What does a bypass heater hose do?

A bypass heater hose connects your engine's cooling system to the heater core inside your vehicle's cabin. Hot coolant flows through this hose to the heater core, which then uses a fan to blow warm air into the passenger compartment.

Why is the hose molded?

The molded shape is designed to match the specific routing of the original factory hose. This ensures it fits correctly without kinking or needing to be forced, which makes installation easier and helps maintain proper coolant flow.

What material is this hose made from?

This heater hose is made from EPDM (ethylene propylene diene monomer) rubber. EPDM is a popular choice for coolant hoses because it offers good resistance to heat, ozone, and coolant chemicals, helping it last longer.

Product Details

When your heater isn't blowing warm air, a cracked or leaking heater hose is often the culprit. This molded bypass heater hose from Gates is designed to replace the original hose on a wide range of vehicles, including many Honda Civics, Accords, and Acura Integras from the late 80s through the early 2000s. It connects your engine's cooling system to the heater core, allowing hot coolant to circulate and warm your cabin.

Gates makes this hose from EPDM rubber, which is known for its resistance to heat and coolant chemicals. The molded shape means it follows the factory routing precisely, making installation straightforward without needing to bend or force a universal hose. This ensures a secure fit and helps prevent kinks that could restrict coolant flow. It's a well-built replacement part that gets your heating system back to normal operation.
