What to do if steam is emitted from the radiator of my CASE CONSTRUCTION Excavator?
- KKevin HarrisAug 3, 2025
If steam is coming from the top of the radiator and the coolant level warning light is on, several issues could be the cause. First, ensure the coolant level is adequate and check for any leaks. Next, verify the fan belt has the correct tension and adjust if needed. A dirty cooling system can also cause this, so flush it out. Inspect the radiator fin for dirt or damage. Also, make sure the radiator cap is tightened firmly, and if not, try replacing the packing. If these steps don't resolve the issue, it may be a thermostat or cluster defect, and you should contact your authorized dealer.
