Not to contradict anyone here, everyone here is very knowledgeable. I did the mod. I have the SLP UDP. I've had it on my car for about a year and a half. I have had no problems with it. No cooling problems at all. I was DDing my car during a few weeks of 90-105 degree days in stop and go traffic and I had no cooling or electrical/charging issues. No problems whatsoever.
But I will advise you of this...when you, or if you, do the swap, make sure you go to a GM parts store (at a dealership) and get a brand new crank pulley bolt. The old one will be no good once it comes out. Don't even try to use it.
And also, make sure you, or whoever does the install, follow the torquing procedure to the letter. Do not skimp out, do not take a short cut, do not skip it at all. If you take the car to a shop to have a mechanic do it, then before you go, download and print out the torque procedure. Bring it with you, give it to the mechanic, and watch him do it exactly as it states and shows. I hate to sound all dramatic, but it is important that the torque procedure is followed. I can all but assure you that everyone that had problems was due to improper seating and torquing of that bolt. Outside of that, I am sure you'll have no problems.
