Fleece Performance VP Coolant Bypass Kit for 1998-2002 Dodge Ram 2500/3500 (5.9L / 6.7L)
$379.00
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits 1998-2002 Dodge Ram 2500 and 3500 (5.9L / 6.7L).
The rear cylinders on the 5.9L and 6.7L Cummins engines often suffer from restricted coolant flow, leading to localized hot spots and excessive pressure buildup at the back of the block. This thermal stress can result in catastrophic failure, including blown external freeze plugs or the smaller diameter plugs located under the valve cover. The Fleece Performance VP Coolant Bypass Kit addresses this design flaw by integrating a secondary thermostat that operates based on coolant temperature rather than just pressure. This ensures consistent cooling across all six cylinders and relieves the pressure before it reaches critical levels.
- Regulates coolant temperature at the rear cylinders to improve engine longevity
- Secondary thermostat design ensures cooling based on temperature for consistent performance
- Prevents damaging pressure buildup that leads to freeze plug failure
- High-quality braided hose with AN O-ring fittings for a secure, leak-free seal
- Complete installation kit specifically designed for VP-series Cummins applications
- Manufacturer Part Number: FPE-CLNTBYPS-CUMMINS-VP
