I'm curious about the operating temperature for our super coupes. The temperature gauge on my 93 SC has NORM in the center. I drove a good two hours the other day when it was 90+ deg. outside and the temperature needle slowly creeped up to M and slightly past when stopped in traffic. I don't know how hot this is, but it seems hotter than I'd like to see... When I was cruising 70mph on the interstate, the needle didn't go past R.
Watching the temperature gauge, I think the thermostat opens when the needle gets between N and O because the needle will drop down below N, and the fan doesn't kick on until it gets between R and M. Does this sound right?
I don't know for sure, but it seems like the fan cycles on and off, because when it got a little past M, the needle started to go down between R and M, then would creep back to M, and slowly go back down...
So my question...Is this temperature condition normal?
How hot is M ?
I have only seen the temperature go to M when the outside temperature is 90+.
When it's below 80, It hardly goes past O.
The car has a fairly new radiator, the overflow is working fine and coolant level is where it should be, doesn't use any coolant and the engine is stock - runs perfect.
