OEM 800171770 The XCMG Radiator Auxiliary Tank 800171770 is a genuine OEM expansion tank that stores coolant and absorbs volume changes in the cooling system of XCMG excavators.
Marked with part number 800171770, this factory tank gives technicians a sealed reserve that keeps the radiator full as the engine heats and cools.
The body is molded from heat and coolant-resistant plastic, fitted with a pressure cap and hose nipples, then checked for leaks at every joint.
Exact mounting points, filler neck and outlet position let the tank drop into the original bracket without drilling, cutting or adapting hoses.
A proper reserve volume and clear level marks make daily coolant checks quick, so low-level overheating is caught before it damages the engine.
Every tank is pressure tested and dimensionally verified before packing, so the unit that arrives matches the XCMG drawing specification.
The 800171770 auxiliary tank uses coolant-resistant plastic that keeps its shape and color after years of hot and cold cycling.
Its pressure cap opens at the rated setting, so excess pressure vents safely instead of splitting hoses or radiator seams.
Sealed joints and molded nipples prevent weeping, which keeps the engine bay clean and preserves the coolant charge.
Clear minimum and maximum marks make daily checks fast, so a low level is spotted before the engine overheats.
Mounting points follow the OEM bracket, so the tank hangs correctly and does not vibrate against nearby components.
Correct capacity gives enough reserve for thermal expansion, so the radiator stays full through long shifts.
Because the tank fits straight from the carton, a technician completes the job in minutes instead of fabricating a substitute.
Production starts with certified coolant-resistant plastic checked for grade, wall thickness and freedom from contamination.
Blow molding forms the body to the drawing shape, and the filler neck and outlet are welded or molded in the same cycle.
Each tank is pressure tested under water, so any pinhole at a seam or nipple shows up before the unit leaves the line.
Inspectors verify capacity, mounting points, neck size and level marks against a checking fixture for this part number.
Batch records trace every 800171770 tank back to its plastic lot and molding machine, so quality questions close quickly.
The tank gives coolant somewhere to go when it expands with heat, and returns it to the radiator as the engine cools.
A cracked or leaking tank drops the coolant level, which lets air enter the system and causes hot spots and overheating.
The genuine 800171770 keeps the circuit sealed, so the radiator stays full and the water pump moves liquid, not air.
Correct mounting keeps the tank away from exhaust heat and moving parts, which prevents softening and abrasion damage.
Stable cooling protects the cylinder head, gaskets and liners, which keeps engine output and machine uptime predictable.
The 800171770 auxiliary tank installs with a socket set and hose clamp pliers during scheduled cooling system service.
Let the engine cool fully, then place a drain pan under the tank before loosening the cap or any hose.
Drain the coolant to a safe level, remove the old tank and inspect the bracket and hoses for cracks or hardening.
Set the new tank on the bracket, tighten the fasteners by hand first, then torque them to the specified value.
Fit the hoses and clamps, refill with the correct coolant mix, and run the engine to purge trapped air.
Check the level after the engine cools, and look for weeping at the neck, outlet and cap seal.
At service intervals, inspect the tank for cracks, discoloration or a loose cap, and replace it before a leak strands the machine.
Every 800171770 tank is made in a plant certified to ISO 9001 and ISO 14001, with records from plastic lot to sealed carton.
Incoming plastic is checked for grade and dryness, and finished tanks are gauged for capacity, neck size and mounting points.
Each unit is pressure tested and cap tested, so the relief valve opens at the right setting and the body holds without weeping.
Final checks cover appearance, dimensions and a trial fit on the XCMG cooling system fixture used for this machine series.
Samples from every batch undergo heat ageing, coolant soak and vibration tests to prove long-term performance.
Cheap copies often use brittle plastic that cracks at the neck or seam after a few heat cycles in service.
A tank with the wrong capacity or cap rating can over-pressurize the system, which pushes coolant out and damages hoses.
The genuine 800171770 is molded to the XCMG drawing, so capacity, neck, outlet and mounting points match the original part.
Staying with genuine XCMG parts keeps warranty cover intact, protects resale value and avoids clashes with other OEM items.
Every tank carries XCMG global quality standards and technical backing, so it works through long shifts in harsh ground.
Fitting the genuine 800171770 tank stops a small coolant weep from growing into an expensive engine repair.
A failed tank can drain the cooling system fast, which overheats the engine and can warp the cylinder head.
Correct plastic and sound seals keep the tank working over a long life, which cuts how often it must be replaced.
Reliable cooling also extends radiator, pump and gasket life, which trims the total cost of ownership for fleets.
Maintenance logs from quarry and construction fleets show genuine XCMG cooling parts reduce unplanned stoppages.
XCMG builds the 800171770 tank with efficient molding cycles and tight material control that keep production scrap low.
A long working life means fewer replacements, which lowers the raw material and energy tied to each tank.
Containing coolant leaks protects soil and groundwater, helping operators meet rules on sensitive job sites.
The plastic in this part complies with RoHS and REACH requirements for safe handling and responsible disposal.
The 800171770 radiator auxiliary tank is stocked in XCMG depots serving North America, Europe, Asia and Australia.
Each tank is capped, bagged and boxed in strong cartons that guard against impact, dust and damp during transport.
Fleet buyers can request volume pricing and combined freight, which simplifies planning and lowers landed cost.
Live stock data and responsive supply teams help cover urgent requests fast, so machines return to work sooner.
Careful packing keeps the tank in factory condition until fitting, avoiding the cracks seen in badly stored stock.
