Gates 99-05 Buick LeSabre V6 3.8L Lower Coolant Elbow

This is the Gates 91051-20 lower coolant elbow, a direct replacement part for many GM vehicles from the late 90s and early 2000s. It's specifically designed to connect coolant hoses to the engine block or water pump, ensuring proper coolant flow to keep your engine from overheating. If you're working on a 1999-2005 Buick LeSabre, 2000-2005 Chevrolet Impala, or a 1999-2008 Pontiac Grand Prix, this elbow is likely the part you need to replace a cracked or leaking original.

Made from durable materials, this elbow is built to withstand the heat and pressure of the cooling system. It's a straightforward replacement part that fits right into the existing hose and mounting points. Replacing a faulty coolant elbow is important because leaks can lead to significant engine damage if the coolant level drops too low. This part helps ensure your cooling system stays sealed and functions as intended.
