What kind of damage am I doing to the engine/turbo by running the car without the cooling fan? I just bought a 1991 mr2 turbo with a trunk mounted intercooler (with 2 fans attached) and when they removed the stock intercooler they removed the engine cooling fan too. I have no idea why they would do this but I wanted to know the negative effects of driving it this way. The warning light comes on (when the sensor realizes the temp is 140 degrees in the engine bay) but the coolant/engine temp gauge in the car nevers runs warm. The manual says to keep your speed under 37mph and go to the dealer. Some people have told me that it will be ok but the engine bay area will just be a little warmer than normal. Thanks for the help.
Actually, the engine bay fan is for the side mount intercooler. There is a sensor on the underside of the engine lid which controls the fan. With the sensor plugged in, you will never see the fan come on. If you unplug the sensor, the fan will run as long as the key is in the ON position.
As long as you have fans on your IC, you should be OK.
^ Yeah , you can always install a fan where the stock IC used to be or on the engine lid.
But like I said, with the engine at idle, you will not see the fan kick in.
Sounds good. Thanks for the help fellas. I will sleep a little easier tonight knowing that. I appreciate you all taking the time to answer my questions.
I wonder how the intercooler gets enough cold air in an enclosed (and carpeted) trunk even with 2 fans attached? Underneath the intercooler he cut out the floorboard but the factory exhaust is right underneath the opening. It seems way to warm in that small enclosed space and fresh/forced cool air never gets to the intercooler.

Good question.
There should be inlet and oulet for the air to flow. Lots of guys do a trunk mount IC, but they make sure that there is sufficient airflow.
Have you made a thorough inspection of the trunk?
Maybe there's some venting somewhere you mighta missed?
If you don't find one,it would be beneficial to make one.
I will check it out in more detail in the morning. Thanks again for your help. I don't think he has any areas open for ventilation (other than the opening in the floorboard just above the exhaust). When I open the trunk the intercooler and both the pipes are VERY warm to the touch. The whole trunk is hot for the most part. It seems to me that the dual fans are just pumping the enclosed hot air to the intercooler. I guess I'm going to have to vent the trunk lid itself. I even thought about just taking the trunk lid off on nice weather days until I can find a fix. It will look a little wierd but I don't care.
That makes sense. I think I'm just going to try and make the current setup work more effecient until I decide how much money to throw into it. Thanks again for the help.
