Re: Engine temperature on a 1995 U300 with Cat 3176

You can either call Caterpillar Corp (877 777-3126) or go to any Caterpillar dealer with your engine serial number and they can tell you what thermostat (Cat calls them regulators) you need. Cat recommends changing them every couple of years
If coolant change is coming due, that is a good time to change thermostat(s) as well.
