Sinister Diesel - Oil Cooler

Engine Parts and Performance - Oil Cooler
The factory diesel oil cooler on your Cummins, Powerstroke or Duramax diesel is often a weak point in your cooling system. The small passages inside many diesel oil coolers can easily become clogged with particulates or scale in your coolant. This can choke the flow of coolant and lead to plenty of other problems like failed EGR coolers, loss of coolant, or even a blown head gasket. Sure you could just replace it with another stock unit, but that only pushes the problem down the road.

Upgrade Your Diesel Oil Cooler

Don't wait until your truck has oil cooler problems to do something about the stock unit. With Sinister Diesel, you can upgrade your stock engine oil cooler to allow for increased oil flow and more efficient cooling when your engine needs it most.
