APU busted top radiator hose and dumped all my coolant in middle of ATL a week ago. Nevertheless ordered a new hose put it in and now it’s getting hot and shutting down.
Turns out my APU cooling fan isn’t coming on. I unplugged it and straight wired it and fan works fine and unit ran as normal no shutoff etc.
I haven’t checked fuse yet but I will in the morning. If that’s not it figured it be the temp sending unit for fan. It appears to be right below the thermostat on back of engine. Any suggestions or clarification as to where the temp sending unit is.
It’s a Thermoking Evolution
