overheating but AC seems fine

[marjoon]

the coolant gets very hot and the car is overheating

i dont have any problems with my AC yet so i dont know what is the cause of this situation.

The AC has nothing to do with the cooling of the engine, it is only used to cool the inside of the car.

if the car is over-heating it may be due to the radiator fan not working. or maybe a radiator leak? have you had a look to see if there is enough water in the radiator? have you had a look at the coolant level?

another issue might be a faulty thermostat; in which case the car is perfectly fine, but the thermostat is taking a "hot" reading

Better check the radiator both hoses by hand and see if they are very very hot and hard then that means your car is actually overheating and gauge is showing you the right readings. If not it could be bad water temp sensor, its cheap fix.

If car actually overheating then check all the fans (Engine and AC fan) and then check the radiator isn't clogged, thermostat is open and closing at right temp, in last you can doubt water pump pressure is adequate to circulate water or not.

If thermostat is bad then one of the radiator hose will be warm and soft and other will be damn hot, that means coolant is staying longer in engine jacket as thermostat isn't opening at right temperature.
