Mine ranges from 187 crusing on the highway to about 210 standing still, your temp should be just fine.

Read that thread...should answer any questions you have.

For all you Canadians.....................83-84 degrees is normal operating temp and all I've ever seen even driving WOT.

I am usally in that range but 90-95 isn't unusal.

i think over 230 is too high... welcome dude... where-a-bouts in jersy you from?

If you peak over 230 once in a while, it's ok. If you're over 230 consistently, it's not going to hurt the car, but it is a sign the system's losing its ability to cool the engine. If it has been a while, get the system flushed and re-filled. Over time the coolant will break down and won't transfer heat as efficiently.

i just got mine filled, and they put in the green coolant instead
i was pissed, so i went and bought a bottle or Water Wetter

There's no difference in performance between the green and the red / orange / whatever color they put it. You just can't mix them. As long as they flushed it first, then re-filled with green, you're good to go. I had my Pontiac flushed and filled with green after my radiator, heater core, and water pump all had to be replaced in a 1-year span. No problems after that, except the heater core going again, but that was due to a bad install from the shop.

really?
then why do they put in the Dex-Cool?

i have had mine get up to about 230 max when i was sitting idle in the staging lanes at the dragway but as soon as i went down the track it droped back to around 190 where it usually stays

Who knows? Marketing, maybe? I have not seen a single mechanic say dex-cool is better than anything else, and have seen several that say it's not. It's "supposed" to last 5 years / 150 k miles, and perhaps it does, but you still need to break the system open sooner than that and flush it. I supposed afterwards you can put the dex-cool back in rather than change the fluid out, but it's not like 15 bucks of green stuff every couple years it going to break the bank, anyway.

^^^ Last time I bought Dex-cool, it was ORANGE! I hover in the low 190s while driving in the city.

Mine has been as high as 223 with the AC on and 105 outside. It did`nt seem to hurt anything

Likewise...I was referring to regular antifreeze as the green stuff.
