Bobcat 553 running hot

[twoods5244]

I am a newby here and just purchased a used compact Bobcat 553 loader at auction and don't know a lot about the machine. I used it for a short time moving some dirt and when I cut it off, I could hear the coolant boiling. I do not see a temperature gauge in the cab and not sure exactly how this unit is cooled so I'm not quite sure where to start troubleshooting. Any help or advice?

I'd start by checking the coolant level, then clean any debris off the radiator and oil cooler.
