Here is the scenario: brand new unit (Fleetwood Expedition 36M), ~ 2 months since delivery. Genset is a Cummins Onan Diesel HDKAK. 30 hours on the genset (two trips, one to the northwoods - cool, needed to recharge the batteries, the other to the south - hot, needed to run it to power the AC during the evening and while driving). since the unit is brand new, I assumed that everything was ready to go, and did not check (actually, did not know that I should check - sorry, newbee..) the fluid levels in the genset. After reading the recent thread on "how long can one run the genset", and many posters recommended checking the **oil** levels, I decided today to check the levels in the genset.
When I checked those levels, the oil was fine, but the coolant in the overflow tank was **dead low** ... as in, BELOW the "lowest when cool" line, and when looking in to the tank, just above one of the ports (not sure whether the intake or oulet, but it is on the side of the tank).
Here is the question
: do you find that when you run your gensets over a timeframe of ~30 hrs (esp. during hot highway driving), do you get significant coolant loss on this order of magnitude??? The other options that I figure are that the genset sat for quite a while at Fleetwood pre-manufacture and lost significant coolant volume, OR I have a leak that I need to keep an eye out for. What does the Wisdom
of the Website have to say????
(BTW, I mean that literally - I have always been very impressed with the breadth and depth of the knowledge that you all bring to bear here: I do hope that at some time I have the chance to meet some of you!)
