Wallace, I said when I left the USAF in Feb.1971, that I wouldn't be caught north of the Mason-Dixon ever again in the winter. That was after spending 3 winters in Ma., and myfinal onein Alaska. Has worked well until this winter, now this warming thing that folks keep talking about has moved partly to Canada, and left N.C. in the deep freeze. Think I might have to move tomid Fl. or southern Tx. I have lived here all my life, and am getting to old to put up with extended cold spells. Is Livingston a good place to spend the winter? I have heard that a lot of full timers winter there. My daughter lives in San Antonio, but will be vacating there in a couple yrs. at most, so we would have no reason to be there after that. I know that you folks in Tx.,Ok., etc.have been putting up with cold weather as well. I just want to know , who is holding up thewarming spell? George Burke 1977 FC31 Charlotte

Mike, I have two engine heating sources. One is a block heater which is turned on under the kitchen sink. The switch above the drivers left side is for the AH system. This is as I understand it from Ralph; I claim no personal expertise whatsoever. Nothing was said to me about doing anything other than turningon the overhead switch;i.e., no need to otherwise activate the AH.Best solution, stay south of the Mason-Dixon line as much as possible.

So I guess what you are saying is that when you use the engine preheat the engine cooling system and the house hydronic heating system are hooked together and share common fluid when the engine preheat is used? Correct? Guess I should have flushed the house heating system when I flushed the engine and put in new diesel antifreeze. Never thought about that when I flushed the cooling system when we installed the new engine water pump this summer. Good thing I have not used the Primus, so the new antifreeze should not have mixed with the old green stuff in the hydronic system, correct? How long are you in Marble Falls for?

The preheat pump will work regardless if there is heat or not.

There is a pump, I think it is twelve volts that is behind my house battery trays. It circulates warm hot water / antifrezze mix to the engine and I think the hot water heater from you Primus or Webasto unit. I found mine this summer when I turned on the switch and heard it. > > Enjoying the weather in the Texas Hill country, above zero and no snow to shovel > > Steve Quandt > 1993 PT-40 > Iron Mountain MI > now in Marble Falls, TX > > --- In WanderlodgeForum@ yahoogroups. com, "mbulriss" <mbulriss@ .> wrote: > > > > OK, I have one of those how-to questions that is not answered in 'the book'. On my 91 on the far left topmost driver overhead dash panel, there is a black two position toggle switch labeled "Engine Preheat" - that's it, no "on" or "off" indication, no light. My question is: Is "on" when the switch is toggled in to the left side or the right side of the switch? What kind of electrical draw should I see on any of the gauges when it is on - *if* it is working? > > > > Normally, we try to stay out of such climates where I would actually need said switch, until this past weekend in the Texas hills where it got well below freezing. ;^) > > > > Thanks, > > > > Mike Bulriss > > 1991 WB40 "Texas Minivan" > > San Antonio, TX > > >
