Sinister Diesel - EGR Coolers for Cummins

EGR Coolers & Components for Cummins - EGR Coolers for Cummins
Your original factory Cummins EGR cooler is a critical component that helps keep your engine’s emissions under control, but weak construction and stress from high temperatures can often make your stock unit a liability. A failing EGR Cooler will leak coolant into your exhaust causing white smoke and poor running. At the most extreme, you can even see hydro-lock as coolant pools in the cylinders!

If you’ve had a problem like unexplained coolant loss, white smoke from your tailpipe, or a gurgling and spewing coolant tank, replace your Cummins EGR cooler before it becomes a bigger problem.
