Dtomi Engine Heater Hose Set for 3.6L GM Vehicles (Enclave/Acadia/Traverse) — Direct-Fit Pair

Dtomi engine heater hose set replaces both inlet and outlet bypass hoses for 3.6L Chevy, Buick, GMC and Saturn models, providing a direct-fit rubber assembly to restore coolant circulation.

These two front-position heater hoses are manufactured from durable rubber and are designed to match factory fit and function for select 3.6L GM vehicles. Supplied as a pair, the assemblies replace part numbers 20765678, 25862087, 25862088, and 626-562 so you can swap them in without modifying the cooling system. The hoses are intended to route coolant around the engine heater core and expansion tank area, helping maintain proper operating temperature when installed correctly.
