GMB 130-1590 water pump for the 1986-1995 Buick LeSabre 3.8L and other vehicles moves coolant through the engine and runs off the serpentine belt.
A coolant leak near the pump, a whine or grinding from the bearing, or an engine that runs hot can mean the water pump is wearing out. A leaking hose, a stuck thermostat or a weak radiator cap can cause overheating and coolant loss too, so find the cause before you buy. The engine takes one pump.
This GMB water pump also fits the 1986-1993 Buick Riviera 3.8L and the 1992-1995 Chevrolet Lumina APV 3.8L. Open the "Vehicles it fits" section and check your exact model and engine; the fitment spans V6-3.0L, V6-3.3L and V6-3.8L engines.
