Q&A

-
-
Q1: What are the main signs that my CAT 323 excavator radiator needs to be replaced?
-
A: Key indicators include frequent engine derating or overheating alerts on the touchscreen display, visible coolant pooling beneath the side cooling compartment, or extensive fin erosion/crushing caused by high-pressure washing or airborne jobsite debris.
Q2: Can I clean this radiator if it gets plugged with dust on the jobsite?
-
A: Yes. Regular cleanouts using low-pressure compressed air or water are recommended. However, because Next Gen machines have tightly clustered cooling packages (radiator, oil cooler, and charge air cooler stacked together), debris can easily become trapped between the cores. If the engine continues to run hot after an external wash, an internal blockage or scaling may be present, requiring a replacement core.
Q3: Is it necessary to replace the thermostat when installing the 508-6290?
-
A: While not strictly mandatory, it is highly recommended. A sticking or old thermostat can prevent the coolant from circulating properly through your new radiator, rendering it inefficient. Always flush the cooling system completely and refill with fresh CAT ELC (Extended Life Coolant) to prevent internal cavitation and scaling.
