I did the PI install today and everything went smoothly for the most part...I will go into detail in another thread when I have more time but here are the issues I am working with

Car runs fine and seems to run normal.

Check engine popped on after maybe 10 miles.....(getting that checked tommorow)

I have an aftermarket autometer water temp gauge that I had plugged into the drain plug in the block...I removed that sending unit and used put the second stock sending unit there (99+ only have 1).....My friends and I were thinking maybe we could splice my autometer sending unit wire into the stock gauge sending unit...problem was there was two wires for stock and one for my aftermarket....so we tried both...one wire didn't work and the other seems to make my fan stay on..(I think). that brings me to the other problem.

My fan is on all the time......I know someone else had this problem but don't remember who and what the fix was....Is this bad for the fan to be on all the time....I don't plan on driving it anymore than I need to...but I don't have a lot of time to work on my car right now....have finals all this week as well as work.

let me know what you guys think......and does anyone know of a way to splice my autometer gauge into the factory sending unit? would rather do that then have to tap my thermo housing.

oh I also changed my thermostat to a 180...I don't think that would affect anything

post code on check engine light , autometer guage isnt going to work off factory sending unit , you need to tap the intake for the other sensor and mount it up top or mount the sending unit for the gauge there either way should work , thermostat shouldnt hurt anything . If you wire the factory sending unit back like it was it should fix the fan problem i would assume .

do you think it's bad if I leave it the way it is right now with the fan running at all times?? I mean I know it's not hurting the car at all...but how bout the fan? I just don't have time to get under the car....probably have to wait till next weekend.

I will post the code as soon as I get it

In the summer time I don't think it's bad to leave the fan running all the time but I still plain on fixing the problem. I did the full motor swap vs a pi head swap and have the same problem as you. No shop in my area will even think about drilling and tapping the intake and so I tried a T fitting but all that did was cause overheat problems because the sensors were not reading the temp till it was too late. I am now waiting on a little extra money so I can buy the flex-a-lite fan PN 210 according to flex-a-lite it will fit across our radiator (cost 280). It has it's own temp sensor built in so when the radiator heats up it turns on plus its a twin fan set-up and I can still put it on a switch for when I'm at the track. And putting just one sensor on won't cut it I tried to see which one would allow the fan to turn one and off and it would never come on
