just wanted to post a great thanks to all on this site, was having probs. with heat not working well. did search and found that heater core was more than likley blocked and that is needed to be flushed. there was more than enough post on how to do this and great pics to show which lines to flush. did this yesturday and now have great heat, have a feeling will be spending alot of time here.

 

Good deal that you found what you're looking for. This is a great forum.

On the forum note, I noticed that you have a 93 Z28. If you go to www.speeddensity.org we have a 93 specific board set up with several VERY knowledgable people over there. It may come in handy.
