Clark 15k regulator freezing up

Hi guys brand new here looking for some insight on why this might be happening to our lift. We've replaced the regulator which didnt seem to fix the issue replaced the coolant line, because the previous one had was all blocked up with a bunch of gunk, but the issue still persists. Could it be the water pump? Any feedback would be greatly appreciated.

When that happens it is a coolant flow issue
First check your thermostat in engine as the lift is running make sure you have circulation in system
Also check the thermostat on the vaporizer
That is the pipe that screws in on the top
If you have a bad water pump the lift its self will overheat make sure you have flow

You can take the thermostat
