Product Details

Gates 24020 is part of the Straight Coolant Hose (Standard) line, a product family focused on straight hose routing where molded bends are not required. The EPDM material and 2-ply build support use in coolant transfer and other straight connection points across automotive and industrial systems. This hose is commonly selected for repair work where the original hose section is straight and the installer needs to trim to the required length.

This part cross-references Dayco 76125 and Four Seasons 24020 for the same application. It is also listed for a wide range of vehicles, including Toyota Prius, Lexus CT200h, and Chevrolet HHR, making Gates 24020 a useful replacement when the OE-style straight hose dimension matches the vehicle routing.

Common Uses

• Replacing a straight radiator coolant hose with the correct inside diameter
• Restoring coolant flow at upper rear or lower engine-to-pipe hose locations
• Repairing a cut-to-length hose section on Toyota Prius and Lexus CT200h applications
• Addressing leaks, cracks, or soft spots in an aging coolant hose
• Replacing a hose section where a molded hose is not required

Installation Notes and Tips

Measure the existing hose path before cutting, and confirm the required length against the vehicle-specific fitment notes. This hose is listed for multiple cut-to-length applications, including Fits 2010-2017 Toyota Prius, upper rear; Fits 2011-2017 Lexus CT200h, upper rear; and Fits 2006-2011 Chevrolet HHR, upper rear. Verify the 1.25 in. inside diameter and the straight routing before installation.

For best results, cut cleanly and squarely, then inspect the connection points for wear, corrosion, or residue before installing the new hose. Confirm that the hose length matches the application notes, especially where the listing specifies a minimum cut length or a particular trim dimension.
