Thank you very much for saving my daughter and her family a lot of money on her Honda. You are definitely on my list for future help. Thanks, again. I just heard from my mechanic. You were right Your response was received in less than 10 minutes!!

Your answers were clear and the diagrams were perfect. I really appreciate his help. I was ready to trade my new Honda until he told me to wait until I got 3, miles on it and my gas mileage would get much better. I took the Power Steering O-Ring service bulletin linked from JustAnswer to my Acura dealer, and not only did they no-charge the o-ring, they also replaced the power steering pump at no cost.

Wonderful service, prompt, efficient, and accurate.
