392 running temps

[JJMalone]

I'm curious what temps your 392 is running? Mine is supposedly getting shipped this week. My stock '20 JLR 3.6/auto runs 192-205 normal highway driving. It runs up in the 220s Loading engine with fairly steep offroad hills when it's hot out and cools pretty quick when fan switches on. I run Redline Water Wetter and believe most of their hype. I believe the 3.6 cools well but they carmakers run everything hot these days to improve emissions. I'd like my coolent and oil temps to never go over 200.

Mines been running about 20 degrees hotter than my 3.6, around 220-230 in various driving conditions (oil pressure quite a bit higher too at 30-50ish).

The biggest difference I’ve noticed is the heat coming off of the firewall and the front floorboards. Big increase from the 3.6L. The a/c struggles to keep up sometimes.

Probably more heat from the exhaust and that and it uses 1234yf for refrigerant, probably cools a little less than previous 134a systems.

Interesting. My AC works better than my 20 Rubi did. Temps are right where they should be. Under 200 is NOT efficient.

This was taken after a very short pull in the hills. Actually runs a little warmer. Still no issues at all though. Pulling a small popup in 90* is well within what I consider optimal.

Almost identical temps for me after a 4+ hour highway drive in 90+ degree temps. Very little movement in temps across the board.
