Detailed Description
Gates 12429 is a molded HVAC heater hose designed around a 0.75-inch inside diameter at both ends and a 29-inch centerline length. The molded shape helps match original hose routing in compact spaces, making it a practical replacement when a straight hose will not follow the factory path. In Chevrolet Bolt EV applications, this part is listed for 2020 Bolt EV pipe to power inverter and 2017-2019 Bolt EV generator to pipe locations.
This part cross-references Monroe Shocks & Struts (e.g., 42540518, F12053) for the same application.
What It Helps Address
- Cracked or deteriorated heater hose routing
- Coolant leaks at molded hose sections
- Poor fit from non-molded replacement hose
- Routing issues in tight engine compartments
- Service needs for coolant, water, or air transfer lines
Installation Notes
Verify hose routing, end diameters, and centerline length before installation. This molded hose is intended to follow the original path, so correct orientation matters during replacement. Confirm the listed Chevrolet Bolt EV application and connection points before ordering.
Quality Assurance
Gates manufactures this hose as an OEM-style molded replacement under the Molded Heater Hose line, with EPDM construction and marine application approval.
