Features, Description, Q&A, Specs & Installation
Simplified Cooling System Upgrade. The Transmission Heat Exchanger Bypass Plug Kit is the ideal solution for modifying the factory cooling system on your 2003 to 2007 5.9L RAM 3500. This kit is specifically designed to bypass the transmission heat exchanger mounted on the driver side of the engine, which is necessary when installing an aftermarket coolant bypass kit. It streamlines coolant flow and helps improve engine cooling efficiency during performance upgrades.
Construction and Appearance. This kit includes a precision-machined M16 O-ring plug for sealing the engine block and two durable line caps to block off the heat exchanger hoses. All components are built to withstand high temperatures and pressure, ensuring leak-free performance during long-term use. The design maintains a clean, professional underhood appearance while supporting more efficient coolant routing.
Installation. Installation is simple and requires only basic hand tools. It's a direct-fit solution for performance cooling upgrades and integrates easily with most aftermarket coolant bypass kits.
Application. This Transmission Heat Exchanger Bypass Plug Kit fits 2003 to 2007 RAM 3500 models equipped with the 5.9L Cummins engine.
