaning the thermocouple. While not necessary, a small brush can help dust off particles from the thermocouple and the burner assembly. If the emery cloth cannot remove stubborn stains, you can use a steel pool. Always look after your safety when working with your gas water heater. Turn off the gas supply to your unit. If your unit has a power cord, it would also be best to unplug it. Some gas water heaters have two gas supply valves: one going to the gas furnace and another to the water heater. It would be safer to turn both valves off. Pro Tip: If your gas supply valve does not have a lever or a knob, you can use a pair of pliers or a vise grip to shut off the valve. If your burner has an access cover, unthread the mounting screws first. Loosen and remove the screws or nuts that secure the burner plate. Loosen the nut that connects the burner supply line to the control center. You will also disconnect the pilot light supply tube and the thermocouple. If your unit has any wires connected to the control center, you must disconnect these, too. Check your tank base if it has a vapor sensor. Detach the sensor if you have one. To gain access to the thermocouple, slide the burner assembly out of the water heater. Pro Tip: If this is your first time removing the burner assembly, it would be best to take a picture of it before disassembly. The image serves as a guide for you to reassemble the unit after cleaning the thermocouple. Sand the thermocouple ends using an emery cloth. Some plumbers recommend using steel wool to remove stubborn stains on the thermocouple. Ensure you do not see any dirt, soot, or residue after cleaning. Check the area between the thermocouple terminal and the power wire for any sign of corrosion. Remove the rust if any. Finish cleaning by wiping the thermocouple ends with a clean microfiber cloth or any other type of lint-free cloth. Pro Tip: Avoid using so-called thermocouple cleaning solutions, regardless of how convenient they may seem. Some of these products may contain flammable chemicals that can pose a threat to your system and your home. Do not limit your cleaning duties to the thermocouple. Now is the best time to give the burner a thorough cleaning as well. Get your steel wool or emery cloth sandpaper to scrape as much stain as possible from the burner's top. Use a small brush to remove debris that might go into the burner ports or holes. Cleaning your burner will improve your gas water heater's efficiency. Return the burner assembly into the water tank. Make sure to rest the burner tube on the bracket for security and stability. Secure the burner plate by threading and tightening the mounting screws or nuts. If your unit has a vapor sensor, reattach it first before reconnecting the different wires to the water heater gas valve. Position the thermocouple to the gas valve and secure it. Reconnect the pilot light supply line and the burner gas supply tube to the control center or gas valve. Replace and secure the water heater burner access cover. Open your water heater's gas supply line and plug the power cord of your unit if it has one. Turn on the pilot light and adjust the thermostat to your desired temperature. It would be best to dial in a temperature not higher than 120 degrees Fahrenheit. Check your water if it is in your desired temperature. Do you think our simplified guide on how to clean thermocouple on water heater is simple and easy to follow? There can be many reasons why your water heater is not producing hot-enough water. A dirty thermocouple is one of them, but one that many people overlook. Now that you know how to clean your gas water heater's thermocouple, you may want to share this knowledge with your friends.

What happens if heater core fails?When using the heater you may experience foggy windows accompanied by the sweet aroma of the coolant inside the car if it is leaking. If it gets worse it will leak into the heater box and into the carpet of the car. Make sure that if there is a control valve to let the coolant flow that it is working by checking to see if the hoses are hot. I had a plymouth car that had issue with the core clogging up slowly over time. Every couple of months a visit to the carwash was done and heater hoses were pulled off and the pressure wand inserted into the neck and blasted out the crud. It worked like a charm. I would think you may not be able to as easily reach the heater core in most new cars but, disconnecting the hoses where they meet the engine and blasting through it with a garden hose nozzle might work. If the core is leaking it must be taken out to be fixed as in replaced and yes they seem to be deliberately designed to make it a real pain to service. The core may only cost $100 but the labor will be much, much more2. how to change the heater core out?I am going to be brutally honest with you. If you are not very good mechanically.

A room heater and a humidifier?I can not figure out why anyone would think it is dangerous. You would want to put as much space as possible between the two so they are not neutralizing each other.

Community Wiki Or Canonical Dup for No Heat
The problem with that answer is that it is a very specific fix to that particular vehicle. We can't expect to forward everyone that as answer.Different problems need to be treated differently.That said, it would be nice to have a comprehensive list of common causesI've seen two questions in two days with regard to blowing cold air. One has to do with when the car is at idle, the other has no conditions.Heater blows cold at idle 2007 town / countryHeater only blowing cold airIs it possible to come up with a canonical duplicate for questions like this? It seems reasonable to be able to put together a finite set of conditions and troubleshooting flowchart that incorporates most common causes.I found one answer that was an exception to the standard set of possible causes in a quick search: Seems like the "my heater is cold" question comes up often enough -- especially this time of year -- that we could generate something. It might not make sense to mark questions as a dup, but it certainly would be nice to (at the very least) throw a CW link at them in a comment.EDITI answered a question a while back regarding how the heater core works; it's a subset of the broader question as to why heat might not be present: EDIT 2Paulster2 said: Something else to think about with this, isn't this what the site itself is supposed to accomplish? If the answers are out there, we point them to them in the first place and close the new question as a dupe. If tags are done correctly, it's fairly easy to find answers if they are out there.I think you've effective hit the meat of my question -- do we have an answer enough that has enough solid content that we can build on it? Is the OP okay with converting it into a CW?
