The Cummins 3934373 kit is fantastic. Installed it on my truck, and it keeps the engine at the perfect temperature. Improved performance!

Product fitment issue, Excellent customer service
Fitment issue with My vintage 95 12valve Cummins. Customer Service always answered my calls and promptly rectified the situation. KLM will be my 1st stop for any needs of the products they offer! Rare thing these days that you even get a call back let alone someone that cares! Shop them, they’re a class act!
