Best Practices

If the vehicle has a heater control valve attached to the heater hoses, they should all be replaced at the same time.

We recommend using molded coolant hoses rather than "universal" hoses. Universal hoses can be deformed by pressure and heat and are prone to failure earlier than hoses designed to fit your vehicle.

We recommend replacing the hose clamps, as the clamps will weaken over time and new clamps will help prevent coolant leaks.

Common Symptoms

Coolant hoses can be damaged by oil leaks. The issue should be addressed in order to avoid damaging the new hoses.
