placing a resistor inline will delay or stop the fan from coming on at all. The fan switch itself is called a thermistor. The higher the temp the lower the resistence.
If you are not satisfied with "a" there are two options. Change the temp sending unit (gauge)or change the temp sending unit for the (pcm)
It is possible that one of these sensors is near the limit of acceptable range.

My '99 tour runs right in the middle of the guage but it has been updated from previous years. I have to agree with the other guys with older 'tours- the guages are wacky and this has been debated for a long time now.
Don't worry, your 'tour is fine with the guage running where it is. If you want to check, take a thick rag an take the radiator cap off if you think its too hot. The water would be boiling if it is too hot.
I'm kidding about the radiator thing- that's pretty dangerous. If the water was boiling, your looking at a pretty severe steam burn.

Grate discussion guys. Here are the answers to a few of your questions/suggestions regarding my concern. (1) My tour is a 1996 LX. (2) My fan cuts in when the needle on the temp. gauge reaches ?A? and I presently have Red Line Water Wetter added to my coolant along with a 160 degree thermostat.
I note that both CONTOUR.DRVR & redhawk who owners of 99 tours do not have this problem thus supporting my view that it?s not a normal condition. Fuzzy has suggested changing the temperature sender unit which I think is a good idea, however, does any anyone know what unit would be suitable and whether the sender unit used in the 99 tour has a different temperature settings and if so can it be installed in the pre 99 tours and what?s the part number.

OK Guys, I have to thow in my two cents here. The only way to know if your car is truely overheating is by using a thermometer with actual gradations on it to check the temperature. The difference in gauge readings mean nothing really. I mean it's as bad as my old Diplomat with 'two notches past C'. As a GM mechanic I see a lot of people complain that their new Cavalier is running hot because the needle in the gauge goes to about 3/4 of it's travel in traffic. When you actually take the temp, it is usually around the 200-210 degree mark with my THERMOMETER (the gauge cluster is electronic and will display whatever setting the computer dictates). Anyway, the GM manual says that the cooling fans should not engage until 230 degrees. I thought this was very hot, but it is correct. The hotter you can (safely) run an engine, the more efficient it is. I have run these cars for 2 hours straight without the cooling fan engageing (sp?). The computer can, and will vary the engine temp through mixture control to keep it at an optimum temp. Remember, if the cooling fan kicks in, you are wasting fuel, which the government frowns on.
Anyway, sorry about the long post, I just felt I had to contribute.
The short answer is 'for the most part, ignore the gauge, unless it goes EXTREMELY into the hot side. It is not much more useful than the old "idiot lights". '

I mentioned in a thread similar to this one that my Zetec's gauge never rises above the bottom third of the gauge...and now that I look at it, it doesn't say NORMAL either...just C with a line over to H...

I don't know much about this, but basically i think this says that 98+ contours do not have this problem, being that they both have 99 contours. So basically, I'd say it's a normal for 95-97 contours, being your contour is not 98+. you yourself said that they started installing twin fans in 98+ contours. correct me if i'm wrong.

My gauge never goes past the first third of the meter. I tend to think my engine runs rather cold and rich. BTW, I have A single fan in my 98+.

You could aways run a bypass switch to manually activate the fan. ------------------ P.

OK guys I am convinced that I should leave well enough alone, therefore I will do the democratic think and go with the majority opinion and leave things as is. Thank you all for your various input it was a very interesting discussion. See you all later.

In 98 they went to dual fans for cars with AC. I don't know why a 98.5 has only one fan, unless there is no AC. Doubtful though. I have a 98 and mine use to set in the A-L range. In 98-99 they transitioned to the non-"NORMAL" guage.
