water temperature problem on a 06 wabash carrier ultra xl reerer unit

Dallas has been experiencing pretty hot temperatures lately. We are on the edge of it ourselves.

Whatever coolant mix you are filling your unit with, it should come out to be capable of carrying a certain temperature capacity before it overheats.

If it continues to be a problem get a list of factory repair locations for your unit and show up there. They will be able to dig down and get to the root cause asap and fix it because you have to have a trailer that works in reefer. Or find another one that will work.

 

Water boils at 212F. Antifreeze 50/50 mix at around 223F or so.

As long as your radiator fan comes on and drives the temperature down when your water temperature gets above 210 or so, I don't think you have a problem.

If the radiator fan does NOT activate at high speed to drive the temp down, then you need to have your radiator fan sensors and controls checked.

 

That is hot is it running in the green zone or red? If the fridge motor is old it will start to feel really hot days if you go somewhere and the outside temps are cooler is it still running really hot? If its not then you'll know it was simply the outside temps effecting the cooling capacity. If its still running hot even if your now in a cooler climate then you might have to get it checked out, the other thing is clean the grills on the radiator if there choked up with dirt and debris that can cause it to overheat.

 

And I was oblivious and thought you were talking about truck radiator water temps.

 

I've had reefer units of all shapes and sizes over the years. If it is very hot outside, 206 would fall under being "normal-high" to me, especially in an older unit. When it falls down to 80 degrees outside, if it's still running that hot there could be a developing issue.
