Re: L98 coolant temps???? (My 95)
Yesterday with climate control reading 100+ and the AC on, I was running 205 on the highway and 230 waiting in the drive-thru. My L98 runs hotter with the AC on. Without the AC, I generally dont see over 200 regardless of outside temps.

Re: L98 coolant temps???? (My 95)
Let me give some more details of my cooling mods tho.
Fans (AUX and main) programmed to turn on at 180.
160 stat w/ 1/8" hole drilled
My AC condenser is beat to crap so air flow and AC cooling isnt that great. Im waiting till summer is over to consider fixing it.

It should run about the same temps at cruise as your 95. It does have a stock 195F thermostat though.
I have a 160 and a reprogrammed chip to make the fans come on at 195. My oil temps stay at about 200F, go up to 215F with the AC on. Coolant is always 15-20 below that.

You might also clean debris from between the A/C condensor & radiator and maybe replace the T-stat.
In those temps a lower temp T-stat & fan switch would be a benefit too.

Re: L98 coolant temps???? (65Z01)
I had higher than normal temps last summer, and I took it into "Tony's Corvette Shop" in Maryland. He had me come back over to show me all imbedded leaves that were in the V space between the cooler and radiator. Plus a red shop rag from the dealer. My radiator fins were clogged, then he showed me how, due to overheating, that the plastic sides of my radiator were permanently buldged and no longer a rectangle. I replaced the radiator, and no longer have coolant problems. :flag
