Gates 24836 Silicone Coolant Hose

This straight silicone coolant hose has a 2-1/4 inch inside diameter and a 36 inch length. It is built for automotive cooling systems that require high-temperature resistance and flexibility. The blue cover identifies the hose in complex routing.

Installation notes for straight bulk hose

The hose is supplied as a 36 inch straight length without pre-formed bends or end fittings. Installers must cut it to the exact routing length and secure each end with suitable clamps. A common issue is using clamps that are too narrow for the thick silicone wall, which can lead to leaks under pressure.

Compatibility checks before ordering

Verify that the 2-1/4 inch inside diameter matches the outer diameter of your existing pipes or fittings. Confirm the system operating pressure does not exceed 75 psi at 70 degrees Fahrenheit. Ensure the temperature range of -70 to 350 degrees Fahrenheit covers your application, and that SAE 20R1 meets any required standards. This hose is not for fuel, oil or hydraulic lines.

Questions about this item

How can I confirm the hose is sealing correctly once installed?

Pressurise the system to the rated 75 psi at 70 °F and check for leaks; the hose meets SAE 20R1 so it should hold without weeping.

What comes with the hose and do I need separate clamps?

The box contains the 36 in straight blue silicone hose only; clamps or fittings are not included and must be sourced separately.

Should I choose a different length or diameter for my application?

This part number 24836 is a single 2-1/4 in inside diameter by 36 in length; select another Gates part number if a different size is required.
