Detailed Description

Gates 19582 is a molded HVAC heater hose designed to match the original hose path on 2009-2012 Toyota RAV4 models at the heater outlet. Its pre-formed shape helps maintain proper routing in smaller, tighter-fitting engine compartments, reducing the need to force a universal hose into place. If you are replacing a worn or leaking Toyota RAV4 heater hose, this molded replacement supports a direct, OE-style service approach.

This part cross-references Dayco 87951 for the same application. The Gates 19582 molded heater hose is a practical choice when you need the correct hose diameter, length, and bend profile for a clean cooling-system repair on the Toyota RAV4.

Common Problems This Hose Can Address

• Coolant leakage at the heater outlet hose
• Cracked or hardened EPDM hose material
• Poor routing from a universal hose in a tight engine compartment
• Restricted heater hose flow caused by a damaged or collapsed hose
• Incorrect hose shape during a Toyota RAV4 heater hose replacement

Installation Notes and Tips

Verify hose routing against the original part before installation. Confirm both ends measure 0.63 in. (16 mm) and check that the 20.5 in. (521 mm) centerline length matches the vehicle layout. Inspect adjoining heater pipes, clamps, and coolant connections for wear or corrosion before installing the new hose.

For best results, install on a cool engine and refill the cooling system with the correct coolant after service. On 2009-2012 Toyota RAV4 heater outlet repairs, proper routing is important to avoid kinks and maintain consistent coolant flow.
