What material is this coolant hose made from?

This coolant hose is constructed from heat-resistant EPDM rubber. This material is chosen for its ability to withstand high engine temperatures and resist degradation from coolant and engine heat.

Does this hose come with clamps?

This part is for the molded coolant hose only and does not include hose clamps. You will need to use your existing clamps or purchase new ones separately.

Why is it important to replace a coolant hose?

Coolant hoses can become brittle and crack over time due to heat and age, leading to leaks. A leaking hose can cause your engine to overheat, potentially leading to serious damage.

Product Details

If your 1986-1989 Nissan D21 with the 3.0L V-6 is showing signs of a coolant leak from the upper hose, or if the hose itself is cracked and brittle, it's time for a replacement. This molded coolant hose from Gates is designed to connect your engine's water outlet to the coolant pipe, ensuring proper coolant flow to keep your engine from overheating.

Gates uses a heat-resistant EPDM rubber compound for this hose, similar to what the original equipment uses. This material is built to withstand the high temperatures and pressure found in your cooling system, resisting degradation from coolant chemicals and engine heat. The molded shape means it follows the factory routing precisely, making installation straightforward without needing to fight a stiff, generic hose into place. It's a well-built part that gets the job done right.

When replacing your upper coolant hose, it's a good idea to inspect your lower hose and thermostat as well. If they're showing wear, consider replacing them at the same time to prevent future issues and ensure your cooling system is in top shape.
