      Does anyone have a wiring diagram for the ECT sensor on these? I found a disconnected connector by the alternator and cant find where it goes. Wires are yellow and black just like the ones going to the ECT sensor.

      ARE they Torque-To-Yield bolts?  The head bolts on my '92 and '93 3.4L DOHC engines are torque-angle but not TTY.  GM says they can be reused if not otherwise damaged--visibly necked-down, corroded, damaged threads, etc.

      Get a cooling system pressure tester from the "Loaner Tool" program at a parts store.  O'Reillys and AutoZone have them around here.  NAPA used-to.  Your location may be different. Pump up the cooling system, see if it's an actual leak or if you just have some leftover spillage. How many bleeder screws does the 3100 have? How hot is the engine getting according to a scan tool reading the coolant temp sensor?  Do the fan(s) come on?  What is the dash gauge showing?

      Little update, we got it tuned pretty good just having trouble making boost. Fixed a couple leaky intercooler pipes and it takes forever to build boost. Thinking maybe the 2 1/2 is too big for the turbo piping, probably will go to 2 inch. We have cam to put in which will help aswell. More vids coming soon
