Gates 23048 Radiator Coolant Hose - Lower

Gates 23048 Molded Coolant Hose

The Gates 23048 molded coolant hose is a radiator coolant hose built to OEM-quality specifications for select Toyota applications. It is formed to match the routing needed for lower coolant service on Toyota Hilux and Toyota Tacoma models, helping restore proper coolant flow and hose fitment.

Gates Molded Coolant Hose products are part of a broad replacement line covering upper, lower, bypass, heater, and other coolant hose applications. This molded design is made from EPDM for durability in cooling-system service and is shaped for direct replacement use where a formed hose is required.

Detailed Description

Gates 23048 is a molded radiator coolant hose engineered for lower hose applications on 2005-2015 Toyota Tacoma and 2005-2015 Toyota Hilux models, with fitment varying by year. The formed shape helps match the original routing path, while the EPDM material is suited for cooling-system temperatures and coolant exposure. If you are replacing a worn Toyota Tacoma lower radiator hose or a Toyota Hilux lower coolant hose, this part provides the correct molded configuration for the listed applications.

This part cross-references Bosch 62674 for the same application.

Common Problems This Hose Can Address

• Coolant leaks from a cracked or aged lower radiator hose
• Softening, swelling, or collapse of the original hose
• Poor hose routing after an incorrect replacement part
• Cooling-system service needs on Toyota Hilux and Toyota Tacoma models
• Loss of coolant flow caused by a damaged molded hose

Installation Notes and Tips

• Verify year-specific fitment before ordering, since Toyota Hilux and Toyota Tacoma coverage varies by model year.
• Inspect hose clamps, necks, and adjoining cooling-system components before installation.
• Drain coolant safely and refill the system according to the vehicle service procedure.
• Confirm the molded hose follows the original routing without twisting or kinking.
