My friend got me the motorhome,. It is a 1986 Pace Arrow with a Chevy 454. It started right up without hesitation, It ran great as the seller was talking and we said our goodbyes and off I went in the motorhome and off my friend went in his car. The gauges are jumpy they read nothing and then full tank the half. it read low temp then real high. a lot like my Holiday Rambler. But the Holiday Rambler has after market gauges that work like they should so I figured that the old GM gauges were not good. Well it over heated and I noticed that the belt fell off the alternator and water pump. The seller came out and helped me out on a new belt that I got at an auto parts store. I was driving to go back home. and 4 miles later over heated again,, then belt was off again. what can casue this and how do I fix this??? thanks so much for any help.

The idler or the water pump may be either falling off or frozen and the only way to tell is to look at it.

I will haveto go look at it this week. it is sitting at Ellis park near Henderson KY. I don't know if there is a motorhome repair place around there if so I may have them look at it.

Well, if you can loosen the belt, then check the waterpump to see if it turns, that might be the answer..

Yes the water pump turns very easily and it must be working as the water temp was at a little below middle mark, then it got hot voltage when down and the belt was off,,,,, alternator spins freely couldn't find the idler as it is tight in there and just wanted to get back. I hope it is something simple.

Does it have a serpentine or v-blet?If it is kicking the v-belt, check for proper alignment of the belt on the pullies.

Another belt throwing problem with engines of that vintage . Smog pumps!

These were sometimes removed as they had a tendency to seize !

Do You detect any kind of squealing noises while the engine is running?

Either something is not turning or the pulleys are out of line for some reason. You will have to check it out. Only other thing is the belt is routed wrong.

Make sure the pulleys are tight on the shafts. I had an alternator installed and the tech did not get the pulley tight enough. It eventually became loose and started to spun on the shaft and wallered the hole out in the pulley and let the belt go.
