XCMG 800358577 Overflow Tank (Alt. Drawing XGSX01-157-05 / Old 6723533) | Pressure Cap Matched

This XCMG Coolant Overflow Tank 800358577​ (Drawing No. XGSX01-157-05, Cross-ref 6723533) adopts a tri-code design where the numeric P/N, structural drawing No. and legacy cross-ref cross-verify each other, minimizing mis-ship risk during procurement and simplifying after-sales traceability. As a replenish node in the engine cooling circuit, the tank body is rotomolded from PA66/PE (HDPE+UV masterbatch optional per OEM drawing) for uniform wall thickness and seamless construction, resistant to thermal cycling (-40℃~+120℃ rated) and UV aging—no cracking or deformation under long-term outdoor duty. Level marks are calibrated for clear readability; inlet, return, overflow and sensor port (if applicable per drawing) align exactly with the original. Each matching pressure cap is retested for opening pressure and seal to prevent overflow and pressure loss under high-temp/high-pressure conditions. Ports mate directly with XCMG OEM hoses for drop-in fit with no modification, suitable for various XCMG host machine cooling systems. Available by batch with bulk inquiry welcome.
