i have a 2012 ram 1500, 5.7 hemi, 3.55 ratio, was wondering what the normal temp is for towing 6500lbs tt. what is hot temp, and what temp do i start getting concerned?
Hi temps drastically shorten fluid life. If you run at 250 but change the fluid every 15000 miles you would be OK...Mine runs about 150 empty, 175 towing and will get to 200 on a 90 degree day stuck in traffic. If you are seeing temps over 200 on the highway, the potential is there for 225+ which IMO is too hot and you should be looking at an aux cooler.
