Me995358 Me075156 Me075293 Truck Water Pump for Mitsubishi Fuso 6D16t

1. Quick Notice

Confirm your engine code (6D16T) and the original water pump part number before ordering. This listing covers three cross-reference numbers: ME995358, ME075156, and ME075293. Verify pulley bolt pattern, housing shape, and impeller type against your current pump. Professional installation required. Replace the thermostat and gasket simultaneously.

2. Description

Description: This water pump is a direct-fit cooling system component for Mitsubishi Fuso 6D16T diesel engines. The pump circulates coolant through the engine block, cylinder head, and radiator. Constructed with a cast iron housing, sealed ball bearings, and a pressed steel or cast impeller. The shaft seal uses carbon ceramic technology to prevent coolant leakage past the bearing. Fits Fuso Fighter, Super Great, and heavy Canter models equipped with the turbocharged 6D16T engine. Cross-reference numbers ME995358, ME075156, and ME075293 all refer to the same pump specification. A failed pump produces coolant leaks from the weep hole, bearing noise, or insufficient coolant flow leading to engine overheating. Replacement includes the pump housing only. The gasket, pulley, and bolts are reused or ordered separately.

4. Custom Content

Gasket and Sealant: A new gasket is required for installation. Clean both mating surfaces on the pump housing and engine block. Remove all old gasket material using a plastic scraper. Do not use a metal blade on aluminum timing housings. Apply a thin bead of high-temperature RTV silicone at the joint corners where the gasket meets the timing cover. No additional sealant is needed on the main gasket surface if using a quality paper or composite gasket.

Coolant Type: Use ethylene glycol antifreeze mixed with distilled water at a 50/50 ratio. Heavy-duty diesel coolant with supplemental coolant additives is preferred. Do not use tap water. Minerals in tap water accelerate seal wear and clog radiator passages. Flush the cooling system completely before installing the new pump.

Torque Specifications: Tighten mounting bolts in a cross pattern to 25 to 30 Nm. Exceeding 35 Nm cracks the cast iron housing. Tighten the pulley bolts to 20 to 25 Nm. Re-torque all bolts after the first heat cycle.

5. FAQ 

Q1: Which part number is correct for my truck?
A1: ME995358, ME075156, and ME075293 all refer to the same water pump specification. Any of these numbers cross-reference to the same component. Order by any of the three numbers.

Q2: Does this pump fit a naturally aspirated 6D16 engine?
A2: Check your original pump. Turbocharged 6D16T engines use a pump with higher flow rate. Naturally aspirated 6D16 engines may use a different pump with smaller impeller. Compare housing shapes before ordering.

Q3: How do I know if my water pump is failing?
A3: Coolant dripping from the weep hole under the pump, growling or rumbling noise from the front of the engine, coolant loss with no external leaks, or engine overheating at low speed. A wobbly pulley indicates bearing failure.

Q4: What is the weep hole on the water pump?
A4: The weep hole is a small port between the bearing and the seal. When the internal seal fails, coolant escapes through this hole instead of entering the bearing. Coolant at the weep hole means immediate pump replacement is required.

Q5: Can I replace only the pump without draining all coolant?
A5: No. The water pump is mounted low on the engine front cover. Draining the cooling system below pump level is necessary. Replace the coolant completely if it appears rusty or contaminated.

Q6: What is the difference between ME075156 and ME075293?
A6: The pump body and impeller are identical. The difference is typically the included pulley flange or bolt pattern. ME075293 may have a different pulley mounting surface. Compare your original pump physically before ordering.

Q7: Does this pump come with a new pulley?
A7: No. The pulley from your old pump must be reused. Inspect the pulley for grooves or distortion before transferring to the new pump.

Q8: What happens if I install the pump without a gasket?
A8: Immediate coolant leakage occurs. The gasket seals the interface between the pump housing and engine block. Never use liquid sealant alone. A physical gasket is required.

Q9: How long does a typical water pump last on a 6D16T engine?
A9: Original equipment pumps typically last 100,000 to 150,000 kilometers in normal service. Heavy towing or frequent idling reduces lifespan. Aftermarket pump life varies by manufacturer.

Q10: Why does my new pump make noise immediately after installation?
A10: Air trapped in the cooling system causes cavitation noise. Bleed the system by running the engine with the radiator cap open until the thermostat opens. Refill as needed. If noise continues, verify belt tension and pulley alignment.
