C3 Tech Tip - Engine Getting Hot?
- Nov 5, 2013
C3 Corvettes are known for their cooling issues. Yes, you could replace the radiator, but this may not resolve your problem. You can inspect your fan shroud, fan blade, fan clutch and even radiator. All these items can cause problems, but they may not be the problem either. Inspect for good sealing around the radiator support to radiator, radiator to fan shroud seals, make sure the fan clutch is working properly and make certain the radiator is clean inside the vanes. The C3 changed the way you need to think about cooling. No longer is it a front air type cooling system, it now gets its air from underneath. All air is picked up off of the road, pushed up into the front of the radiator and then through. The one item everyone forgets is the spoiler. This was not put there for looks, it works! If the spoiler is not installed, air will pass under the car and never get pushed into the radiator, so the radiator will heat up and cause problems. It is a must to have either the original spoiler or an aftermarket spoiler in place to give you the air flow required to keep things cool.
