Gates 19430 HVAC Heater Hose - Inverter Cooling Hose-2

Gates 19430 Molded Heater Hose Overview

The Gates 19430 molded heater hose is an OEM-style coolant hose built for tight engine compartments where a straight hose will not route correctly. Made from EPDM and factory-molded to the proper shape, it supports coolant, water, and air transfer and is also approved for marine applications.

Compatible With 2006-2010 Toyota Highlander inverter cooling hose-2 and 2006-2008 Lexus RX400h inverter cooling hose-2, this molded hose helps maintain the correct routing and fit for the vehicle’s cooling system. The Gates Molded Heater Hose line focuses on formed replacement hoses that match the original layout for specific applications.

Detailed Description

Gates 19430 is a molded HVAC heater hose built to follow the original hose path in applications with limited clearance. Its EPDM material is suited for coolant circulation and other fluid or air transfer needs, while the molded construction helps preserve the correct bend and routing in the engine compartment. This part cross-references Quality-Built 11430 for the same application.

For Toyota Highlander and Lexus RX400h models, the formed profile supports proper installation where the inverter cooling hose-2 location requires an OE-style shape rather than a universal hose. The 29.8-inch centerline length and 17 mm ends provide the dimensions needed for a direct replacement in the listed vehicles.

Common Problems This Hose Can Address

• Cracked or leaking inverter cooling hose
• Collapsed hose routing in tight engine spaces
• Improper hose fit after previous repairs
• Coolant seepage at the hose connection points
• Restricted flow caused by a damaged molded hose

Installation Notes and Tips

Verify the hose path, end diameters, and centerline length before installation. This molded hose is specific to the inverter cooling hose-2 position on the listed Toyota Highlander and Lexus RX400h applications, so confirm routing against the original part before removal. Inspect adjoining clamps, fittings, and mating surfaces for wear or corrosion before installing the replacement hose.

Quality Assurance

Gates is known for OE-style hose construction and application-specific fitment. Part number 19430 is built as a molded replacement hose for the listed vehicle applications and follows the dimensions needed for proper routing in compact engine compartments.
