Gates 00-04 Volkswagen Jetta V-6 2.8L Upper - Tee To Thermostat Molded Coolant Hose

This is a Gates molded coolant hose, part number 21203, designed to connect the tee to the thermostat housing on a range of vehicles, including the 2000-2004 Volkswagen Jetta with the V-6 2.8L engine. Coolant hoses are critical for keeping your engine running at the right temperature by circulating coolant from the radiator to the engine and back. Over time, these rubber parts can crack, swell, or become brittle, leading to leaks and potential overheating.

Gates uses a durable rubber compound for this hose, built to withstand the high temperatures and pressures found in a cooling system. Its molded shape means it follows the factory routing precisely, making installation straightforward without needing to bend or force the hose into place. This direct fit design helps ensure a secure connection and prevents kinks that could restrict coolant flow.
