Swap out a cracked or leaking plastic original with the Dorman HVAC heater hose connector 800-403HP, an OE FIX metal replacement for the heater-to-engine hose connection. It fits many vehicles, among them the 1997-2000 Ford F-150, 1986-1989 Ford F-250 and 2000-2006 Chevrolet Tahoe, plus a wide range of other Ford, GM and Saab models. See the Buyer's Guide tab for the full list and engine details.
Heat and abrasion can make the factory plastic connector brittle. It can then crack, leak and break free from the heater hose, and the dealership solution is a similar plastic replacement. This Dorman heater hose fitting is made from rugged metal instead. It is designed to match the performance of the factory design while helping provide a longer-lasting repair.
- Upgraded repair: Rugged metal construction, designed to help provide a longer-lasting repair than the original plastic connector.
- Built to resist cracking: Engineered to resist the heat and abrasion that can eventually cause a plastic heater hose connector to crack and fail.
- Direct replacement: Made to precise standards for a seamless fit on specified Ford, GM and Saab vehicles.
- Pressure-tested: The upgraded connector design has been rigorously pressure-tested for reliable performance.
Size: 5/8 x 5/8. Position: heater to engine.
If a cracked, brittle or loose connector is the source of a coolant leak at the heater hose, this Dorman hose connector replaces it.
