Use OE 10128334 to Identify the Water Pump Drive Shaft Coupler

This water pump drive shaft coupler is associated with OE number 10128334. Because this category contains one steel coupling, the OE reference and vehicle application are the strongest fitment guides. Do not choose it from the words “water pump” alone. The original coupler's size and connection ends should agree with the part identified by that number.

What the Water Pump Shaft Coupling Connects

The coupling transfers rotation through the water-pump drive arrangement. It is not the complete water pump, a pulley, an engine driveshaft, a coolant outlet, or a hose connector. The repair should specifically call for the small drive coupling. If the pump, pulley, or another cooling-system component is damaged, that item must be selected separately rather than being assumed to come with the coupler.

Check Coupler Length, Diameter, and End Shape

The specified steel coupler measures about 39.2 mm in length and 17.8 mm in diameter. Use those dimensions with the shape of both connection ends. A close overall size is not enough if the ends do not engage the same drive components. Measure or inspect the removed coupler and use OE 10128334 to keep the physical comparison tied to the correct application.

Models Listed for This Water Pump Coupler

The stated applications include 1994-1996 Buick Roadmaster, 1993-1997 Chevrolet Camaro and Pontiac Firebird, 1994-1996 Chevrolet Caprice and Impala, and 1992-1996 Chevrolet Corvette. Use the model and year together with OE 10128334. The presence of a water pump in another vehicle does not make this coupling universal or suitable for a different drive design.

Frequently Asked Questions (FAQ)

Is this coupler the complete water pump?

No. It is the small drive coupling that transfers rotation in the water-pump drive arrangement. The pump assembly, pulley, and other cooling-system parts are separate.

Which OE number is associated with this water pump coupler?

The specified OE reference is 10128334. Use that number with the vehicle year and model, then look at the original coupler’s two connection ends.

What dimensions should I use for the coupler?

This coupler is about 39.2 mm long and 17.8 mm in diameter. Use those measurements together with the end shape rather than relying on length alone.

Is this water pump drive shaft coupler universal?

No. It is identified for specific Buick, Chevrolet, and Pontiac applications. Use the named model, year range, OE number, and physical dimensions before ordering.
