Description
The Fleece FPE‑CLNTBYPS‑MAN Coolant Bypass Kit addresses the common issue of inadequate coolant flow to the rear cylinders in 2003–2007 Dodge Ram 5.9 L Cummins trucks with manual transmission. As engines are upgraded, the factory cooling system often struggles to manage the additional heat, leading to pressure buildup and potential freeze plug failures. This kit features a temperature-activated secondary thermostat that ensures consistent cooling across all six cylinders before pressure becomes problematic. It includes high-quality O‑ring fittings and AN hose connections, offered with your choice of braided black nylon or braided stainless steel hose for a secure, leak-free installation.
Features:
- Head removal not required for installation
- Includes temperature-activated secondary thermostat
- Ensures consistent coolant temperature across all cylinders
- Available with braided black nylon or braided stainless steel hose
- Backed by a 1‑year limited parts warranty
