I'm ordered new copper spark plugs and the 180 Tstat. anything else I should do or check or replace since everything is already apart? I was thinking maybe new fuel injectors?
Call a few GM dealer parts departments with the part number given in Techinfo 38. That number may be superceded - if so get the newest ones. Some dealers charge $59; others want $80. Be prepared to hear the gaskets won't work in your car, or are not spec'd for your car. Ignore that - they will.
Get a package of Dorman "Help" line plastic coolant elbows.
If you are running Dex, flush it out and re-fill with "mixes with any" according to the method given in Techinfo 100
Flush the oiling system as described earlier.
