Temp gauge question, couldn't find my answer by searching
So I did a search on temp gauge, normal range, etc. but didn't find the answer to this. I did find a thread that said 40* swing is normal but not where that 40*'s was, so I wanted to ask. I have three lines "|||" with 190* under them, mine runs when driving (and it is pretty cool here in KY now 50-60*'s ) right around the second or third line. When stopped it goes up to the edge of the yellow pretty fast, I haven't seen it go into the yellow, it just kisses it and then comes down when I start driving, I have also seen it come down on its own and am assuming my fan kicks in (but I can't hear over the beautiful exhaust note lol). Question is A) is that normal to kiss the caution range and second what about next summer when it is 90-100* in the shade, is that going to push it into the red or do the fans take care of it, do you just avoid really hot days where you can get caught in stop and go traffic? Thanks guys!!!
I can only speak for mine, and for what I've read on the forum. Mine runs consistently between 190 and 210 (according to the gauge), pretty much regardless of the outside temp. I bought it in Northern California, and immediately drove it to Central Arizona in 80-90 degree temps, and it ran @ 195-200 the entire way.
These cars warm up quick, and like most fuel injected engines, are programed to run warm. I wouldn't worry about the conditions you described. Just make sure your cooling system is full (not sure if you have the same overflow bottle in the passenger side front facia that a Gen II does, but a Gen I guy will let you know), monitor the guage, but don't obsess over it.

The year does matter. '92 -early '94 Gen 1s had slightly different yellow zone markings than later Gen 1s. '94+ cars all had a fender-mounted coolant bottle on the passenger side to check fill level. Early cars are more susceptible to trapped air pockets in the system and require a very aggressive "burp" procedure to be performed, but all Gen1-2 cars need careful burping to minimize steam pockets in the system. If you have an A/C car, then it will run quite a bit farther to the right side of the gauge than a non-A/C car on very warm days - occasionally illuminating the red light in slow traffic. Not always serious, but definitely something to keep an eye on.
It does appear from the symptoms described that you may very well have air trapped in the cooling system. Do more searching on the subject of burping.
96 GTS - some exhaust, brake and handling mods.
Its a 94 stock RT10. Ok, I'm going to look at Coolant (maybe I just don't have enough?) then burping. It NEVER has gone into the yellow just up to it before coming down. How high does your all's go in stop and go traffic????
My 94 would run into the yellow, upgraded my fan to the later style and that made it run cooler. From what you described though pretty normal for a stock GenI, they changed the gauge half way though the 94 year and got rid of the yellow mostly to stop people from bring it back to the dealer for "over heating" because it was running in the yellow.
Ok, well I have a little more info now after speaking to a local viper club guy that is awesome. I opened my pressure cap and couldn't see the coolant, so I put about 3 cups in and it brought it where it needed to be. Second I located the overflow bottle in the front facia and it was bone dry, so I thought "hmmmm" but went ahead and started a small fill there too, well I've got the dreaded "screw puncture". So I flushed it with water and blew compressed air through it and used paper towels for an hour to get it as dry as possible and then filled the hole with sealent as a temporary fix. Hopefully it will hold I'm not going to fill it until tomorrow afternoon to give the silicone plenty of time to dry. I will try to burp the system tomorrow and see if that makes any difference but if there was no "yellow" mark I wouldn't think anything of the temp, so maybe everything is ok, I'll report back, thanks guys!
Also in that thread, the pic where he shows the red line where the fan kicks on, I went out and looked at my gauge and that "seems" to be right where my yellow range starts, so that would appear to be normal then as his travels that far before fans kick on right?
