We have a 1990 Dodge W350 4x4, 360 automatic. We have a 9' blade on it and noticed at higher speeds or higher RPM it heats up almost overheating! When popping the hood I noticed (Why there ran it ?) the smallest radiator i have seen. My question is will a 5.9 Cummings radiator (alot bigger) same years 88-93 or will a late model 94-98 fit. Electric fans really wont work this radiator is way to small (must have been a Dodge joke) Anyways some advise will be considered! Thank you.
