I am the third owner of a 1986 corvette. I was probing around my vette today and realized i have two fans on my radiator. To my knowledge i thought there was only one fan on the 86 model. But there is an electric fan on the front of the radiator. Is this aftermarket?

 

On my 89 the front fan isfor the oil cooler.

 

yes thank you very much. I started reading more and found out its a RPO KC4 engine oil cooler
