I wrecked the front end of my 97 Dakota and smashed the oil cooling unit and the radiator. Changed radiator and its still overheating and losing oil pressure. This is in turn causing spark knock. Is it due to the oil cooler? Help me please.

Oil cooler? Huh?

Dunno but my Dak.. has a Tranny cooler and power stearing cooling built into the Rad.. no oil cooling on her.

You prolly wanna post your truck info.. Motor size.. and all that.
