Check your fans first.

Does the temp climb above normal under load? eg driving wot?

CS3 was doing something similar last year. would overheat under load. regardless of A/C on or off though.

Turned out some of the tubes in the radiator were clogged with sediment. Problem never recurred after a good cleanout of the cooling system.

Thinking teh same thing, that's why i asked.

Had a similar problem recently, going over the LYR temp would skyrocket going uphill, goes back to normal once going downhill.

Solution, don't laugh.


Drained rad, disconnected top and bottom hoses, blocked off with plastic bag and tie straps.
Flushed with clean water, then refilled with Toilet bowl cleaner
Came in a gallon bottle, active ingredient *something* acid.

Let sit for a few hours and then drained, placed garden hose in filer neck and let flush, got large chunks of rust and deposits, looked like flake fish food.

Rad looked polished inside after, no more problems.

active "acid" ingredient in an aluminium rad overnight? that could be recipe for a shutdown.

Im still trying to work out why OP's problem is worse when the AC is on though. As if his A/C switch restricting fans from going into the higher speed.

There's a radiator flush tablet that dissolves any scale and build up, good to clean a really dirty rad. @ RS - yuh eh easy. Toilet bowl cleaner?

Nah just a few hours.

Tried conventional flushes, didn't work.
What really caused my problem was using a bottle of radiator stop leak on an already dirty rad.
