Replaced my lim gasket over the weekend. Wasn't to hard at all. Flushed coolent while I was working on it too. Autzone must have gave me the wrong thermostat because the one they gave me was totally different.
Not sure but seems like replacing the lim gasket gave me better gas millage. You. Think that is possible? I did clean the engine parts and found a lot of carbon gunk built up sitting in crevices of the lower intake.
It was a learning experience for me. Thanks to everyone here who has helped me prepare and with your knowledge.
