Fleece Performance 89-98 Dodge 2500/3500 5.9L 12V Cummins Replacement Heater Core Line Kit

Fleece Performance is known for making solid parts for Cummins engines, and this stainless steel heater core line kit is no exception. If you're working on a 1989-1993 Dodge D250 or D350 with the 5.9L 12V Cummins engine, this kit is designed to replace your old, potentially leaky heater core lines.

These lines are made from stainless steel, which is a strong material that resists corrosion much better than the original rubber or steel lines. This means you're less likely to deal with rust or leaks down the road, especially in areas where road salt is used. The kit is designed to fit right into your existing setup, making the replacement process straightforward for someone familiar with working on these trucks. Replacing these lines is a good idea when you're doing other cooling system work or if you notice any coolant leaks around the firewall.
