Wow, Wrong word ! Coolant Temperatures – Sorry.
Yes, you are right about that, what I meant to say was that the Coolant Temperatures
should be in the 210+ Deg. Range to make power.
And for your Engine running a 160 Deg. Thermostat, that is when it starts to open.
What Temperature is your Engine after a long run ?
There are a lot of other things that Contribute to Coolant Temps.
Long Runs on Hot Humid days, Traffic, Heat load from the Roadway itself, A/C, Auto Trans Heat being dumped into the Radiator, Thermal build – Can be the eventual “heat Soak” into adjacent Parts and so on.
I was trying to point out What you run for a Thermostat is not what your Engine Temp Gauge should read.
All good stuff, I thought I read thru it Carefully, Thanks Scott.
