Keep consistent coolant temperature to all 6 cylinders in your 2003-2005 Dodge 5.9L Cummins with an automatic transmission by installing a Fleece FPE-CLNTBYPS-CUMMIINS-0305 Coolant Bypass Kit. The factory cooling system handles the job of keeping a stock engine running at optimal temperature. Once performance modifications are introduce, the additional heat generated by turbo, fuel, and tuning upgrades can quickly overwhelm the cooling system. The rear cylinders begin to suffer from a lack of coolant flow, experiencing higher coolant temperatures and the buildup of excessive pressure in the cooling system. This can cause the freeze plugs to blow out or the smaller diameter plugs under the valve cover to fail.
