Intercooler Causing Overheating, Solutions?
The other day I was mounting up my intercooler to test the fitment. I decided to leave the intercooler mounted up to see how engine temperature was when I drove around. Engine temperature stayed between 160 and 220. Which is a lot higher than it is without the intercooler. I have a manual fan swith that I never used until now. How can I fix this heating problem? How can I make it so the radiator gets more cooler air? Do you guys with intercoolers have engine heat problems then? I just bought a new radiator less than a year ago with out any heating issues until now.

I removed the fog lights to let more air through. I was thinking of using some some flex tubing to force more air to the radiator somehow.

Re: Intercooler Causing Overheating, Solutions?
It was a 90 degree day yesterday and it went up to 220 briefly when i was cruising at 25 mph. The fans kick in automatically around 160-190 degrees. I am not sure about the thermostat. Whatever is in there, it is stock. Normally my car temp would be at 100-130 degrees when I drive around even during the summer months last year. Then now it sits at 160-180 when I drive normally.

Re: Intercooler Causing Overheating, Solutions?
Did you leave a gap between the IC and the airdam? I left an inch on mine and its working fine. Getting air to the radiator via the airdamn is critical on our cars.

I think that could be the problem with me. I just checked and the intercooler is about 1/4 inch away from the air dam.

Re: Intercooler Causing Overheating, Solutions?
I don't see any problems with your car. A 195 stat will make the car run upwards of 220.

I fixed the problem. I made the gap between the air dam and the intercooler to more than an inch. The larger gap helped, so thanks for the help.

Re: Intercooler Causing Overheating, Solutions?
Well if it ever bothers you again, get an aftermarket temp gauge, and a 160* stat. Maybe an aluminum rad.
Your car warmed up a lot higher than 130*...unless you run methanol as a fuel.

Re: Intercooler Causing Overheating, Solutions?
I have the exact same intercooler, and in the exact same place...lol... I have a new aluminum rad that is narrower but about three times thicker then factory and I don't have any problems keeping it cool.
