chipper shut down

Your coolant temp should never reach 220 with a 160 thermostat. Most likely you have a clogged radiator. Do you use a window screen in front of the rad.? The reason its shutting down is beceause its equipped with a "murphy" failsafe system which monitors temp and oil pressure and will shut down if the engine operated outside of set parameters. If you still have problems give Northeastern a buzz they can help you out.

Clogged radiator, bad water pump, bad thermostat, inproper install on new thermostat all possible cause of overheat. I would not run the unit until problem is resolved and temp stays in normal range 160- 180. I suggest changing the oil in the unit ASAP also, motor oil breaks down quickly in a overheated motor and can lead to worse problems. Welcome to site and good luck.

Dude - if you are at 220 you are overheating - plain and simple. Check into the usual suspects and you should be able to cure it...

you may have air lock. it you introduced air when you worked on the radiator system it may have an air lock that prevents the thermostat to open but still registered an overheating engine. this happened in my truck a few months back when i changed the water pump.
