When an excavator runs hot, it runs short — overheating triggers shutdowns, accelerates wear, and risks engine damage. This radiator hose-lower 3089943 / zax450/zax460/zax480（di） replaces the original radiator with a unit matched to OEM coolant capacity and flow specifications, restoring full thermal management.

Why Choose This Radiator Hose-Lower 3089943 / Zax450/Zax460/Zax480（Di）
– Fin and tube geometry matched to OEM for correct cooling capacity at rated engine output
– Full-face brazed aluminium core — no epoxy joins that crack under thermal cycling
– Direct OEM mounting — no drilling, cutting, or bracket fabrication

Heavy-Duty Construction
– Aluminium tank construction: pressure-rated to 110 kPa operating, tested to 150 kPa
– Electrocoat corrosion protection on steel frame components
– Pressure-tested before dispatch — arrives ready to fit

Maintenance Tips:
– Use OEM-spec coolant at correct dilution — incorrect mix causes internal scale
