Product Details

The Gates 52126 radiator coolant hose is shaped to follow the original hose path more closely than straight universal hose, which helps simplify replacement on vehicles that require a molded fit. Its EPDM material is commonly used in cooling system service because it is suited to coolant exposure and underhood temperatures.

Common Problems This Hose Can Address

• Coolant leaks from a cracked or aged radiator hose
• Softening, swelling, or collapse of the original hose
• Improper routing after a previous hose replacement
• Loss of coolant from worn hose ends or split sections
• Cooling system service on a Honda Civic or similar application requiring a molded 2.5-inch hose

Installation Notes and Tips

Verify hose diameter, centerline length, and routing before installation. Compare the original hose shape to the Gates 52126 to confirm the molded bends match the vehicle’s cooling system path. Inspect clamps, necks, and adjoining pipes for corrosion or damage before installing the new hose, and refill the cooling system with the correct coolant after service.
