Gates Molded Heater Hose for Scion tC

The Gates 19414 molded heater hose is an OEM-style coolant hose built for tight engine compartments where a formed routing path is required. It is made from EPDM and measures 23.8 inches centerline length with 0.66-inch inside diameter ends for a precise replacement fit.

Compatible with 2005-2010 Scion tC heater lower applications, this molded hose supports coolant, water, and air transfer and is also approved for marine use. Gates Molded Heater Hose products are shaped to follow factory routing, helping maintain proper hose alignment in compact underhood layouts.

Detailed Description

This molded heater hose is built for the lower heater circuit on the 2005-2010 Scion tC and is shaped to match the tighter packaging found in modern engine bays. The Gates 19414 uses a molded profile rather than a straight universal hose, which helps it follow the original routing path and maintain a cleaner installation. If you are replacing a worn or leaking Scion tC heater hose, this OE-style replacement provides the correct formed layout for the application.

This part cross-references Quality-Built 11414 for the same application.

What It Helps Fix

• Coolant leaks from a cracked or aged heater hose
• Softening, swelling, or collapse in the lower heater hose
• Improper hose routing in a tight engine compartment
• Loss of heater circuit flow caused by hose deterioration
• Service replacement for a damaged molded coolant hose

Installation Notes and Tips

Verify end diameters, centerline length, and molded shape against the original hose before installation. Confirm routing on the 2005-2010 Scion tC heater lower position and inspect adjoining clamps, fittings, and coolant condition during service. Proper hose alignment is important in compact engine bays to avoid kinks or contact with nearby components.

Gates manufactures this molded heater hose as an OE-style replacement using EPDM material and factory-molded dimensions for the listed application. Part number 19414 is built to match the original hose form for the 2005-2010 Scion tC heater lower position.
