Diagnostic services service near Fullerton, CA

Very helpful, knowledgeable and accommodating. They should change their name because they do much more than just tuneups and lube jobs. And, as a bonus, they are quick and friendly. One of the employees even offered to give me a ride there and back when my car had to be kept for a few days.

These guys are the BEST!!!! They have helped me so many times! Quickly and fair, and prices always what I can afford. I LOVE THEM! Dana Chisholm

This was the only place that can get my tire on the fly. I have a tire size that's hard to find quickly and The pricing was perfect. The service was great!! And pretty quick. I came in today and will be back in a few weeks for more work. I had a screw that was in a very bad area of my tire preventing it to be repaired. Before they charged me for the tire they took a look to see if it was repairable. Thanks guys!! Darcie Ragans

These guys are awesome Francisco has the best customer service he's staying after closing to solve a problem with my dad's ac. The cost isn't worth staying after but he goes above and beyond. This is my new place to bring my truck and refer my friends and family to, not only is it low priced service they are also honest. Good luck FNP wish you guys the best keep that 5 star rating you guys are number 1!

First clue, ripped off, the bad about a 22 year old after a 31 year seasoned businessperson. Ray

My wife’s expedition blew a heater hose while at Coffee Bean with steam coming out from under the hood she drove next door to American Tire. The guys “T” as in Mr. T was very helpful, even assisting her a tow to the dealer through AAA (garages don’t typically assist you going elsewhere, but they were helpful). Upon arriving to assess the problem I realized the “new” heater hoses are not hoses at all but rather multisegment manifolds. I felt comfortable with everything explained, they confirmed that the parts were available and it would be done by the end of day and it was. Very happy with the service and how we were treated. 5 star all the way!
