Given its critical role, the radiator requires regular maintenance:
Regular Cleaning: Keeping the external fins free of dirt, dust, chaff, and bugs is the single most important maintenance task. Blocked fins are the leading cause of overheating.
Coolant Quality: Using the correct Cat Extended Life Coolant (ELC) and maintaining the proper mixture ratio prevents scale buildup and internal corrosion, which can insulate the tubes and reduce heat transfer.
Pressure Cap Inspection: A faulty cap that cannot hold pressure will drastically reduce the system's efficiency and lead to coolant loss.
This 335-5459 radiator is used for 336E excavator.
