The 5 Best 1 inch Heater Hoses (2023 reviews)

It has all the quality features of a regular coolant hose for interchangeable use. It fits both bypass and heater hose application, engine to pipe trim to fit. This is a small short hose running from the rear of the water pump to the intake manifold, right at the bottom of the thermostat housing. It comes with a protective sleeve to help duplicate gm design for proper fit and function.

These are composed of specially blended materials to help reduce hose failure. It is a good quality hose for bypass as-is or can be trimmed for heater (engine to pipe) application. They don't last forever (can stick) and you will have your coolant drained to do the hoses.
