Heating AC and Engine Cooling
Heating, air conditioning (AC) and engine cooling require a radiator to transfer heat. Heating a cabin requires heat to be transferred from an engine block. Engine cooling blows the heat out of the engine. AC uses refrigerants to cool air.

Will Stop Leak clog up a heater coil and make it blow cold air?
Usually 'Stop Leak' will not clog the core. Try flushing the cooling system out first. Note: The hot water goes in and the cooler water comes out. Flush the core going the other way so to clear any obstructions. If there is a clog, it might be something larger like bits of hose or corrosion. If the core is totally clogged, take it out and replace it with a new one. The amount of time you will spend doing this does not warrant using an old or used core.
overheating could be caused by alot of things...OVERHEATING can damage the engine...get it checked or read up on how to... ...everyone should have a manual for their vehicle(parts store or dealer), and a local library should have professional shop manuals available in the REFERENCE section for free...make copies of the appropriate sections...read up and good luck :)
Where is the Coolant Temperature Sensor on a 2003 durango?
be carefull, there is a coolant temp sensor and an engine temp. sensor on a lot of engines, easily confused. if you d.i.y., get the specific book designated page of component location, best way to do it. also on any engine sensor replacement, purchase sensor at dealer due to exact calibration for ecm. some aftermarket replacements are a little off.
How do you replace the cabin air filter in a Chevrolet Impala?
what year?
1st: find the Wix part no. for your filter
2nd: go to: www.smartsynthetics.com/pdf/cabin_air_filters.pdf
3rd: Scroll down to the correct part no. & voila
4th: Enjoy a cold beer.
Oh Yes! A bad caliper so the piston cannot travel freely to allow brake pads to disengage or a brake caliper that simply "locks up" and puts big drag on brakes = lots friction = lot of heat
Why is only warm air blowing when heat is on full after putting in a new thermostat?
The first possibility is the thermostat didn't work. To find this out, after the engine is warmed up u check the hoses going from the engine to the heater, they should be hot. if they are hot then the next reason would be a cable to the temp on the heater needs to be adjusted or the heater core is plugged inside or out.
Car heater and defrost only blow cold air?
Thermostat stuck open, if older car possibly clogged heater core- when run at oper temp the hoses going into/out of heater core be sure one is very hot - start with thermostat $$$ cheap & easier than a heater core problem!
How much does it cost to get a new AC Accumulator?
I JUST BOUGHT ONE FROM NAPA IT WAS 18.88. BEST WAY TO FIND OUT THOSE KIND OF QUESTIONS IS TO JUST PICK UP THE PHONE AND CALL AN AUTOPARTS STORE
Where do you put water to cool the engine on a Volkswagen beetle?
It depends on the year of the car. Older beetles were air cooled and did not use any water.
check egr valve
Where do you find the fuse for the airconditioner on a 2006 Ford Taurus?
the relay is under the hood on the drivers side wheel well the fan fuse is under the dash on the drivers side
1994 dodge ram 2500 has no heat only blows cold?
Could be that the thermostat is stuck open, new thermostat fixed my 2001 Dodge 3500. If your temperature gauge is not reading warm enough, could be the thermostat.
How many miles per tank can you go on a 2009 civic ex gives?
That all depends on your driving habits. If you know approximately how much the tank holds and the approximate MPG's. you can figure it out.
What are the dangers of inhaling antifreeze?
The inhalation of the vapors of ethylene glycol can have a serious affect on the brain and nervous system, analogous to the way wood alcohol (methanol) can damage or destroy the optic nerve.
Where is the idler pulley located on a car?
Most idler pulley's are near the top and usually quite easy to get to. Press on the belt somewhere, enough to deflect it a couple inches and watch to see which pully is mounted on a tension spring. That is the idler pulley.
It could be any number of things, but I'd check for bad fan relay or fuse, sticking thermostat, blocked radiator or blown head gasket.
How do you disconnect heater core hoses?
Well what type and year of car is it? they are just clamped on at the firewall on the passengers side normally. If you need to disconnct it for a while so you can keep driving purchase a flush valve or drain vave at the parts store and connect the 2 ends of the hoses to it so as to make a loop.
Engine overheats When a car or truck overheats idling, in town, on the highway, while towing, etc. it is important to find out the reason to prevent engine damage. First, with the engine cold, make sure the radiator is full of coolant; if it is low, fill it and keep the radiator cap off while the engine idles to insure all air is bled out of the system ( air trapped in the system can cause overheating also). Check the coolant level daily; if the coolant goes down without visible leaks, it may be a head gasket starting to leak which will also cause the heater to blow cold air due to the lack of available coolant. If the coolant stays full, but the car continues to overheat, the next step is to replace the thermostat in the engine and flush the cooling system if that has not been done over the last few years.Buy a thermostat at a parts store and a PRESTONE flush kit which has excellent directions on the package.After completing these steps and the vehicle still overheats, have your cooling fan sensor/switch ( if equipped)checked out to insure it is coming on. Water pumps are seldom the cause as they are mechanical and will continue to work until their bearings give out. Finally, the radiator itself is often the problem as it tends to build up corrosion internally which prevents it from transfering engine heat to the coolant. Remove it and have it 're-cored'. One of these steps will solve the problem.
How do you convert r12 to 134?
The manual will say change all the flexible lines and O rings.
The truth is that you will need to remove the compressor and receiver tank.
Drain all the oil from the compressor, replace the receiver/dryer.
Insert new 134 compatible oil. Replace all disturbed O rings.
Charge with 134A .
Should work
Ac compressor wont take charge 134a you even jumped the ac clutch?
easy if you have put power to clutch from battery and system is in vacuum and centure of clutch is turning with the motor in means to say your valve plate is dead in side compressor.
How do you check a head gasket?
- Remove and check your spark plugs, a cylinder that is burning coolant will generally show perfectly clean while the others will show normal gasoline burn patterns
- Pressure test the cooling system, this will expose any leakage to the exterior of the engine
- There is a special chemical and tool that actually detects exhaust gasses as they exit the cooling system. Most radiator shops and large auto repair shops have the system. You will have to pay for this test.
Where is the location of the cooling fan relay switch on 2004 Montana?
There are 3 cooling fan relays located in the fuse box just above the battery, in the engine compartment. (passenger side, near the front of the car) You will have to take the fuse box cover off. The other side of the cover lists all relays. I think the radiator cooling fan motors are switched in series or in parallel depending on how much airflow is needed - hence the 3 relays.
Why won't the engine cooling fans come on in my Windstar?
This could be due to the following: 1. Check the fuse at the fuse panel for a blow. 2. Check the relay in the fuse panel. 3. Check the sensor 4. Bad wiring connection... 5. Defective fan...
How do you fix a 1992 Dodge Dakota that won't blow hot air on defrost but it will on vent?
It's okay we found out from trial and error. We just flushed the rad several times which removed all build up that was causing the problem. The heat works like brand new now.
