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

The Fleece Performance 98.5-02 Dodge 5.9L Cummins VP Coolant Bypass Kit is a high-quality cooling system upgrade designed to improve coolant flow and reduce temperatures across all cylinders. This kit features a secondary thermostat that operates based on temperature rather than pressure, effectively preventing excessive pressure buildup and ensuring consistent coolant temperatures. Constructed with braided hoses and AN O-ring fittings, it guarantees a leak-free installation. The inclusion of billet hose brackets in models for MY 2003+ enhances durability and installation ease. This bypass kit addresses common coolant flow issues in the 5.9/6.7L Cummins engines, helping to prevent freeze plug blowouts and potential engine failures caused by overheating and pressure buildup.

Designed for 1998.5 to 2002 Dodge Ram trucks equipped with the 5.9L Cummins engine, this coolant bypass kit is a vital upgrade for improving engine reliability and longevity. It is particularly beneficial for high-performance, towing, or daily driving applications where consistent cooling is critical. The kit is a direct replacement, easy to install, and eliminates the factory transmission fluid heat exchanger in the '03-'07 5.9L automatic transmission models, which is unnecessary outside cold climates. Suitable for use in various driving conditions, this complete kit enhances cooling efficiency, reduces the risk of freeze plug failures, and ensures optimal engine operation under demanding conditions.
