RV Overheating

I have a Class A 2013 Coachman Marada 29' and it overheats when going up a hill and then will cool off on level ground. It has a Ford Triton V10 engine. The dealership can find no reason for this to be happening. Anyone else experience this problem and found a solution?? Thanks.

how do you know it is over heating? Can you hear the cooling fan at all? The fan should engage at a higher level when engine temps rise.

Go to Harbor Freight and get yourself an infared heat gauge. Check the temperatures when it says it hot. Check top and bottom of the radiator, hoses, thermostat housing etc, etc, to determine if it is actually overheating or getting hot. If it is getting hot you should hear the temperature controlled clutch fan kicking in as you climb a hill. If it's not kicking in and causing a loud noise then that's the problem.

A 2013 should still be under warranty. Get it back to any Ford repair center.

Sorry your having problems.
A few questions .
Are you towing a vehicle ? Do you know your MH and toad's total weights ?
Has the operation of the thermal hub on the rad fan been tested ?
Can you hear the rad fan noise increase before the overheating occurs ?
When you say overheating , do you know what temp it's going up to, or is the gauge just going into the red ?
What are the outside temps when this happens ? Does it occur when temps are in the 70 or just when temps are higher?

Once again my slow typing rears it's head.

In addition to Skip's questions, does the transmission downshift and allow the engine RPMs increase as you climb the hill? Gas engines make their power at high RPMs, if it doesn't downshift or you put it in a lower gear, the engine may overheat since the coolant isn't circulating as fast and it's working harder at the lower RPM.

OK Bruce, I got the info; from your note; of 90> 100 both times the problem has happened. Yellow light saying reduce engine power.
How fast were you going ? and how many RPM in what gear where you trying to maintain speed ?
If you are towing , and are over GCVW rating these are the type of problems that will happen.
Don't ask me how I know this .

Has the dealer explained what they have found going on and what has been replaced? As much detail on what it is doing and a history may help with this issue.

Get a Scan gauge II or something similar. It will display actual engine temperature the computer is seeing. Don't trust your dash gauge, it is not linear. Maybe your not overheating.
