What is a bypass heater hose?

A bypass heater hose is part of your vehicle's cooling system. It circulates hot engine coolant to the heater core, which then warms the air blown into the cabin. This specific hose is designed to bypass certain components or follow a particular routing as specified by the manufacturer.

What material is this hose made from?

This Gates heater hose is constructed from EPDM (ethylene propylene diene monomer) rubber. This material is known for its good resistance to heat, ozone, and coolant chemicals, which helps it last longer in demanding engine bay conditions.

Does this hose come with clamps?

This product listing is for the molded heater hose only. Clamps are typically sold separately, and it's recommended to use new, corrosion-resistant clamps when installing any new heater hose.

Product Details

This is the Gates molded bypass heater hose, part number 18201. It's designed to fit a wide range of vehicles, including popular models like the 2000-2006 Toyota Tundra with the 4.7L V8 engine, the 1998-2007 Lexus LX470, and the 1990-1996 Nissan 300ZX. Heater hoses are crucial for your vehicle's climate control system, circulating hot coolant from the engine to the heater core to warm the cabin.

Gates makes these hoses from a EPDM rubber compound that resists heat and coolant degradation, helping to ensure a long service life. The molded shape means it follows the factory routing precisely, making installation straightforward without needing to bend or force a universal hose. This direct-fit design helps prevent kinks or stress points that could lead to premature failure.
