You see if I would have had one of those expensive mechanics doing my work for me I would have been asking him to do this right the first time! I mean it is right there in the wide open and it's like not hard to get to or anything? This is why I do my own work! I don't want to be at the track and find out some jack wheel who was working on my car calling himself a professional didn't even get my thermostat housing sealed correctly!
