Well I guess I was half right  :D

Check the weep hole on the back of the water pump. It will slowly leak enough to cause what you've described, if the pump needs service. Fwiw hth

I tested all the sensors and skinner valves all appeared to be working as designed.

The wires had been repaired on some of them, I redid any questionable connections.

It continued to shut itself down after a few minutes.

If you were sitting in the driver’s seat and looked real close, it quickly flashed the overheating and low oil pressure indicators at the same time while it shut down.
 
The temperature on the dash and on the gauge in the back never got over 180, the oil pressure was right up where it should be on the dash and the mechanical gauge in the back.

The coolant was low, I looked at all the sensors on the Bus and in the manual, I could find nothing that indicated there is a coolant level engine shutdown.

None the less, when I added approx. 2 gallons of coolant the issue went away, I ran it for over an hour and drove it for 20 miles, no Issues, very strange.

So there must be a coolant level shutdown somewhere I cannot find, probably a good thing.

Now I need to figure out where the coolant is going, last time I checked the coolant level was when we did a 500 mile trip in September, I had not checked it when we got back, I don’t see any visible leaks anywhere and there is no water in the oil.

Niles500,

It is definitely a Mechanical engine, not a DDEC, probably the last of its kind installed in an MCI, in 89 you could get it either way.

Sometimes when I see some of the things you can do with a DDEC I wish I had one, but most of the time when I see the issues that can occur because of the DDEC, I’m quite happy with my mechanical engine.

Although he said mechanical, I'm assuming an '89 TA is  DDEC; May be wrong

Flying J's are not quite the same since Pilot bought them. Out East at least, they did away with the buffet and put in Denny's. They used to have fuel discounts for FMCA members.

I think the covers are ugly myself,Chad can give the owners information he had it on consignment ,it  has a HWH  slide ,the smaller ones are from Prevost,I forget the milage but for a conversion it was high

I like filling with small nozzle's ,no foam, time to walk around and do checks and clean the windshields and walk the pets ,plus they are cleaner.I liked the older Flying J's you could get fuel,dump you tanks,fill with water,and buy propane if needed all at the RV island with out moving and there was no dump fees

I used to use Flying J's all the time when I had my 36' Fleetwood Discovery with a trailer, as everything was right there. However with my 40' bus and toad, I am afraid to use them, as frequently people park in the spaces in front of the RV pumps and I have always been concerned that I would not be able to get out of there due to so many cars in the way and haivng a difficult time backing up with the toad.  But I haven't used Flying J for several years, so maybe they aren't so bad for a 40' bus with a toad.  Not sure.

Chad had it for sale at Premium Coach in Mesa AZ ( Gilbert), the covers was added he talked about removing it when I was there it comes off to change the tires on the tags ,I think it was converted by Millenium in FL for a motor cross bike rider, they can call him he may have more information, it has a huge side out that was added one would not want to buy that piece of glass, the painted Stainless siding why they did that is beyond me it takes away a lot from the bus

Thanks for the info Cliff.  He did say it was converted by Millenium and did mention the bike rider. He seemed to think the bus was well known, but he himself doesn't know much about it.  I thought maybe the tire covers came off. I am not sure why they would have added that. I don't see that it adds to the aesthetics of the bus.  I assumed the slider was added.  A friend of mine had a slide added to his Prevost that looks very similar. With his bus, you wouldn't even know there were slides in his bus, unless you saw them out.

It only takes a time or two of turning the tractor too sharp with the wind blowing, before you learn to pay attention to how strong the wind is and which direction it is coming from.....btdt. :)

Check the skinner valve on the back wall ,they will start bypassing the air and shut down,it easy to check the shut down syatem,on the right side of the engine there are 2 senders on the t-stat housing 1 for temperature and 1 for high temperature shut down disconnect those if it shuts down it is the skinner valve on the rear wall ,be sure the rear start switch is in the right positions too if not when it builds air pressure it will shut down .The low water sensor on the surge tank will not shut a non DDEC engine down in a MCI that I know of but you can bypass it with a paper clip to check it,if it has one .most just have the sight glass to check the coolant level
