Four years ago I replaced the thermostat and temperature sender on our Westerbeke 8kw genset.
Not having much use for a genset at that time I simply would run it until it warmed up and then shut it down, just to exercise it once in a while.
Not that I actually "need" it, the temperature gauge wants to hover around 140, then quickly jump to 180 before slowly working it self back down to 140. This cycle keeps repeating itself.
Checking temps on the unit itself, the top of the thermostat housing changes temperature in step with the fluctuating gauge, going from about 150, up to 180 for a few seconds before dropping to 150 for a while. This pretty much tells me the gauge isn't lying to me.
The exhaust manifold is at a constant 190.
I have tried bleeding air from the top of the thermostat multiple times with no effect and I seem to be at a loss on why this thing is running cool most of the time (or maybe it's not).
I failed out of genset school.
Does anybody have any ideas?
