| I like it right where the 100/150 puts it. Leaves plenty of room for movement prior to red zone/high temps.
In 15 miles of sand running at 90+degrees ambient Saturday (and with a total load of about 800 lbs), the gauge never went past horizontal. In fact, when I ran in low-range, the gauge never got within a needle's width of horizontal (probably never above 195). When in high range and experimenting, I did get to horizontal once or twice in some really soft, deep sand. Maybe 200 degrees? A/C was on, too.
Looks like my cooling system is working well.

Thanks B. I wasn't really concerned about it and thought it was somewhat to be expected. If I was one of those that's got a vehicle that's running hot (AC cutoff hot that is), I'd be worried about it. That extra spike at shutdown can't be good if you're already at 225 to 230. 
Rookie2 |
the spike is in water temperature only, CHT (Cylinder Head Temperature) gets no hotter after shutdown
I am still experiencing pop ups in temperature with low speeds, I do want to do the fan clutch mod, Going to adjust it and top off the oil, but I only have one day off a week right now and very little money not a good combo for working on the 80,

Looks like my cooling system is working well. | Mine climbs often just driving around. I got to within 4 or 5 needle widths climbing a fairly steep hill near home.

| extremetoy, noone has done this for a 91. The 93-94 and 95-97 turned out vritually identical despite different part #s so if you pull the gauge and photograph it we can likely tell you if the same mod will likely work. right now raventai does not have time for any more bench testing so that is likely as good as we can offer.

(I'm having issues with posting functioning links) | I found some resistors locally that are 2 watts and 2%. Do those of you who would know think that these would work? Was the 3watt and 1% rating speced off the OEM resistors?
Thanks, David Sword |

| IIRC the OEM 75 ohm resistor was 2w, it got very hot (fingetip burn hot) when reading higher temperatures where the current through that resistor was high, with the move to 3w resistors they are better able to handle the current and run cooler witch helps them retain accuracy,
the mod resistors are of a higher resistance this somewhat lowers the current,
so the 2w would probably work but are borderline and will get hot maybe not quite as hot as OEM resistors, IMO the 3watt wire wound resistors are preferable
% of the OEM resistor is unknown, the lower the better but accuracy %, but really no diffrence between %2 and %1

| raventai, while i've got your attention on this thread, a quick question about my 93 gauge. Is there any chance it could electrically have a dead spot just below the bottom of the red line? I towed a 4500lb boat over a bunch of mountain passes a couple of weeks back and it never exceeded the top of the needle just about touching the bottom of the red, although it regularly went to near that point and stayed there for a long period on long climbs without climbing higher. i am pretty sure that's just where my modified fan clutch kicks in to do its job but I'm just curious if there might be another reason.

| nope no flat spot, I have a full set of temp pics for that particular gauge if you want them.
I would agree that it is probably something that kicks in at that temperature, fan clutch sounds like a good suspect,

| Ok let’s try this
click here FTP
You should get log in box of some kind,
user name = ih8
password = mud
browse to /Pictures/93-94/110050, copy all the .jpg's to your computer, you should be able to just select copy and then paste and they will start downloading,
That is the "after mod" pics for your particular gauge, you can copy the stuff from all the other folders also, it is the full documentation of the project,
If anybody else want them grab them be my guest but do not expect great speed, I will leave it up and running for the rest of the weekend or until my IP cheanges witchever comes first,
If it is not working for anybody let me know and I will try to fix

| thanks rt but i get a username or password error when i try it in lowercase or caps.
is there not a program that will do a mass resizing in windows, so they could all be reduced to 150kb or something? if i can grab yours I will resize them using my mac and post them up.

| I've got a PM it no one else can connect either, I may not be able seve an FTP,
i have photoshop but dont know how to mass resize, I am sure photoshop can I'll have to look into how.

| Semlin I uploaded the set to Kodac galeries, Kinda stupid way to do it but I think it will work
Pm me a disposable spamable E-mail address and I'll send you the silly invite Kodak makes you use,

I replaced my radiator (and other cooling bits) in late August (or was it September?) and with the the 100/150 mod my gauge has never gone above horizontal which according to the ODBII scanner is about 200 degrees. Once warmed up the gauge regularly goes from about 2 needle widths below horizontal (185ish) to almost horizontal (195ish) during normal driving (on/off freeway, around town, etc.) All in all I'm very pleased with where these resistors put the gauge with a (now) health system.
Tarbe, are you observing behavior similar to mine now?
I can tell you that before I did my cooling system overhaul the AC would cut off when the gauge was about 1.5 needle widths from the bottom of the red line which according to the ODBII scanner was 222 to 224.

Come to think of it I'm not sure where my notes are now... probably in storage with just about everything else I own.
