Temp needle past 220
Today it was 63 degrees and my 2002 C5 base was getting hot sitting in traffic. I was stopped for about five minutes due to construction with the engine at idle. The temperature gauge was getting close to 240 degrees. Once out of traffic the needle faded to around 200 degrees. This doesn’t seem normal. Suggestions?

If it climbs up that high you can put the heater on full to bring it down.
There's a Tractor Genie right angle air and water wand you can use to clean out the rad fins.

Clean out the radiator like others suggested, a good preventative thing to do, also check the coolant level. Same thing was happening to my car a few weeks ago, and after cleaning and adding coolant, my temps went back to normal. I did check the fans also and they were working.

It worked the treat for me, blowing butt loads of plant detritus, dust and other crap out of my radiator.
I hooked it directly to my garden hose, using a shutoff valve, took the top radiator mounts off, and scooching the rad forward a couple of inches, I was able to slide the angled wand with it's side-facing holes to shoot several streams of high-pressure water and blow the crap out the front.
My car is 25 years old, and a fair amount of stuff, leaves, pine needles, tumbleweed remnants, etc. was blown free.
No escalating temps for me after the treatment, and I was routinely going over 220 in traffic and in drive-throughs.
IM or email me if you are interested in my offer.

And you can install a Sac City CoolIt. I have had one for about eight years. It allows you to call up high fan from the cockpit with a fob. I use it when in traffic or coming off track after last lap.

I made my own cleaning spray wand and will rent it to you for the low, low price of free - just pay the postage both ways.

Cleaning the radiator of debris is good, but lets not forget the fans dont even come on low until 220. Thats not really hot for these cars.
