LS2 technical hel needed...
Alright I know this is the corvette C6 section, I have a C5 Zo6 and a Trailblazer SS with the LS2. No one on the TBSS site has been able to help yet so I was looking to pick someone's brain on here. On my Trailblazer SS I decided to wash and re oil my K&n drop in filter, do the whole process (Been using them for a long time, I don't think I over oil'd) and when I start her backup, my check gages light comes on, and then check engine. I re checked all connections, cleaned the MAF and started her back up again. This time only light on is check gages, I let it run for about 2 mins and the oil temp gauge never came up at all, stayed unmoved. Used Onstar to run diagnostic and they said they were getting a coolant system error, 3 of them. Any specific connections or things I should check before bringing it in for service??? ANY help would be awesome!

Check all your connections. Sounds like you knocked a sensor wire loose.
How did you clean the MAF sensor? Should use electrical contact cleaner or alcohol.

I agree w/the knocking a wire loose theory and make sure you do put back the stock filters before going in,GM did a bulletin a year or two ago regarding oil from these things and no warranty because of it,so watch yourself.

Guys thanks for the advice, I went and bought a fram paper filter so I can bring it in tommorow. I am going to pull the battery cable now and check some fuses, connections, if I can't find anything its going in tommorow. Thanks to everyone for the help, you were more helpful than the TBSS forum.

Well I pulled the proper fuses, disconnected the battery, and checked all connections... Nothing was loose, the light is now obviously out because of the disconnecting/reconnecting of the battery, I drove it hard for about 10 mins and everything is clear, no lights on. I am going to bring it in this week and have it looked at to see if anything is still wrong, but it seems like I got it. Again thank you guys, this forum is awesome when you need help!
