It’s a big responsibility to prevent your vehicle from overheating, and Gates Radiator Hoses are more than up to the task. Designed to resist the leading cause of untimely hose failure – electromechanical degradation – this top-of-the-line replacement hose is flexible without giving, and installs directly in place of your ousted OE hose.
The magic is truly in the making when it comes to the Gates Replacement Radiator Hose. It combines advanced fiber construction with a premium EPDM rubber compound for exceptional durability and resistance to high-pressure extremes that go hand-in-hand with full-throttle driving. The EPDM also prolongs the effectiveness of coolant because it’s up to 15 times better against water permeation than the silicone in most hoses.
Gates Radiator Hoses perform according to SAE 20R5 type EC class D-2 specs and are permissible with marine applications – but not with fuel or oil transfer applications. Your Gates Radiator Hose is supported by a Limited Lifetime Warranty.
