ok so when i drive with my ac on my car overheats when i come to a stop and when i drive without it, it is fine anyone have any clue to what this could be?

 

Mine does this too, but I'm boosted, and I think my problem is the Thermostat, not 100% sure though.

 

does it only happen when at a stop? check to see if the condenser fan works

 

yes it does and i have changed my thermostat twice already thinking it was that and yeah it does only happen at a stop and i just changed my condenser fan

 

It's possible that the condenser pulley is bad, or the AC belt is too tight. If there's too much strain on the engine when the AC is turned on and your stopped, it could cause an excessive production of heat as the engine works harder, if the engines working hard, you should be moving, but if it's working hard while stopped, the cooling system may not be able to compensate for the extra heat produced without the rush of cold air your radiator see's while driving. Just an idea, but I hope this helps!

 

ok kool i will have to check that thank you

 

bleed the cooling system

 

how do i bleed a cooling system?

 

take the radiator cap off, fill up the radiator and run the car for 15 minutes with the cap off.. if the coolant fluid in the rad. lowers top it off

 

Yup, if you have air pockets in your cooling system it could cause an overheating problem. and your sure your fan is working correctly? You said it was switching on but I mean your sure it's comming on with the full amount of power it needs? Water pump is working? Radiator cap is releaving pressure when it's supposed to??

 

Does the radiator fan run when the engine is hot?
