Where I am it tickled 100.And that’s if the gauge is even correct. I’m going off the original gauge which has a 210° line. Honestly, without the pusher fan, I’m sure it go over 210 and may or may not occasionally do that anyway. I’m just looking for a bulletproof cooling system. I hate running hot. Agree 210 is not that bad, but it was only like 90 here today.
By the way my big rig runs 210-215 all the time occasionally hitting 220 then back down.
They run cleaner at those temperatures.
As long as the cooling system is good and keeps it there.
