Re: Oveheating or NOT???
To me, "overheating" is
1 - actually boiling over.
2 - temperatures continuously climbing when not under load, well over cruise temperatures.
200 is not hot, but if you have a 160 thermostat in, and coolant goes to 180, then when sitting idling, starts creeping up to 200,210,220, that is a problem.
Before I swapped out rad, and made a shroud, I had a 160, coasting down a hill gauge would drop to 160-170, then idling in traffic creeping in drive, it would keep climbing, and who knows if it ever would stop. Never boiled over, but it got HOT, well past 220. This is all on a electric SW temp gauge with sender in drivers side of intake. My FiTech reads maybe 15 lower, on the passenger side of the intake, I assume due to the return from the heater core cooling down that side.
If you have a steady temperature that isn't too hot, like say 5°-10° over thermostat value in the rad, I would be happy with it.
