The genuine XCMG Engine Oil Cooler with OEM number 800172801 is a heavy-duty plate-and-fin heat exchanger designed for XCMG articulated dump trucks, wheel loaders, and off-highway vehicles equipped with Cummins, Deutz, or XCMG engines. This oil cooler efficiently removes excess heat from engine lubricating oil, maintaining optimal viscosity and preventing thermal degradation. The 800172801 cooler ensures reliable operation in extreme ambient temperatures from -40°C to +55°C, extending engine life and reducing unplanned downtime.
The XCMG Engine Oil Cooler 800172801 is a critical component for maintaining engine oil within the ideal 95°C–115°C operating range. Excessive oil temperature (above 125°C) accelerates oxidation, increases sludge formation, and reduces bearing life. This cooler uses a high-efficiency plate-and-fin core with turbulent oil flow to maximize heat transfer while minimizing pressure drop.
On AD60 and AD80 articulated dump trucks, the 800172801 cooler is mounted directly on the engine block or remote-mounted near the radiator. Field data shows that using the genuine XCMG oil cooler reduces peak oil temperature by 18°C under full load at 40°C ambient, compared to no cooler. This reduction extends oil change intervals by 30% and reduces top-end wear by 50%.
The 800172801 oil cooler features a vacuum-brazed aluminum core consisting of 26 oil plates and 27 coolant plates. The offset-fin design creates high turbulence, achieving a heat transfer coefficient of >2500 W/m²·K. Unlike gasketed coolers, the brazed construction eliminates internal leak paths between oil and coolant circuits, preventing catastrophic contamination.
Each core is pressure-tested at 2.5 MPa (oil side) and 1.5 MPa (coolant side) during production. The aluminum alloy (3003) provides excellent corrosion resistance even with extended-life coolants. The core is also resistant to thermal fatigue, tested for 10,000 cycles from -40°C to +120°C without leakage or deformation.
The die-cast aluminum housing of the 800172801 is coated with a cathodic E-coat (electrophoretic) that provides superior corrosion resistance in salty, humid, or chemically aggressive environments. The housing also incorporates integral mounting bosses that align precisely with XCMG engine castings, eliminating the need for adapters or brackets.
All sealing surfaces use precision-machined O-ring grooves. The kit includes a new NBR gasket and stainless steel bolts. For high-temperature synthetic oils (e.g., 5W-40), an FKM gasket is available. The cooler’s ports are oriented for direct hose connection without sharp bends, reducing flow restriction and hose chafing.
To replace the engine oil cooler, drain the engine oil and coolant. Remove the old cooler by unbolting four M10 bolts (torque 45 Nm). Clean the mounting surface on the engine block and inspect for flatness. Install the new gasket (provided) and place the cooler, ensuring alignment dowels engage. Torque bolts to 50 Nm in a cross pattern.
Reconnect oil and coolant hoses using new clamps. Refill with the correct engine oil (15W-40) and coolant (50/50 ethylene-glycol). Start the engine and check for leaks. Run until thermostat opens, then re-torque the bolts after the first heat cycle. Oil cooler replacement is recommended every 8,000 hours or whenever the engine is overhauled.
Inspect the cooler annually for external corrosion, bent fins, or hose barb damage. If oil and coolant mix (emulsion on dipstick or oil in coolant), the core may be cracked. Replace immediately to avoid engine bearing failure. XCMG recommends always replacing the oil filter when changing the cooler to prevent debris from entering the new unit.
Counterfeit oil coolers sold as OEM 800172801 often use low-quality aluminum and inadequate brazing, leading to core leaks or burst seams under pressure. Symptoms include milky oil (coolant ingress) or oil spots in the coolant expansion tank. Genuine XCMG coolers feature a laser-etched part number on the housing and a vacuum test certificate in the box.
Another common counterfeit issue is undersized core (fewer plates) resulting in 30% less cooling capacity. This causes high oil temperatures (above 125°C) under load, leading to accelerated engine wear. Always verify the number of cooling plates (visible through the inlet/outlet) – genuine has 26 plates; copies often have 18–20.
Corrosion: Non-genuine housings lack E-coat and may corrode through within 18 months in coastal operations. Genuine XCMG 800172801 coolers pass 500 hours of salt spray testing. Look for the yellow E-coat color inside the mounting flanges.
Maintaining proper oil temperature with the 800172801 cooler reduces internal friction, improving fuel economy by 1.5–2.5%. A cooler that has lost efficiency (e.g., clogged fins) forces the engine to work harder, consuming more fuel. Fleet tests show that replacing a degraded oil cooler recovers fuel savings of $800 per year per truck.
Predictive maintenance: Monitor oil temperature via telematics. A gradual increase in oil temperature at constant load indicates cooler fouling or core degradation. Scheduled cleaning or replacement before failure avoids unscheduled downtime. Using the genuine XCMG cooler reduces oil oxidation, extending oil life from 500 hours to 650 hours in severe mining conditions.
Payback analysis: The XCMG 800172801 cooler costs approximately $320. Compared to aftermarket alternatives that require adapters and modifications ($250 + labor), the direct-fit OEM saves 2 hours of installation labor ($120). Combined with fuel savings and extended oil life, ROI is achieved within 3 months.
Every XCMG Engine Oil Cooler 800172801 is manufactured in an IATF 16949-certified facility. Each unit undergoes 100% leak testing (helium mass spectrometry), pressure cycling (0–1.8 MPa, 100,000 cycles), and thermal shock testing (10,000 cycles from -40°C to +120°C). XCMG provides a 24-month warranty against core leaks or housing defects.
Global stock is maintained in Xuzhou, Dubai, Rotterdam, Houston, and Singapore. Emergency orders are shipped within 24 hours. XCMG also offers a core exchange program – return your failed cooler for a discount on a new genuine unit. Each cooler is packaged in a foam-lined box with the gasket kit and installation instructions.
To verify authenticity, scan the QR code on the packaging – it links to the individual unit’s test report. Always insist on genuine XCMG 800172801; counterfeit coolers have been known to cause severe engine damage due to oil starvation from internal blockage.
XCMG validated the 800172801 oil cooler in extreme conditions: -45°C cold start (Heihe, China), +55°C desert operation (Dubai), and high-salt coastal mining (Indonesia). The cooler maintained leak-free operation after 5,000 hours of field service. The brazed aluminum core showed no sign of fatigue or corrosion.
For high-vibration applications (rock trucks with severe haul roads), the cooler passed 200 hours of random vibration at 15g RMS. Mounting bolts remained torqued, and no fin cracks developed. The E-coat housing resisted stone chipping and abrasion.
For extremely dusty environments (coal mines), XCMG offers a fine-mesh stone guard (part 800172801-ACC1) that protects the cooler core from debris impact without reducing airflow. This accessory is recommended for all underground applications.
