Installation Guide
- Ensure the excavator engine is completely cool and the battery is disconnected before beginning work.
- Drain the existing engine coolant into a suitable, environmentally compliant container.
- Remove the drive belt, cooling fan, and any obstructing hoses to access the old water pump.
- Unbolt and remove the faulty pump. Thoroughly clean the engine block mating surface to remove any old gasket material or debris.
- Fit the supplied housing gasket and smaller seal, then bolt the new pump on. Tighten the pump-to-block bolts to 1.9–2.9 kg·m (14–21 lbf·ft).
- Reattach the hoses, cooling fan, and drive belt. Refill the system with the correct specification of engine coolant and bleed any air from the system before starting the engine to check for leaks.

Spot on replacement. The 8972541481 pump matched the stamp on our ZX55. Aluminium housing, and the housing gasket and round seal in the box seated cleanly. Saved us a fortune compared to main dealer prices.
Fast UK dispatch saved the day. We had a 4LE1 down on site with a failed coolant pump. Ordered this 8972541481 unit, it arrived quickly, and the excavator was back digging within 48 hours.
Good solid aluminium pump. The pulley hub lined up on our EX55 4LE1 with no drama. Dropped a star only because the outer carton was a bit battered in transit, but the pump and gaskets were well protected inside.
I've bought aftermarket excavator engine water pumps before that didn't line up properly, but this one was an exact match for the 8-94140341-0 part. Highly recommend WaterInpos for plant parts.
Perfect fitment for our E55 4LE1. Engine is holding temperature again with no leaks from the weep hole. Great value for this aluminium coolant pump.
Very happy with the 4LE1 coolant pump. Housing gasket and smaller round seal in the box; we reused the original mounting bolts as usual. Build quality is on par with the unit we took off.
