Gates 96-05 Chevrolet Astro V-6 4.3L Heater To Valve (Top) Molded Heater Hose

If you're working on your 1996-2005 Chevrolet Astro with the V-6 4.3L engine, this molded heater hose from Gates is the correct part to replace the connection between your heater core and the heater control valve. A cracked or leaking heater hose can quickly lead to a cabin full of steam and a significant loss of engine coolant, so replacing it with a well-built hose is important for keeping your heating system working properly.

Gates uses a strong, heat-resistant rubber compound for this hose, designed to withstand the temperatures and pressures found in your vehicle's cooling system. Its molded shape means it follows the factory routing precisely, making installation straightforward without needing to fight a stiff, universal hose. This ensures a clean look and proper fit, preventing kinks or stress points that could lead to premature failure. This hose is specifically made for the top connection to the heater valve.
