Over the weekend, I got my car back with the brand new AA v3 si kit beautifully installed. On the dyno, the car made about 550rwhp. The car really feels different now and I love it.
But, there seems to be a problem (in fact, not really sure). The cooling fan starts to run at full speed after 3 mins. from cold star in the morning. I was told of the problem by the valet, the first day I brought it back to my home, that I had brought back a 747. The coolant temp. is at 220 and I live in LA. The weather has been in mid 80s during the day. I don't beat on the car and I live about 5 min drive from the campus.
im not really sure if this is normal. If this is a problem, plz advise me as I would love to get it fixed.
The big silver tube coming out of the top center of the engine, "charge tube" will have a an electric connector on it. This connector connects to the MAF and barometer and iat sensor inside that tube.
Some supercharger kits have this connector farther away than stock and require an extension, and some other folks will use a barometer/iat break out extension to remove the barometer or IAT sensor and put them elsewhere.
Some folks have reported strange fan behavior when this connector is unplugged or one or two of the pins inside the connector are bent or have slipped out. It's an easy enough thing to check, unplug it and eyeball it to make sure all the pins are the same length and not damaged or missing.

Here, but not really visible in this pic:
on this now after reading on it I never ran across this problem in the c5 set up. But if your car is truly hitting those temp that fast and is staying at those and higher something is wrong.
I was told by the tuner, earlier this morning, that he had indeed set the temperature to go on after reaching a certain temp. (After 185 to be exact).
but, the car reaches that temperature literally 2-3 mins after cold star in the morning. I think that is too quick.
Im just worried about when summer kicks in or I get on a long road trip with this car in a canyon.

Like the other guy is saying here did you buy a brake out sensor for the set up. Look at what he is telling you to look at here but I really don't know much about that part on what he is saying that has happen with others. But did see from one other guy in here the same thing did happen also so that lets hope that is all it is. Robert
Not supercharged yet, but when I did headers and intake I added a 170 degree thermostat. My car always ran 202-210 degrees. Now runs in the mid 180's. The stupid engine temp guage always reads 220 and is incorrect. If you select "Touring" mode it will give you the correct temperate...

Crazy GM can do relly good on stuff in the past then on every one I have seen reads like that. Good point here.. Robert
My guess it's a maf pin slip issue. Take a silver maker run it across your maf wires unplug the sensor and see if all pins are the same length. Chances are 1 & 3 are shorter . Pull gently on pins with needle nose pliers to even out and see if you can reconnect without them moving. You will see it with mark you made with the silver marker. I fought this problem when I did my install and finally removed the harness casing when I did a baro/ iat breakout . Tapped it all up and no more issues.
I just got back from a road trip in my A&A car. My average temp is 205 and the fan runs constantly. Good timing on this post as I was going to look into this. I'm curious what will happen when summer temps hit 110 as well.

hi chief, mine is always at 220. I drive about 3miles a day.

thank you sir. I will bring your and other suggestions provided above to the tuner on sat. Just too much info for me.
Who did your install? Did they forget to put parts back on? If they're that disorganized they somehow forget a rather large piece, I'd be worried about missing fasteners all over the place. Plus, that engine cover is filthy, how'd that happen?
Why is the fresh air vent missing from the rear of the radiator?
I would think it helps cool the under hood temps.
uh... I am pretty sure that's mostly for lift reduction. It is sealed to the radiator so it doesn't interact with heat under the hood at all. If anything, it keeps about 1/3 of the cool air passing through the radiator from making it to the engine.
Edit: nevermind, I don't know what my brain was on about.

A&A SC installed, but a problem."

I was about to lose my mind reading all that other BS.
