Hi guys,

Today I was driving our 350z it super hot weather... we had the air con on full and noticed the car wanted to over heat when we went up a steep hill. We pulled over and let the car cool down... drove pretty hard for 20mins home with the air conditioning switched off.... as soon as we put it back on the heat gauge started to rise again...

Has anyone else had this problem?

Thanks

 

Hey. Welcome.. The radiator fans are supposed to kick on when the AC is on full. Check and see if they are actually turning on.

 

car gets warm and then you still proceeded to drive it hard.....not very bright

And then drove it hard 20 min home. But its his car. Wonder if he has even been back

 

Yes, never really found the problem , it just fixed itself on mine. Every time triggered by AC, even had it once shoot up quick, the ambient temp gauge shot up. Had it happen going up long hills a couple times , high ambient with AC on.

Awww, i must've hit a nerve

 

maybe check your fan fuse? i would flush my coolant with that yellow funnel attached to your radiator cap that way you can see all the air escape if there is any. I've never experienced a temperature spike with the ac on or off and it gets 100+ here in the summers
