Volkswagen Golf III / Vento / Passat 1.9 TD & TDI Water Pump with Housing 037121010A

Product overview

This engine water pump comes complete with its housing and is referenced to OE number 037121010A. It is listed primarily for older Volkswagen models with 1.9 litre turbo-diesel engines. The water pump keeps coolant moving between the engine block, radiator and heater, and a worn bearing or leaking seal can quickly lead to overheating. Supplying the pump already mounted in its housing can make replacement quicker and reduces the risk of reusing a corroded casting.

Vehicle compatibility

Listed fitment data includes the Volkswagen Golf III (1H1, 1991–1998), Vento (1H2, 1991–1998) and Passat sedan and Variant (3A2, 3A5, 35I, 1988–1997) with 1.9 TD, 1.9 TDI and GTD engines. The listing also mentions Skoda Favorit and Forman and Audi 80 and 90. In addition, a second reference number, 5184498AJ, brings in a list of Chrysler, Jeep, Dodge, Ram and Alfa Romeo vehicles. Those applications use a completely different engine design, so we do not consider them confirmed for this pump. The full list contains 49 rows.

Technical specifications

Installation requirements

On many of these engines the pump is driven by the timing belt, so fitting is best left to an experienced technician, and renewing the timing belt and tensioner at the same time is common practice. Drain the coolant with the engine cold, clean all mating faces and refill with the specified coolant. Bleed out any air and check for leaks once warm.

Fitment checks before ordering

Because the listing data mixes unrelated vehicles, please confirm the OE number on your existing pump or check your VIN with our team before ordering.
