Fleece Performance 98.5-02 Dodge 5.9L Cummins VP Coolant Bypass Kit

Take your Cummins engine to the next level with the Fleece Performance Coolant Bypass Kit. Designed to address the shortcomings of the factory cooling system, this kit ensures consistent temperatures across all six cylinders, even at high horsepower levels.

The Cummins engine cooling system was designed to cool a 300-350hp engine, but when you increase the horsepower, the demand on the cooling system increases too. The rear cylinders suffer from a lack of coolant flow, leading to excessive pressure and potentially catastrophic failures. Our kit solves this problem with a secondary thermostat that works based on temperature, not excessive pressure.

• High-quality AN o-ring fittings and AN hose connections with braided hose for a leak-free installation
• Secondary thermostat ensures consistent temperatures across all six cylinders
• Designed to address the shortcomings of the factory cooling system
