I have a kubota 10k generator from Wrico and is water coooled w/electric fan. I've been wondering what is the normal water temperature for the cooling system?

just off-hand I'd say 185-192 is acceptable to me....

I have a 10kw with 4cylinder Kubota from Powertechnology. It runs at 175-180. When it gets to 225, it shuts off. Usually 175 is closed thermostat; 185 is fully open thermostat; above 185 and your over heating. Good Luck, TomC

I'm looking for something to "add on" to my generator to shutdown when it over heats. Anybody have a suggestion where i can get it?

It should already have one is the shut down solenoid mounted on the side of the injection pump ?

I'm looking for something to "add on" to my generator to shutdown when it over heats. Anybody have a suggestion where i can get it? There is a temp sensor on my bus engine - it closes (ie. sends a pos. electrical signal) when the engine coolant reaches 95 deg C (about 202 - 204 deg F). Depending on how your generator is controlled, it should be pretty easy to set up a control to shut it down (NC relay that opens when it sees the signal from the temp sensor to open a ground, or a NO relay that gets pulled in to close a fuel solenoid etc.) Unfortunately, I have no idea who made that sensor or what it's called and the company that made it is probably like every other British manufacturing company -- bought up by a Singaporean conglomerate 22 years ago and pretty much disappeared from view -- but there should be a N American made equivalent. (But isn't there a control like this built into your generator anyway??? There is both an overheat and a low-oil-pressure shutdown built into my Onan.) |

I'll check later today. Before I go "chasing my tail" the temp on my wrico generator goes to 220 degrees f. Will air in the cooling system cause this and how to fix? It has a electric fan blowing. I have a new thermostat ready to switch out if needed. Anything thing else unusual that would cause this? The generator has 10 hours of run time. |

http://www.wanderlodgeownersgroup.com/forums/showpost.php?s=85d5f97a2115f2cdc9de99bbe036e537&p=167306&postcount=10I guess they all over heat...info from Kubota excavator 4cyl hoe....I hope they are talking Celcius......after all they are metric....  The new coolant temperature gauge helps prevent the engine from overheating by keeping you informed. Located close to the control levers, a warning lamp lights up when the coolant temperature rises to 115 degrees, and turns off when it falls to 108 degrees or below.

I replaced the thermostat and when I refilled the engine and radiator with coolant it burped air out. Now I'm not sure what fixed it: the new thermostat or burping it...LOL.

You can check the old thermostat in hot water and find out!

Hello All. I spent a lot of time worring about the temp of my genny as it is air cooled (Yamaha EF3000iSEB enclosed in a below bus box). I finally came to the opinion that the most important temp measurement was that of the oil. Generally speaking, 220 degrees F is about the upper limit for motor oil and as long as the oil is happy the genny will keep running. 220 degrees F is not hot enough to be a problem with wiring or most insulation so as long as the oil temp stays lower than 220 degrees F all should be OK. By using thermocouples I set my genny up to ground the spark if the oil temp reaches 200 degrees F. So far, so good.
