Mufflers repair service near Santa Venetia, CA

I brought in my 1987 Dodge B150 van. Yes, a really old van that wouldn't pass smog. A "gross polluter" per the smog shop. Michele and Dennis worked on my car diligently to figure out what the issue was. Turns out the timing was way off. After 2nd smog test, the van no.'s were really good to a low emissions vehicle. Yeah! Dennis also pointed out that my steering column was very loose. In the past, I've been told that the whole steering column needs to be replaced. But here at GF Automotive, it might be repaired, saving me a whole lot of money. GF is an honest auto mechanic shop. Hard to come by these days. Thank you Michele and Dennis for all your help!

I took in my 2007 Nissan Murano because the dealership said I had both exhaust manifolds cracked and leaking. Niki and his team discovered that I really only needed one replaced and the other would be fine for a few more years. This saved me a lot of money and I never would have known the difference! I appreciate the honesty. The other thing to mention was that they ran into some issues with the replacement because the old one was so beat up. Niki said it would take another day to complete, but I was going out of town with my family. He and one of his mechanics worked extra hard and got it done in time. Very good service! -Patrick Naylon

I love going to Clayton Valley Auto Service as Jeff and all those who work there are friendly, knowledgeable and do a very good job. When I had a check engine light Jeff's dad told me right off the top that it could be 4 or 5 different things and they would start out with the least expensive until they found out what the trouble was. I'm still driving that van around 5 years later. I really appreciate the great service they give. They are really great for routine maintenance, and wonderful when I have emergencies.

Great service
