engine temp rises

[allentot]

ok here i go again... my engines temperature starts rising when i turn on the a/c..what could be the problem? but when its off the temp is well..and i just noticed that everytime i turned the a/c on the temp rises above normal but when i turned it off it goes down again to its normal temp??

The temp will rise a bit because the air coming through the AC radiator in front of the engine radiator, will be hotter.

The only other issue may be if the electric cooling fans for the AC are wired back to front,
ie:trying to suck the air towards the front of the car instead of blowing air into the engine bay.

Just a thought..

Cheers.

could also be that he engine has to work a little harder when the a/c is on.. but thats a big maybe
