Re: temp question (vrodri3978)
I freaked when I saw these temps the first time too... for some reason they seemed high, but they're within operating range. Just to triple check everything, let your car idle till it goes passed 225 or something. Then turn AC on... it forces both fans to come on, and temps should drop about a minute later... this just makes sure fans are working ok. you can also hear them...

Re: temp question (vrodri3978)
If you sit and let your c5 idle the water temp will climb to 230 and the fan will turn on until it comes down to 200 to 210. The fan will then shut off and the whole cycle repeats itself. Generally speaking the C5 will run at around 200 degrees of water temperature if the car is moving at normal speeds. Again, if you sit in bumper to bumper traffick or at a stop light for a period of time the water temp will build until either you get moving and air is forced through the radiator or the fan comes on.

Re: temp question (vrodri3978) part 2 of question
also, should the high speed fans spin fast? it seems that they blow fast when the ac is on but when the ac is off, the fan turns slow.

Re: temp question (ifeeltheneedforspeed)
I have a question.... I just got a 3200vig installed and the shop went into the computer and firmed shift points, adjusted rev limiter and set my fans to come on earlier, keeping the car under 200 degrees when operating, maximum 205 unless the car idles some, then it probably will get to 230. Since where I live is fall/winter and the car takes awhile to warm up while I first start driving it, will this slowly damage my engine? I try to keep the rpm's under 4000 untill it warms up

Re: temp question (mark b)
My '99 Coupe used to operate at the same range & at first I thought it was normal too. But when I had a recent full check up it turned out I needed the following:
1- A set of new coooling fan motors
2- New top & bottom radiator hoses.
Total of around $ 268. You Might want to check it out since our babies are a little old parts may start to fail.
