your cooling fan(s) is/are not working your cooling fan(s) is/are not working
Your car can only create cold air if the engine is running to make the coolant work correctly. If your car is idle, your engine is still hot but your engine isn't running so the air you are receiving is actually air heated by the engine.
Why does my transmisson only slip whe it is hot but runs well when cold
No, as long as the engine is not running hot it will not bother the transmission.
Over heating (running to hot), Fast idle (Incorrect idle adjustment), Incorrect timing, Carbon build up in combustion chamber,
I found out what the problem was - the idle air controller
the 84 uses an idle air control valve to control idle speed. this is a function done by the computer. if the idle is too low when cold but runs ok when hot, or ok when cold but then too high when hot, then chances are your idle air control valve is bad. if the idle is high all the time, you probably have your pcv valve vacuum line disconnected. if your brakes seem very hard to push as well, then it's probably your brake booster vacuum line. if neither of those, look for other vacuum hoses that may be disconnected. there is no user adjustable idle speed control for that car.
When the car is at idle, the air conditioner works just as hard as when the car is moving. When the car moves, the engine gets very hot. so the air conditioning works better when your at idle because it doesn't have to cool the heat from the engine.
They say that the minimum oil pressure at idle (600) rpm on that engine is 13 pounds. I have the same engine in my cj5, and it has 60 at idle on start up, and only 4 pounds at idle when hot. It still runs good though. It has 276,000 miles. Those motors are bullet proof!
Depending on the car and the year many current vehicles run for a few seconds at fast idle even on hot start to activate the pollution control devices in the exhaust system
Car Runs Good in Cooler wheather but when hot outside it runs for about a miniute then dies.can you please check your car's Cooling system for proper operation, such as radiator fan comes on, rotation of the fan is correct and radiator is not blocked etc?
your car ac will only blow hot air when there coolannt in the car is finished or the car is oveerheated.
Your car climate control is only hot or cold because these are the two most common options. When it is cold out, the heater is ran and when it is hot out, the air conditioner helps make the car cooler.
