Hello. I'm trying to keep my son's 2003 Z71 5.3 running until he can graduate college. I'm 62 years old and looking forward to retirement. Also looking forward to working on vehicles because I want to....not because I have to. I drive a 2014 Silverado 4X4 as my DD. My wife drives a 2014 Traverse. Looking forward to learning stuff here...and maybe contributing some.
