Detailed Description

Gates 21482 is a molded coolant hose engineered for lower radiator hose applications where the original hose follows a formed path between the engine and cooling system components. The EPDM material is commonly used in coolant service because it handles heat and coolant exposure well, while the molded shape helps maintain the intended routing and fit. This part number 21482 is listed for 1985-1986 Buick Century, 1985-1986 Chevrolet Celebrity, 1985-1986 Oldsmobile Cutlass Ciera, and 1985-1986 Pontiac 6000 in the lower position.

Common Repair Uses

• Replacing a cracked or softened lower radiator hose

• Correcting fitment issues caused by an incorrect straight hose
• Addressing coolant loss at the lower hose connection points
• Replacing a hose that no longer holds its molded shape

Installation Notes

Verify the hose routing, end diameters, and centerline length before installation. Drain coolant as needed, inspect the mating necks and clamps, and confirm the hose seats fully without twist or kinking. For best results, replace any worn clamps and check the cooling system for leaks after refill and warm-up.
