Parts for your 2002 Nissan Navara-Water pump

2002 Nissan Navara water pump — fitment, purpose and servicing

Based on technical sources, a water pump is absolutely relevant and fitted to the 2002 Nissan Navara (D22). The Nissan D22 Factory Service Manual (Cooling System section, 1997–2004 coverage) details inspection and replacement of the water pump for the KA24DE petrol and the YD25DDTi and ZD30DDT diesels. Nissan FAST parts catalogues and aftermarket application guides from Gates and Dayco also list specific water pump part numbers for these engines, confirming fitment.

On this ute, the water pump’s job is to keep coolant moving through the block, head, heater core and radiator so the engine stays in its happy temperature range. Good flow matters even more on turbo-diesel variants under load — towing, beach work or long hill climbs can push temps up fast. A healthy pump helps avoid hot spots, warped heads and the kind of overheating dramas that ruin weekends.

Most 2002 D22 engines drive the pump off the accessory belt, so access is straightforward compared with timing-belt-driven setups. During routine servicing, it’s smart to:

• Inspect for leaks at the weep hole, dried coolant crust, pulley wobble or bearing noise.
• Check belt condition and tension
