I installed a FMIC on my car a few month ago. Now when the temperatures are beginning to ger real warm in Sweden (around 30-35 degres) I must use the AC in the car. When I drive the car for a while with the AC on the engine temp meter begins to rise. Is that a common problem due to the FMIC? Does anyone here have the same problem?

The car is a STI MY05.

When you switch on the air con your radiator fans should come on to keep the air con gas condenser cool. Check that is happening.
It is not abnormal to see a small temperature rise with the use of air con but not a big rise.
What are the figures?
