I have a 2015 Ram 1500 with the 5.7l hemi and the ZF 8HP70 transmission. Just over 90,000 miles.
I did both differentials fluid changes with Redline fluids, transfer case with Amsoil MV atf. I also removed the Mopar factory transmission pan and put the PPE pan in. I went with the Valvoline MaxLife. I did a second and third “drain and refills” to get as much new fluid into the transmission.
Also changed the motor oil with Mobil 1 5W-20 and Mobil 1 filter.
I also did a complete drain of the cooling system. then I removed the old thermostat, cleaned both surfaces, and put the rubber O-ring back in place, then bolted the thermostat housing back. Filled with distilled water and a quart of “flush”. Drove for @ 80 minutes, drained again. Filled again with distilled water and drove for 15 minutes, drained again.
I put a new Mopar 203° Thermostat in. I put 2 gallons of fresh OAT coolant concentrate (to mix with the 2 gallons of remaining distilled water in the block).
Today I ran the truck for about an hour at @ 65 MPH. These are my operating temperatures. Are these readings normal? We are currently in Florida.
