These high quality silicone hoses feature stock-type quick-disconnect fittings - no need to cut up your old hoses to get the connectors off! Unlike factory rubber hoses, silicone can withstand higher temperatures and pressures with minmal wear. Rubber will wear out and weaken so don't let it bite you when it counts! Silicone has been proven during extreme racing conditions and won't be the weak link that ruins your day.

The pre-attached stock-style plastic quick-disconnect fittings include new O-rings, providing a reliable leak-free seal during installation. We do not recommend re-using the temp sensor located in the lower radiator hose. You can add a new one to your order from the options below.

Over the years and with exposure to extremely hot coolant, the coolant hoses in your vehicle can take a beating. Being made of reinforced rubber, these hoses can fail in a number of ways. Splitting at a hose clamp, swelling, cracking, and breaking are just a few of the ways this hose can leave you stranded. Replace it at the first sign of wear to keep your coolant in your engine.
