1994-1999 Cadillac DeVille Expansion Tank - Genuine W0133-1820133
For 1994-1999 Cadillac DeVilles this is the type of expansion tank needed. This OES genuine part fits next to the radiator in the car. As the engine runs, it creates heat, which causes the coolant in the system to expand. The expansion tank acts as the overflow for coolant that has expanded out of the engine. A leak in the expansion tank causes a coolant leak, which can lead to the engine overheating if a significant amount of coolant is lost. Check the vehicle make, model, and year because OES genuine parts are custom-built to a specific vehicle. Only use this expansion tank with Cadillac DeVilles made between 1994 and 1999.
