Keep coolant flowing cleanly between the engine and heater core with the Dorman - OE Solutions HVAC Heater Hose Connector 800-401. This engine-to-heater connector installs as a direct-fit replacement for the listed GM applications, including the 1994-1996 Buick Century, 1990-1999 Chevrolet C1500, 1990-1995 Chevrolet Camaro, 1995-2000 Chevrolet Tahoe, and 1992-2000 GMC Yukon — see the Buyer's Guide tab for the full 66-application list.
What it does:
Engine-to-heater connection: joins the heater hose to the engine's coolant path, carrying coolant toward the heater core.
Direct-fit replacement: made to install on the listed applications in place of a cracked, corroded, or leaking original connector.
Targeted repair: if a failed connector is the source of coolant seepage at this junction, this part replaces it so the hose can seat and seal properly.
Diagnose the cause of any coolant loss before replacing, since leaks can originate elsewhere in the cooling system. Top off and bleed the cooling system after installation.
It's an engine-to-heater hose connector that joins the heater hose to the engine's coolant path, routing coolant toward the heater core through a secure, sealed connection.
What are the signs this connector may need replacing?
Coolant seepage or drips at the hose junction, visible cracking or corrosion on the connector, and repeated low-coolant conditions are common signs. Diagnose the source before replacing.
