Car overheats with the A/C on....

[Kash$civ]

Car overheats with the ac on, replaced radiator and hoses etc. Worked fine for a while, then under really hot weather, the temp gauge goes up dramatically when the ac is put on. Im thinkin it might be the thermostat, but we just replaced it. so i dunno what it can be. No leaks of coolant anywhere...

I don't know what to tell you but probably by the next time you read this it will be moved to the tech section.

That sounds like an odd problem. Have you tried running it without the A/C to diagnose it?

Does it have coolant?
