OEM 800177040 The XCMG Coolant Fill Hose 800177040 is a genuine OEM hose engineered to carry coolant from the fill point to the cooling system on XCMG hydraulic excavators.
Identified by part number 800177040, this factory-made coolant fill hose provides a flexible, sealed path for adding coolant and for connecting the expansion tank to the engine circuit.
It is produced from heat-resistant EPDM rubber with synthetic reinforcement and a tough outer cover that resists coolant, heat, and abrasion.
Exact OEM inner diameter, length, and molded bend allow direct replacement without cutting, clamping adapters, or rerouting the line.
By keeping coolant flow sealed and unrestricted, this hose protects the water pump, radiator, and engine from air pockets and overheating.
The 800177040 Coolant Fill Hose uses heat-resistant EPDM rubber that stays flexible and sealed through hot coolant and cold-start cycles.
Synthetic fiber reinforcement keeps the hose from ballooning or collapsing when the cooling system pressure rises during operation.
The molded shape follows the OEM route exactly, so the hose clears brackets, fan blades, and nearby engine parts without contact.
A tough outer cover resists abrasion from vibration and rubbing, which is a common cause of coolant leaks on excavators.
Exact inner diameter and length let the original clamps seat properly, so the hose seals without extra sealant or adapters.
Flexible construction absorbs engine movement, which reduces stress on radiator necks, expansion tank fittings, and pipe joints.
Production starts with certified EPDM compound tested for hardness, tensile strength, heat aging, and coolant resistance before building.
The hose is built on a mandrel that matches the OEM bend path, so the finished part keeps its shape and full inner diameter.
Vulcanization bonds tube, reinforcement, and cover into one strong wall, and trimming removes flash from both ends.
Inspectors check inner diameter, length, wall thickness, bend angle, and surface quality on samples from every batch.
Batch records let XCMG trace each 800177040 hose back to its compound lot and curing press, so quality questions are resolved quickly.
The coolant fill hose provides a sealed path for adding coolant and for connecting the expansion tank to the engine cooling circuit.
A cracked or loose fill hose admits air, which causes coolant loss, air locks, and unstable engine temperature during operation.
The genuine 800177040 keeps the fill path sealed, so the water pump circulates coolant without drawing air into the system.
Correct routing away from heat sources prevents the hose from hardening and cracking, which extends service life and avoids leaks.
Stable coolant level and flow keep engine temperature in range, protecting head gaskets, pistons, and hydraulic oil performance.
The 800177040 Coolant Fill Hose installs with hose clamp pliers and standard hand tools during scheduled cooling system service.
Let the engine cool completely, release cooling system pressure, and drain coolant to the level recommended in the workshop manual.
Loosen the clamps, twist and pull the old hose free, then clean both fittings and check for corrosion or cracked necks.
Slide the new hose onto both fittings without twisting it, and position the clamps behind the bead at each end.
Refill with the specified coolant mixture, run the engine to operating temperature, and check for leaks at both connections.
During routine maintenance, squeeze the hose to check for softness or cracking, and replace it before it bursts on site.
Every 800177040 hose is produced in an ISO 9001 and ISO 14001 certified plant with traceability from compound to packed carton.
Incoming rubber is tested for hardness and heat resistance, and finished hoses are measured for bore, length, and bend angle.
During production, curing time, temperature, and mandrel condition are monitored so every hose keeps its molded shape.
Post-production checks include visual inspection, dimensional verification, and a trial fit on the XCMG cooling circuit fixture.
Sample hoses from each batch undergo pressure, heat aging, and coolant soak tests to confirm long-term performance.
Low-cost aftermarket coolant fill hoses often use low-grade rubber that hardens, swells, or cracks from heat and coolant additives.
A hose with the wrong bend or diameter can kink after installation, which blocks coolant flow and causes overheating.
The genuine 800177040 is molded to the XCMG drawing, so bore, length, bend path, and material match the original part.
Using genuine XCMG parts also preserves warranty coverage, protects resale value, and maintains compatibility with other OEM components.
Backed by XCMG global quality standards and technical support, this coolant fill hose delivers dependable flow in harsh conditions.
Choosing the genuine 800177040 hose prevents a small coolant weep from turning into an expensive engine overheating repair.
A burst fill hose can drain the cooling system quickly, which warps heads and damages gaskets within minutes.
Durable EPDM and proper reinforcement keep the hose functional across a long service life, reducing replacement frequency.
Reliable cooling also extends hose, seal, and oil life, lowering the total cost of ownership for fleet operators.
Fleet records from construction and mining operations show genuine XCMG cooling parts cut engine-related downtime.
XCMG applies sustainable manufacturing to the 800177040 hose through efficient mandrel building and reduced material waste.
The long service life of the hose reduces material consumption and lowers the environmental footprint of replacement parts.
Preventing coolant leaks protects soil and groundwater and supports compliance on environmentally sensitive sites.
Rubber materials in this component comply with RoHS and REACH rules for safe handling and responsible disposal.
The 800177040 Coolant Fill Hose is held in XCMG regional distribution centres across North America, Europe, Asia, and Australia.
Each hose is sleeved and packed in a sturdy carton that protects it from kinking, dust, and ultraviolet exposure in transit.
For fleet-wide orders, XCMG provides volume pricing and consolidated freight options that simplify planning and reduce cost.
Real-time stock visibility and dedicated supply chain support help fill urgent requests quickly, shortening downtime on active projects.
Robust packaging preserves factory condition until installation, preventing the deformation and cracking common in stored hoses.
The XCMG Coolant Fill Hose 800177040 is a vital connection component for XCMG excavators, linking coolant fill points and expansion tanks.
Its heat-resistant EPDM tube, reinforcement, and molded shape deliver dependable flow in hot, wet, and dusty environments.
By preventing kinks and leaks, this coolant fill hose reduces downtime, lowers maintenance costs, and extends engine service life.
