Fleece Performance 94-98 12V Coolant Bypass Kit

The Fleece Performance 94-98 12V Coolant Bypass Kit is a cutting-edge solution designed to enhance the cooling efficiency of your 5.9/6.7L Cummins engine. This comprehensive kit includes a secondary thermostat and a stainless steel braided line, ensuring increased coolant flow and reduced temperatures. Engineered to address the common issue of insufficient coolant flow to the rear cylinders, this bypass kit is a vital upgrade for any Cummins owner looking to maximize performance and reliability.

Key Features and Specifications

The Fleece Coolant Bypass Kit boasts several key features that set it apart from other brands. It features a secondary thermostat that operates based on temperature, not pressure, preventing damaging coolant pressure build-up. The kit includes a braided hose and AN O-ring fittings for a leak-free installation, ensuring a durable and long-lasting solution. Additionally, kits for model years 2003 and up come with billet hose brackets for added strength and stability.

Benefits and Practical Applications

Investing in the Fleece Coolant Bypass Kit offers a multitude of benefits for Cummins engine owners. By lowering coolant temperatures at the rear cylinders and ensuring consistent temperatures across all six cylinders, this kit prevents potential catastrophic failures, such as blowouts of freeze plugs due to over-temperature or over-pressure conditions. The kit is particularly useful for those in warm climates or high-performance applications, where the transmission fluid heat exchanger may be unnecessary or detrimental to performance. With the Fleece Coolant Bypass, you can enjoy improved reliability, longevity, and overall performance of your Cummins engine.
