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.

changing the valve cover gasket will not fix an over heating problem u need to check out the cooling system. Radiator, water pump, hoses, belts
an aircooled engine is an engine that is cooled by air.
most cars now a days are cooled by water.
aircooled engines include but are not limited to-
old style vws and porches
some airplane engine
some motorcycle engines
Why does car heats up when ac is on?
The car seats because of the extra energy it needs for the AC compressor work
Most likely this is a blocked drain hose from the HVAC system. When it can't drip out condensation fast enough, the water contacts the AC evaporator and causes a foggy mist.
How do you replace a cabin air filter on a 1998 Chevrolet Z71?
supposibly there is a kick panel under the dash there are four bolts holding it on after getting it off there is one more bolt which is the cabin filter housing take it out and pull down on the panel there are two filters in there you pull the first one straight down the the next one you will have to pull sideways then down however i have a 1999 model and is the same body style as the 1998 and i can't seem to find one on it my kick panel doesn't come out as easy as most that iv seen.
How do i replace a thermostat for a 1998 Chevrolet Cavalier?
2.2L OHV Engines * Drain coolant (about 1 gallon) from the radiator until its below the thermostat housing * Disconnect the radiator hose from the thermostat cover * Remove the bolts and lift the cover off you mat have to tap the cover with a soft-face hammer to loosen it * Not how its installed then remove the thermostat 2.3L and 2.4L OHC Engines * Drain the coolant from the radiator * Remove the exhaust manifold heat shield * Remove the cover that protects the outlet pipe on the thermostat housing by accessing cover bolts through the exhaust manifold runners * Raise and secure the car on jackstands * Disconnect the radiator hose from the metal outlet pipe * Remove the outlet pipe bolt and carefully separate the outlet pipe from the thermostat housing and the engine block * Note how its installed then remove the thermostat from the outlet pipe
Have you driven a Ford lately?
Anyways, if this is a Ford you probably have a blend door actuator problem or a cracked blend door. This can get expensive. If you read your owners manual (and most people don't) you would not have this problem.
If it's a GM (especially with dual-zone climate control) you might have a software problem that can be corrected by disconnecting the battery for ten minutes or by installing updated computer software.
If you have something else, it is not a problem that I have seen often. Please specify vehicle. Its a 99 GMC Jimmy S10 blazer. I agree that its probley the blend door acuator. I am having diffeculty locating it so I can test it. I ahvent been to the library yet to lookit up. Thanks for your input Dan
Why does cooling fan not come on when car starts to get hot?
Check all fuses.
Check the fan motor. Unplug it and connect wires from the battery directly to the motor. If it doesn't spin then it's broken.
Check the cooling fan relay. Many relays have a wiring diagram printed on the side to make it easy to test.
Check the temperature sensor. Compare voltage to manufacturer's specification. On some vehicles, you can read this voltage at the computer using a scan tool.
Check the wiring. A cut or burned wire can cause an open circuit.
What happens when head gasket blows?
Antifreeze will leak into the oil & things such as but not limited to: Car overheats, can crack cylinder heads and/or cause worse damage all the way to complete engine failure. Stop driving asap & inspect the oil dipstick for a brownish color in the oil and or water bubbles present.
Why does ac compressor clutch engage and disengage?
Usually, on most cars, this means that the weather is cool or that there is insufficient refrigerant in the system. It can also be caused by a restriction in the AC system or high temperature or excessive amount of refrigerant in the system.
Car running hot and no heat inside what is the reason?
the engine is conducting the power to move the car and use oil and gas, while that is hapening, friction is also occoring at the same time therfore causing heat to be exerted. Low or no coolant. Also. if coolant is low on antifreeze, the coolant will freeze and not circulate, causing the engine to run hot while blowing cold air through the heater fan.
If the condenser motor runs but the compressor will not run what would check in most cases?
check to see if your lowon freon
Most engines get around 400 degrees. However the paint rated for 1200 degrees will be able to block the heat.
First you have to know what cool is. Then you market - by communicating cool messages. If cool is sunglasses and a leather jacket, you sell cars by showing them with some dude in sun glasses and a leather jacket. Cool man! First you have to know what cool is.

What is the function of a radiator fan relay?
The reason for any relay is to have lower power to the control circuit. If you tried to run the fan directly from the electronic control module there would be either insufficient power to run the fan or you would damage the ECM by drawing too much power and overheating it.
What are the symptoms of a bad coolant temperature sensor on a 91 corsica?
Yes. There are less chemicals in organic skin care products than non-organic and therefore is better for your skin. http://www.organicsanonymous.com/
What does a head gasket look like?
picture rectangular shaped gasket, if 3 cylinders on each head each gasket has 3 circles representing cylinders and thin gasket maybe half inch wide between each circle then bolt holes for head bolts too

If you are saying that at highway speeds it is running at 40 degrees celcius (and it isn't extremely cold out), I would say that your thermostat is sticking open. I know you put a new one in, but every now and again a new thermostat will either stick open or shut. If you do the work yourself, what you can do to test the thermostat is to remove it and put it in a pot of boiling water, you should see it open up. Now remove it from the water and watch it, it should close up in a short amount of time, if it doesn't you need a new thermostat. If it is working, I suggest making sure that the cooling system is completely full with no air in the system. If this doesn't work, you might want an expert to take a look at it. Hayden
Either the radiator is partially plugged and t he system has been designed marginally ( they do that to save money you know ! ) so that when the heater is turned on most of the water gets routed through the heater core, bypassing the radiator and causing overheating, or the system is just designed marginally and as above. You can put your hand on the radiator grille and feel it from the front of the car ( using all due caution, of course ) and see if there are any sudden temperature changes from hot to cold. A cold spot indicates a plugged section. The only solution to this is to replace the radiator. And/or you can also put a restriction in the line feeding the heater core, so that more water will flow through the radiator. If your car has worked well in the past with the heater turned on, then I would suspect a partially plugged radiator. I've changed these myself, and it's not hard. Make sure you don't have any other systems bonded to the radiator for cooling, like power steering, a/c , etc. Good Luck !!
Why is gas in the oil reservoir of Briggs and straton air cooled engine?
The engine is flooding or the spark plug is fouled and not burning all the fuel, allowing the excess gas to seep into the oil reservoir via the piston cylinder. Cleaning or changinge the spark plug and doing a carburetor adjustment will help.
How does motor oil cool a car engine?
Some engines actually have a separate oil cooler [I'm not talking about the transmission oil cooler] for cooling the crankcase oil. and some, like the Jaguar, have heavy cast aluminum oil pans with fins, designed to dissipate heat from the oil.
I agree that the radiator system is designed for and does the bulk of the cooling, but the motor oil circulation system does contribute by distributing and disipating some of the heat.j3h.
