FAQ 

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

Q2：What should be noted during T/C 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 T/C radiator damage?
A3：Cooling fins blocked by dust and debris; internal corrosion from deteriorated oil; impact collision; weld fatigue crack from long-term vibration.

Q4：Can leaking T/C 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 T/C radiator during daily maintenance?
A5：Check radiator surface for oil leakage and fin blockage, monitor oil temperature gauge reading during heavy load work.

Q6：What failures will a failed T/C radiator cause?
A6：Transmission oil and hydraulic oil cannot dissipate heat normally, oil temperature rises sharply. Oil thinning leads to poor lubrication, accelerated wear of torque converter and hydraulic pump, serious transmission breakdown.
