Steve, when I first drove the Z, in local traffic with no AC, the temp would climb up to 238* and then come down when moving. Switching to Marc's chip, without the AC, 217* is the highest I have seen, and 210* the highest with the AC on, it will usually come down to 203*-201* when running the AC.
I am satisfied with where the temps are, and I have no idea if the thermostat
has ever been changed.
That's the way mine was until I took it to Marc. I had him pull radiator and clean it, replace thermostat, and chip it among other things. I don't remember what temp thermostat he put in it - but mine hardly ever goes over 200 now no matter what... So maybe the radiator clean made a huge difference. That sucker was NASTY for having only 18k miles. The lower right third was caked with grease and dirt - Marc said the oil cooler lines has leaked and been replaced - but the oil got all on the radiator and they didn't clean that when they changed the lines. I made a debris screen to keep the bigger stuff out right after I got the car - but the rad was full of dirt and greasy junk...
