Fleece Performance 94-98 Dodge 5.9L Cummins 12V Coolant Bypass Kit

Fleece Performance is known for making parts that solve common issues, especially for Cummins engines. This coolant bypass kit is one of those parts, designed to help your 1994-1998 Dodge Ram 2500 or 3500 with the 5.9L 12V engine run cooler. The stock cooling system was originally designed for engines with lower horsepower ratings, and when you add more power, the cooling system can struggle to keep up. This kit helps address that by rerouting coolant flow to better manage heat.

The kit works by creating a bypass loop that allows coolant to flow through the block more effectively, helping to remove hot spots and improve overall heat transfer. This can lead to more consistent engine temperatures, especially under load or when the engine is working harder. It's a well-built solution that directly addresses a known limitation in the original cooling system design for these popular trucks.

Installing this kit can make a notable difference in how your engine manages heat, particularly if you've modified your truck or frequently tow heavy loads. It's a practical upgrade for owners looking to ensure their 5.9L 12V Cummins stays within optimal temperature ranges.
