Overheating at end of trip

Made it 2,500 miles and was only 3 hours from home but after topping up with diesel I got an engine warning and stop engine, high coolant temp. No visible leaks, coolant level good.

Shut her down and let things cool off. Started up and temp slowly rose to 210. Stayed there awhile and then slowly climbed higher. Got the warnings again and shut it down.

Called CoachNet and got towed to San Antonio Freightliner. They have an RV division and will be looking at it after the holiday.

I hope itís just a sensor or something but if they have to open it up, what else should I have them do? Iím guessing the radiator has to come off so I thought maybe do some other maintenance at the same time?

2014 Palazzo 36.1 38,000 miles.

Thanks in advance.

Friend of mine had the serpentine belt fail and that also ripped the wires to the electric fan. Yes, radiator had to be removed. If it is the serpentine belt, you may want to replace the idler pulley. Search the forum about serpentine belt failures.

Thanks.

Just had the alternator replaced prior to this trip, had the belt replaced just in case at the same time. I would have been immediately suspicious of the belt but it worked great the first 2,500 miles of hot and hilly driving.

That doesn't mean that the belt isn't shreaded now.

ALWAYS look where the last guy worked, even if it was you.

Update: looks like the A/C compressor froze up hard and threw the belt.

Hopefully I can get a new compressor quickly. I carry a spare belt but it wonít do any good with a locked up A/C.

Anybody know if this is a quick remove & replace or is it major work to get to the compressor?

It might not apply to your rig, but I have seen people post about using a shorter belt to bypass the AC compressor.

Good luck.

Thanks, thatís not the issue but will be having some preventative maintenance done while they have her opened up.

Itís not an emergency, I donít need to bypass it. But thanks for the info I will look into that for the future.

Anyone know if the access to the A/C compressor is from the rear or do they have to open up from the top?

If it’s from the top I’m assuming it’s access from the rear bathroom floor. Any tips on that process or other things to do while it’s open? How about adding sound deadening like dynamat ?

Apparently you can get to the A/C compressor from the side

Probably through a side compartment with a removable back.
