Mammoth Performance HD Radiator Coolant Hose Kit 01-04 GM 6.6L Duramax

Description

Keep your Duramax cooling system ready for the demands of daily driving, towing, and heavy-duty use with this direct-fit silicone upper and lower radiator hose kit. Designed to replace aging OEM rubber hoses, this kit helps prevent coolant leaks and overheating caused by cracked, damaged, or collapsed factory hoses while providing improved resistance to heat and pressure. The factory plastic T-fittings on these trucks are also prone to cracking over time, making a reliable replacement for the cooling-system hoses an important upgrade. With the correct factory-style bends and connections, these hoses install without any cutting or modifications, making for a straightforward bolt-on upgrade. Constructed from high-strength silicone reinforced with multiple layers of heat-resistant fibers, these radiator hoses are designed to withstand the demanding temperatures and pressures of the 6.6L Duramax cooling system. The hoses maintain OEM fitment, meet or exceed OE specifications, and carry a maximum temperature rating of 350°F, while providing improved durability compared to aging factory rubber. T-bolt clamps are included for installation. Designed specifically for 2001–2004 Chevrolet Silverado and GMC Sierra 2500HD/3500HD trucks equipped with the 6.6L Duramax, this kit provides a durable, long-term replacement for the factory upper and lower radiator hoses.
