Re: Onan shuts down under load without shutdown codes

Hi Bill,

I have a problem with generator overheating (106 dC) coolant temperature . Sea water exhaust temperature up to 80 dC. Have checked impeller (it is new) , new oil, fuel filters, new oil. Before service at 1000 hours it was working ok. I am thinking that thermostat might be a problem. Or should I concentrate on seawater cooling system?
question is if thermostat fails( it is open, no flow od coolant) is the seawater system strong enough to cool the engine on 80 dC? In my generator this is not the case.

thank you.
