Coolant Plumbing
During the engine conversion where you install a Caterpillar, Cummins, or Detroit Diesel engine in a heavy-duty truck, the installation often misaligns coolant ports, thermostat housings, and routing paths with your truck's factory cooling package—resulting in improper flow, leaks, and overheating. Kustom Truck Parts offers conversion-specific coolant plumbing solutions to ensure reliable, efficient coolant delivery in Kenworth, Peterbilt, Freightliner, and Western Star chassis.
Our lineup includes:
- Complete chassis heater hose plumbing kits
- Bulk replacement silicone heater hose
- Coolant shunt tube
- Stainless braided hose kits for Cat-specific applications
- Coolant distribution manifolds and supporting fittings
Built with durable stainless steel braiding and high-quality silicone for corrosion resistance and flexibility, these components solve routing mismatches without universal compromises—delivering proper flow, temperature control, and long-term reliability in demanding repowers or engine conversion projects.
