What is the primary function of this heater hose?

This molded heater hose connects your vehicle's heater control valve to the heater core. Its main job is to allow hot coolant to flow to the heater core, which then transfers heat into your cabin for warmth.

Why is a molded heater hose better than a universal one?

A molded hose is pre-shaped to match the original factory routing. This means it fits precisely without kinking or needing to be forced, making installation easier and ensuring a more reliable connection compared to a universal hose.

What material is this hose made from?

The hose is constructed from heat-resistant synthetic rubber. This material is chosen to withstand the high temperatures of the engine coolant and ensure a long service life.

Product Details

This is a Gates molded heater hose, part number 18908, designed to connect your vehicle's heater control valve to the heater core. It's specifically shaped to fit a range of Chevrolet and GMC vans from the mid-80s to the mid-90s, including models like the Chevrolet G10, G20, G30, and their GMC counterparts such as the G1500, G2500, and G3500. Proper coolant flow through the heater core is essential for getting warm air into your cabin, especially during colder months.

Gates uses a well-built construction with heat-resistant synthetic rubber to handle the constant flow of hot coolant. The molded shape means it follows the factory routing precisely, making installation straightforward without needing to bend or force a universal hose. This hose is built to withstand the temperatures and pressures found in your cooling system, ensuring it won't kink or crack prematurely.

When replacing your heater hoses, it's a good idea to check the condition of the other heater hose and the heater control valve itself. Having the correct, pre-formed hose like this one makes the job much simpler and helps ensure a leak-free connection.
