Heating AC and Engine Cooling

Check your owners manuel if you have one if not call your local parts store they can look it up for you.

could have a crack in it that is leaking under pressure

Steam may be coming out the air conditioning unit if the engine is overheating. The best thing to do would be to shut the vents before any hazardous fumes begin to come out.

It could be the pump clutch, its wiring, relay or its fuse. Also check the belt tension.

not with out some modification

No, you run the risk of destroying the motor.

Car seat heating works by using electrical heating elements. They are positioned in the bottom and back of the seat and receive power directly from the vehicle.

there are two types of freeze plugs. the first type is metal. Take a small cold chisel in the center of the plug make ahole with the chisel and pry it out. get a socket as big as the outsideof the new freezeplug and tap it into place with a hammer paying close attention not to push it into far. The other type is rubber. Pop out the old one put the rubber one inplace it takes 1/2 socket and tighten it down

There is not an AC relay on the Mercedes-Benz v280. Instead, the AC compressor uses (or is driven by) the serpentine belt.

i have found that about 95% of the time on fords after rebuilding the motor that you need to replace the radiator and that will solve your problem.

i get low 30's most of the time if i drive responsibly

A stuck open thermostat will cause a car to run cooler than needed. It will cause oil to sludge, a loss of gas mileage due to running rich and numerous other problems.

Regular air filters are in a housing box towards the front of the car and are simply an insert laid into the housing which protects the engine from dust and dirt from the air so that it can breathe better. Since the whole intake is housed and enclosed, it draws hot air from the engine bay to feed the engine it's oxygen.

Installing a cold air intake constitutes removing the whole housing assembly and unbolting it from the engine bay. It is replaced with a pipe connected directly to the throttle body that leads down by the driver's side wheel well. On the end is the air filter. This draws cooler air in from outside the engine bay. Cold air is favorable because it is more dense, which will help the combustion of the engine, in turn producing more power. The engine can breathe easier as well, in turn working less hard, which (in theory) gives you slightly better MPG.

BEWARE: Installing a CAI puts your engine at risk of hydrolock.

a piston has gone thru it or u have a bad freeze plug

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

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.

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.

Low refrigerant charge? Blown fuse?

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

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.

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.

it re releases the oxygen back into the atmosphere if it is burnt
