I have a 2020 ram 5500 6.4 gas with a boss 10' v plow both new 4 months ago. I am new to this forum so sorry if this has been discussed but I could find any on it.
Truck has 6,000 miles. If I take the truck on the highway it will go up to 250-260 degrees, temp light comes on but only last 30 seconds and rapidly drops back to low 200's. Also with the plow on the truck it won't down shift a lot of the time. I can hold the pedal matted and will only go up a few rpm and not shift out of 6th gear on the highway until I manually do it. Also usually always starts off in 2nd gear.
I have had it in the shop 8 times already for this and other small issues. The dealership is telling my the truck works fine with the plow off and under 40 mph. Ram says in its manual says not to go over 40mph with a plow attached. So Ram is telling me that the truck is working as its supposed to and there is nothing they can do but try a smaller plow!
I own a landscape company and need to go on the highway to get to my accounts. Has anyone else come across this issue and have any help! This truck has a pcm controlled thermostat and I believe this is the issue but since no codes they say everything is normal this has become very frustrating and worried about future damage by constantly overheating my truck.
Thanks,
Tom
