What is the main purpose of the lower radiator hose?

The lower radiator hose is a crucial part of your vehicle's cooling system. It carries coolant from the engine's water pump to the bottom of the radiator, where it can be cooled before circulating back to the engine.

What material is this hose made from?

This Gates coolant hose is constructed from molded rubber, which is a standard material for radiator hoses designed to withstand the high temperatures and pressures within a vehicle's cooling system.

Does this hose come with clamps?

This product listing is for the molded coolant hose only. Clamps are typically sold separately, so you may need to purchase new hose clamps to ensure a secure fit.
