I purchased this 2000 Cougar v6 for my son's senior year in High School, and here I sit 3 weeks into his first year of college and he has succeeded in overheating the 2.5 and ruining the engine. We heard some talk about a 3.0 conversion, and since I have been in th automotive industry for over 17 years I thought it might be something I could do. He has since purchased a 2000 3.0 S code engine with low miles and I am getting ready to tear it down, but thought I would get some input on the engine choice, whether it will be OK with and automatic, and what direction I should go in first. I don't really want to go into it if this is the wrong engine choice. Please give me some direction.
