Gates 21959 upper cooling system components for the 1996 Buick LeSabre 3.8L and other vehicles is a single molded coolant hose that carries coolant through the cooling system.
Coolant seepage at the hose ends, cracks, or a hose that feels soft or swollen when the engine is cool can mean this part is worn, though a leaking water pump or a faulty radiator cap can be behind a coolant loss as well, so find the cause first. Only one goes in the upper hose position on the engine, and this listing is one hose.
It is a direct-fit replacement for the 1995-1996 Buick Park Avenue 3.8L and the 1995-1996 Oldsmobile 88 3.8L. If your car is not named here, open the "Vehicles it fits" section and check your exact model and engine.
