UD TRUCKS NISSAN DIESEL QUON GK GW CD CW CX CG GE13 GE13-T GE13-TD 13.0L TURBO ENGINE COOLING WATER PUMP ASSY (OE: 21010-00Z16 / 2101000Z16 / 21010-00Z17 / 21010-00Z18 / 21010-00Z2A / 21010-00Z2B / 21010-00Z2C / 21010-00Z2D)

Overview

The UD Trucks / Nissan Diesel Quon GE13 Engine Water Pump Assembly (Water Pump Assy 21010-00Z16 / 2101000Z16 / 21010-00Z17 / 21010-00Z2B) is a commercial-grade engine cooling system component engineered specifically for UD Trucks and Nissan Diesel Quon heavy commercial transport trucks, multi-axle tippers, and prime movers powered by Nissan Diesel GE13, GE13-T, GE13-TD, and GE13-TC (13.0L / 13,074cc) 24-valve inline-6 turbocharged intercooled diesel engines (UD Quon GK, GW, CD, CV, CW, CX, and CG series heavy prime movers, logging trucks, cargo lorries, dump trucks, and concrete mixers). Built with a precision-machined drive mechanism, high-strength cast volute housing, precision mounting base, and high-flow internal impeller configuration, this water pump delivers continuous, pressurized coolant circulation through the massive 13.0L 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 liner cavitation, and blown head gaskets under sustained heavy commercial payloads.

Key Dimensions & Specifications

• Drive Configuration: Precision-machined drive assembly engineered for exact engagement and continuous rotational balance under high engine RPM and torque.

• Housing & Port Design: Heavy-duty cast iron / alloy volute casing featuring CNC-machined coolant inlet/outlet flange ports and hose connections engineered for the UD GE13 engine cooling circuit.

• Mounting Base: Precision-machined perimeter mounting flange base with flat sealing surfaces for direct installation onto the engine timing case / block cavity.

• Bearing & Mechanical Seal: High-capacity sealed roller/ball bearing cartridge paired with an industrial-grade silicon-carbide/carbon mechanical shaft seal to withstand high cooling system pressures and resist shaft play.

• Coolant Flow Impeller: Dynamically balanced high-efficiency cast impeller engineered for maximum coolant flow and cavitation resistance.

• Please verify your existing water pump drive profile, mounting bolt layout, and coolant port orientation against your old sample pump before ordering.
