Heater Craft Hose and Fitting Kit
The Heater Craft H401 supplies heater hose and connection hardware for plumbing a compatible engine-coolant cabin-heater circuit.
Key Features
- 25 feet of 5/8-inch heater hose.
- Includes hose clamps and pipe fittings.
Installation Notes
Check the engine's approved coolant connection points and required thread sizes before installation. Work on a cooled, depressurized system. Route the hose away from sharp edges and moving parts, avoid kinks, then bleed and leak-check the circuit as directed by the engine and heater instructions.
