Its factory-molded shape helps maintain the correct path in applications where a straight hose will not match the original layout.\u003c\/p\u003e\u003cp\u003eCompatible with a wide range of Chevrolet Silverado, GMC Sierra, Tahoe, Yukon, and Cadillac Escalade applications, this hose is made for coolant, water, and air service and is also approved for marine use.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eEPDM construction for coolant-system service\u003c\/li\u003e\n\u003cli\u003eFactory-molded profile for a direct OE-style fit\u003c\/li\u003e\n\u003cli\u003eSmall inside diameter of 12 mm at both ends\u003c\/li\u003e\n\u003cli\u003e23 in. centerline length for radiator-to-reservoir routing\u003c\/li\u003e\n\u003cli\u003eApproved for coolant, water, air, and marine applications\u003c\/li\u003e\n\u003cli\u003eFits compact engine compartments where formed routing is required\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eProduct Details\u003c\/h2\u003e\u003cp\u003eGates Molded Heater Hose 18622 is built around the original hose shape used in many GM truck and SUV cooling systems. The molded design helps preserve the intended routing between the radiator and reservoir, which is important in crowded engine compartments on Silverado, Sierra, Avalanche, Tahoe, Yukon, and Escalade models. This part cross-references Continental 62938 for the same application.\u003c\/p\u003e\u003cp\u003eWith EPDM material and matched 12 mm end diameters, the hose is suited for consistent coolant transfer in vehicles that require a formed replacement rather than a universal cut-to-fit hose. The Gates 18622 part number is commonly searched for radiator to reservoir heater hose replacement on GM platforms.\u003c\/p\u003e\u003ch2\u003eCommon Uses\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacing a cracked or softened radiator-to-reservoir hose\u003c\/li\u003e\n\u003cli\u003eRestoring proper coolant routing on GM trucks and SUVs\u003c\/li\u003e\n\u003cli\u003eAddressing coolant seepage at a molded hose section\u003c\/li\u003e\n\u003cli\u003eCorrecting fitment issues caused by a straight universal hose\u003c\/li\u003e\n\u003cli\u003eServicing a hose that no longer holds its original formed shape\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes\u003c\/h2\u003e\u003cp\u003eVerify the hose route, centerline length, and 12 mm end diameters before installation. Compare the existing hose shape to the molded profile to confirm radiator-to-reservoir routing on your vehicle. Inspect adjoining fittings and clamps for wear, and replace any damaged sealing surfaces before installing the new hose.\u003c\/p\u003e\u003cp\u003eCompatible With 1999-2012 Chevrolet Silverado 1500, Radiator To Reservoir; 2006-2012 Chevrolet Silverado 2500, Radiator To Reservoir; 2007-2012 Chevrolet Avalanche, Radiator To Reservoir; 2000-2012 GMC Sierra 1500, Radiator To Reservoir; and additional Silverado, Sierra, Tahoe, Yukon, and Escalade applications listed in fitment.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eGates is known for producing OE-style fluid transfer components, and this molded heater hose follows that approach with a factory-shaped design and EPDM construction for cooling-system service.
