Gates Radiator Coolant Hose P/N:20700
Keep coolant moving between the radiator and engine with the Gates Radiator Coolant Hose 23136, the upper radiator hose that drops in as a direct-fit replacement for the 2006-2008 Buick Lucerne. This hose carries engine coolant along the upper flow path of the cooling system, and replacing a hardened, cracked, or leaking original helps keep that path sealed. If a failing upper hose is the source of a coolant leak or loss, this is the part that replaces it.
Inspect the clamps and connections during installation and refill with the correct coolant per the vehicle service information.
