• Premium 3003 aluminum alloy with excellent thermal conductivity, fast heat transfer and reliable hydraulic cooling capacity.
• Vacuum brazing integrated connection between fins and flow channels, solid structure and low risk of internal hydraulic oil leakage.
• Dense wave fin design maximizes heat exchange area, delivering strong cooling performance within limited installation space.
• Optimized internal runner layout reduces flow resistance, minimizes pressure loss and stabilizes hydraulic circuit pressure.
• OEM-level dimensions and hole arrangement, fully match original vehicle mounting position, simple installation and replacement.
• Independent hydraulic cooling design, separated from torque converter oil circuit, avoids mutual heat interference of two oil systems.
• Outstanding vibration resistance, can withstand sustained mechanical vibration during long heavy-duty loader operation.

FAQ 

Q1：What signs mean the hydraulic oil radiator needs replacement?
A1：Oil leakage from radiator, severely damaged cooling fins, rapid hydraulic oil temperature rise under heavy load, abnormal hydraulic pressure, heavily clogged core.

Q2：What should be noted during hydraulic oil radiator installation?
A2：Clean pipelines and radiator before installation, flush hydraulic circuit; align mounting holes and oil ports, tighten bolts evenly, check pipeline sealing after assembly.

Q3：What are common causes of hydraulic oil radiator damage?
A3：Cooling fins blocked by dust and debris; internal corrosion from deteriorated hydraulic oil; impact collision; weld fatigue crack from long-term vibration.

Q4：Can leaking hydraulic oil radiator be welded and reused?
A4：Not recommended. After aluminum core repair welding, structural strength drops, and re-leakage easily occurs under oil pressure and vibration. Better install new radiator.

Q5：How to inspect hydraulic oil radiator during daily maintenance?
A5：Check radiator surface for oil leakage and fin blockage, monitor hydraulic oil temperature gauge reading during heavy load work.

Q6：Can this hydraulic oil radiator fit other loader models?
A6：This hydraulic oil radiator is custom made for ZL50G/ZL50GL. Overall size, oil port specs and hole spacing are exclusive. It cannot be fitted directly on other models without modification.
