With water cooled engine, will it run longer with the doors open? Is the fan belt tight? Is it blowing coolant out of the overflow tube? Is the radiator clean, not restricted?

the gen set is running at normal temp when it turns off yet its code shows over temp shut down this should only occur at 103 degrees and not 85 which it runs at we have by passed the temp sender and it has made no diff

Could the compressor overtemp sender be cutting off the unit, not the engine overtemp?
