Runs hot

[Rammer77]

I know it's hot outside but this seems high? Not towing. I got a 6 inch lift on 35s. I was you uphill but still I'd expect these Temps towing

Ram 1500 2014 5.7

The trans temp is what I would be concerned about. What are you normally running temp wise?Maybe the 5.7 is different but I have the 6.4 and engine temp is usually 205-215 while the oil will sometimes get hotter it usually will match the coolant. Depends on if I’m in stop and go traffic. But that trans temp is way warmer than I would like in my truck. Before I installed the trans temp bypass block my temps would stay around 168-170 if I were towing but now they don’t go above 145-150 towing.

They have 203 stats, so temp ok, Oil always be higher, just yer tranny looks a bit warm. May depend upon the amount of miles and if tranny has ever been serviced. But yer temps are real close to my 2019 DT truck, straight 5.7L no E-torque in TX, and it is 105 here.

That isnt hot at all, on long trips hot outside oil will always be hotter then coolant, and your coolant is perfect. Oil doesnt take temp as fast as cooling system and doesnt dissipate heat as fast. When the coolant is 203 it means the engine temp is right where it should be. Generally speaking oil after 250f you can start thinking about pulling over and idling a down a bit so you don't warp the heads. Main thing watch cooling down fast, so if it was cold outside these temps would be troublesome. The zf8 operates hot by design for fuel mileage. Look into all of the deletes. That is a little hot, but I think that averages at 195f. I wouldnt be concerned with anything I see there. If you feel so motivated drop a 180 t stat as well.

If you ha e a ZF 8 spd transmission, don't worry about the trans temp unless it spikes above the coolant temperature. The ZF trans will run warmer than the RFE trans without any issues.
What kind of temp does the trans hold if your cruising about 70-75 on the freeway?

My Rebel, 5.7/3.92 on I think 33's (air ride), runs about that on coolant and trans from what I remember. Pretty sure I remember (haven't been watching the temps in a while) that all 3 on mine basically end up matched +/- 3 degrees once it reaches equilibrium.
