Detailed Description

This molded HVAC heater hose is built for vehicles that need a formed hose path between the valve and engine or between the tee and engine. It fits 1995-2004 Toyota Tacoma, valve to engine, and 1996-2002 Toyota 4Runner in valve to engine and tee-1 to engine positions, including 4Runner applications with an auxiliary heater. If you are searching for a molded heater hose for Toyota Tacoma or a heater hose for 1996-2002 Toyota 4Runner auxiliary heater routing, Gates 19129 matches those confirmed applications.

The hose’s molded design supports cleaner routing in compact engine compartments, while the EPDM material is suited to heat and fluid exposure common in HVAC and cooling circuits. This part cross-references Continental 64282 for the same application.

Common Uses

• Replacing a cracked or leaking heater hose in the coolant circuit
• Restoring proper hose routing in a tight engine compartment
• Addressing coolant loss at the valve-to-engine or tee-to-engine connection
• Repairing a hose that no longer holds its molded shape
• Servicing Toyota Tacoma and Toyota 4Runner heater hose routing

Installation Notes

Verify end diameters, centerline length, and routing before installation. Confirm whether the vehicle uses the valve-to-engine or tee-1-to-engine position, and check 4Runner auxiliary heater configuration where applicable. Gates 19129 should be matched to the original hose path to avoid kinks, tension, or misalignment.
