It's Official - Jndroark - 05-20-2017

Hello All,

Picked up Coach 431 today and became it's third care taker.  Have dreamed of owning a coach of this caliber for 20 years. Drove her 350 miles home through heavy rain, high winds and road construction.  For someone that never has never owned or driven a motorhome before I got her home safe and sound.  It took 100 or so miles to get the feel of the road.  The coach drove like a dream.  Reading all the posts on this forum about all that could go wrong I was afraid we would not make it home.  What worried me at first was the water temperature gauge would fluctuate between 195 degrees and 220 degrees.  I kept expecting to see the check engine light to come on but it never did, and I quit worrying about this and just drove.  Is this normal?

Will post a few pictures when I discover how that is accomplished.

220 a bit high. Mine runs 215 tops unless I'm on a big hill pulling 20k

I could not correlate why the temperature was changing.  Speeding up or slowing down, uphill or down hill the temp would get to about 220 then slowly go back down to 195, stay there a few minutes then slowly work it way back up to 220.  This cycle continued for the entire trip.

Joe,

Welcome to the group.

The gauges are not very accurate. Do a search on this forum and also google for VMSPc. There is a way to read and monitor the same readings the engine computer gets. Most of us depend on this for our engine metrics.

Congrats! Now I'm wondering if the temp. gauge is kinda accurate, at least if it's registering the temp rising/falling then maybe it's reflecting the hydraulic fan cycling? You do have the series 60 engine? What about the Detroit readout?
I agree with Richard with getting a VMSPC and using that to interface with the engine DDEC computer.

Thanks, yes it's the series 60 engine, the fan cycling seems to make the most sense.  Is VMSPC the silver leaf system that I have read about?

I will re-read the thread about this interface.

Congratulations on becoming our newest Newell owner Joe & Darlene. Look forward to meeting you down the road.

yes, the vmspc is the silverleaf monitoring system that runs on a laptop.

on my coach, the high speed of the hydraulic fan kicks on at 205. this trip i pulled long steep grades going up the flagstaff from phoenix and through the mountains in general up to nearly 8000 feet and never got above 208 on my vmpspc. i dont even pay attention to the dash temp gauge anymore because it is so hard to read with any accuracy. in summer when it is well over 100 degrees, it might get to 212 or so.

when the high speed fan kicks on at 205, it normally cools it down to high 190's almost right away. unless i am pulling 28pounds of boost for an extended time.

Also the VMSPC can be set up to measure the transmission temperature which I watch more than the engine temp. On a long pull such as from Sacramento to Reno, the transmission temp can go as high as 250 without damage. If you search this forum you can see how several of us have set up our VMSPC. I use a 14" Asus tablet that sits in front of the dash gauges.

My first question is where do I find the connector and would you know if it is a 6 or 9 pin connector?
