Hi, I have been working on my Caddy 2001 sts for a while now. The problem was that every time I added coolant it quickly drained out from somewhere. I finally figured out the problem. I had to replace the gasket and the thermostat, as well as the lower hose on the thermostat assembly. So, I did all that put it back together and added some coolant. Then I realized it was still dripping out. That's when I noticed that the coolant was now draining out from where the freeze plug goes. It wasn't there anymore. Obviously I wasn't happy. Now I need your help. Do you know where I can find a step by step guide to fix this? Also, are there any other things that I should know about when preforming this? Thank you very much for your time.
