Heating AC and Engine Cooling

The 1998 Toyota Rav 4 cooling fan relay diagram can be obtained from most Toyota dealerships. The diagram can also be found in most repair manuals.

1997 VW Jetta GL's dont have them... There is an air intake but no compartment for a filter. Sad but true.

Its always best to cycle the a/c compressor on and off several times in any weather condition so that the small amount of oil will travel around the system but there is a small chance of locking the compressor up as well if its not done............

In the engine compartment, in the service box on the passenger fender.

Como seira fan related

In a fuse box under hood

This is a question?

So now ya don't even try to ask da question, we also need to find da question?

Maybe the cooling is caused by a decrease of the temperature, who knows.

Is that in °C or °F? may help to answer.

The water pump moves the coolant around the system so the heat can be transferred inside.

When air conditioning or front defroster are turned on it will turn on A/C compressor which requires the A/C condensor to be cooled (via radiator fan).

Not sure what you really mean but if temp of heat does not change = likely bad thermostat etc. If gauge does not work at all but heat is fine then gauge or electrical type problem to the gauge

Look for bleeder valve about 1 1/2 inches tall somewhere usually front corner of engine when facing it, open small valve on top & bleed with engine at normal oper temp - usually need to open & bleed & repeat process to bleed

what are we talking about therma gasket? or thermostat gasket and for what veh or unit?,.what is your concern a llittle more info please

first of all let me state that if your coolant was not mixed according with your state climate we'll that's how your rad froze there are only two things you can do,..1st thing is to run hot water on top of your rad ,..2nd is to stall block heater to your engine and 3rd id to mix your coolant accordingly so it won't freeze again

Possible that coolant is leaking into combustion chamber and burning off. Does engine act like its missing at idle and smooths out at higher rpms? possible head gasket. I had the same problem i used steelseal.com worth its weight in gold.

You have to heat the windscreen in order to make the water dissolve into the air again.

When the screen gets too cold, the air directly around it inside the car will also be cooled. The maximum degree of humidity of air depends on its temperature, and the cooler it gets, the less water it is able to contain. Therefore water that can not dissolve in the air will condensate - on your screen. Heat it up and it will dissolve again.

bad temperature sensor

Home freon and R-12 freon for vehicles (yes) but not R134a freon which you can get at any autozone..................

Hell To The Yeah no i don't think slavery is cool as all the human beings have their own rights no one is supposed to be working for other except in need of money

too cool for school.

most likely it's a bad thermostat, or your vents not working properly.

The only thing that I've heard of with "wet cooling" in, is a wet cooling tower. A Wet Cooling tower for the closed-circuit cooling of water where the water to be cooled comes into direct contact with the cooling air dissipating heat by evaporation and air heating. The air draught required for cooling can be induced by fans or by the natural effect of the stack of the cooling tower building (natural draught cooling tower).

So I don't know if that answers your question or not, but i hope it helps...
