UD TRUCKS NISSAN DIESEL CONDOR CM87 CM88 CL87 CP87 NE6 NE6T 7.4L TURBO DIESEL ENGINE COOLING WATER PUMP ASSY (OE: 21010-95013 / 2101095013 / 21010-95014 / 21010-95015 / 21010-95016 / 21010-95017 / A-2017 / A2017 / GWN-43A)

Overview

The UD Trucks / Nissan Diesel Condor NE6 / NE6T Engine Water Pump Assembly (Water Pump Assy 21010-95013 / 2101095013 / A-2017 / GWN-43A) is a commercial-grade engine cooling system component engineered specifically for UD Trucks and Nissan Diesel Condor medium-to-heavy commercial transport trucks and buses powered by Nissan Diesel NE6 (7.4L naturally aspirated) and NE6T / NE6-TA (7.4L turbocharged) 6-cylinder direct-injection diesel engines (Condor CM87, CM88, CL87, CL88, CP87, and CMF87 commercial cargo lorries, wooden body trucks, tippers, dump trucks, and box vans). Built with a precision-machined pulley mounting flange hub, heavy-duty cast iron volute housing, precision multi-bolt mounting base, and high-efficiency cast internal impeller, this water pump delivers continuous, pressurized coolant circulation through the engine block, cylinder head, and oil cooler. Replacing a worn, noisy, bearing-seized, or leaking water pump restores optimal operating temperatures, preventing engine overheating, cylinder head warping, and blown head gaskets under sustained commercial transport workloads.

Key Dimensions & Specifications

• Top Pulley / Fan Mounting Hub: Pre-installed CNC-machined steel mounting flange featuring a multi-hole pattern and precision center pilot register collar for concentric pulley and fan clutch alignment.

• Heavy-Duty Cast Iron Housing: Thick-walled volute casing engineered with internal flow runners and external structural ribs to withstand high belt tension, vibration, and thermal stress.

• Precision-Machined Mounting Base: Multi-bolt perimeter mounting flange base with a flat CNC-machined sealing surface for direct installation onto the engine block / timing case water passage cavity.

• High-Capacity Bearing & Mechanical Shaft Seal: Industrial-grade sealed bearing assembly paired with a wear-resistant silicon-carbide/carbon mechanical seal to prevent bearing play and coolant weepage under heavy load.

• High-Flow Internal Impeller: Dynamically balanced cast impeller designed for continuous, high-volume coolant displacement across the 7.4L inline-6 cylinder block and oil cooler.

• Please verify your existing water pump top flange diameter, pilot collar step, and mounting bolt pattern against your old sample pump before ordering.

This 21010-95013 / A-2017 unit is engineered specifically for NE6 / NE6T 7.4L 6-cylinder diesel engines. Always verify your engine model code [NE6 / NE6T] and compare against your old sample pump prior to ordering.)

Why Choose Our Commercial Truck Parts?

• High-Volume 7.4L Turbo Coolant Circulation: Dynamically balanced internal impeller delivers steady, pressurized coolant circulation through the engine block, cylinder head, and oil cooler, eliminating hot spots under sustained hauling and turbo boost.

• Precision-Machined Pulley Flange Hub: CNC-machined steel hub ensures concentric fan and pulley alignment, preventing belt runout, vibration, and premature belt wear.

• Heavy-Duty Sealed Bearing & Mechanical Seal: High-capacity bearing cartridge paired with a wear-resistant silicon-carbide/carbon shaft seal withstands continuous radial belt loads and high cooling system pressures without developing shaft play or weeping.

• Rigid Cast Iron Volute Housing: Thick-walled cast iron body resists thermal fatigue, engine vibration, and cracking during heavy commercial operation.

• Ready Stock & Fast Shipping: Readily stocked for quick dispatch.
