What is a bypass coolant hose?

A bypass coolant hose is part of your vehicle's cooling system that allows coolant to flow through a specific circuit, often used to help the engine warm up faster or to regulate temperature in certain conditions. This hose is specifically shaped to fit that bypass path.

What material is this hose made from?

This Gates coolant hose is made from EPDM (ethylene propylene diene monomer) rubber. EPDM is a popular material for coolant hoses because it holds up well against high temperatures and the chemicals found in engine coolant.

Does this hose come with clamps?

This part number is for the molded coolant hose only. You will need to purchase hose clamps separately to secure it to the engine's coolant fittings.

Product Details

When you're replacing a coolant hose on your 1985-1992 Volkswagen Golf with a 1.8L engine, or similar Audi, Chevrolet, Geo, or Suzuki models, a molded bypass hose like this Gates 21517 is often the right choice. These hoses are shaped to fit specific routing paths in the engine bay, making installation much simpler than trying to bend and secure a straight hose. A leaky or collapsed coolant hose can quickly lead to overheating, so having a well-made replacement is key to keeping your engine running cool.

This hose is constructed from EPDM rubber, which is known for its resistance to heat and coolant chemicals. Gates designs these hoses to match the original equipment specifications, meaning it should fit right where the old one came out. The molded shape helps prevent kinks and ensures proper flow of coolant through the bypass circuit. It's a solid option for getting your cooling system back in reliable working order.
