Good To Know

Q: Will this kit work with my stock cooling system? A: It is designed to work alongside the factory coolant routing on the listed Dodge Ram and Cummins engines. Confirm your engine year and displacement before ordering.

Q: Do I need to drain the cooling system to install it? A: Yes, the cooling system should be drained before fitting the bypass lines. Refill and bleed the system afterward to remove air pockets.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
