I love this site! Just want to pass on what I learned the hard way about auto repairs. I think there are so many unscrupulous shops out there that this one of the most difficult repairs that everyday people are faced with. If there is no warranty---watch out! Know your service shop---check them out. Get second and even third estimates and evaluations, if you can. The problem is that we all need our cars and usually are in a rush to get it running again! Two years ago I took my car into a shop that gave me a fraudulent warranty.
