Getting hot on the highway with the AC on.

200 is not hot! Not even close
240 is hot
Today's fuel likes 195 degree thermostats
190-210 is nomal
Stewart high flow t stat works well
Street cars require a thermostat not a restrictor...
Restrictors are for race cars.
Thermostats provide stable operating temps and proper flow.
Running the engine too cold [below 190] accelerates wear, contaminates the oil prematurely and it will not run as well as is should.
I have no need to prove anything to all you experts.
I will stop helping the uninformed any further
Well you’ve certainly stated your opinions well it’s clear to see. You make a great case on all your points. :rolleyes: And to think that if everybody only raised their overall running temps from what? 180? to say 195-210? that everyone’s setup would run even better! No if ands or buts!!! It’s a given, today’s fuels and all don’t you know??!! ... ....Yeah, total:bs_flag:
