Thermostat question??

[tattguy12]

Car runs fine but seems to start over heating when the air con is on it was bubbling like crazy last night? But when the air is off its fine? Any help would be great.

of course check the level in the radiator when cool, but check in
front of the radiator and A/C condensor for bugs, cotton ect.
you may have to either blow it out with air or a garden hose
sprayer from the engine side of the radiator.

Yep, I agree with Randy.  Blow out the cooling fins from the engine side of the radiator and the AC condenser.  Be careful not to flatten out the cooling fins with too much pressure or you'll exaggerate your problem.  Good luck!

I changed out the thermostat seemed fine for a week. Now its over heating without the air on??/Any help would be great.

 Have your cooling system pressure checked .  If that is fine , could be many things. Radiator cap, radaitor partially plugged or old and corroded at the fins , water pump , Faulty new thermostat, and electric fan not turning on .  Have you tried turning the heater on to help cool it down . If so does it help ?

What kind of car and what engine?
