  I waited a year to see if there would be problems with a timing belt kit install on a Sequoia.  There are none and the Truck runs great, that s why I gave 5 Stars. I would go back.

  Excellent service.

They’re very professional and would always recommend them, the diagnosis was accurate and fast.
It was a  transmission failure  therefore I needed a replacement, which they delivered at a timely manner, despite the amount of work involved.

Great work and quality.

  Yesterday morning as I prepared to leave my home, my car sputtered to start. I drove to Dale's and thankfully my car could get booked in to check the source of the problem. Within 15 minutes, I was called to advise me that I needed a new battery. Within two hours my car was ready for pickup. I have been a customer for many years and I have always received friendly, informed and timely service.

  I had such a positive experience with Dil and the entire team at Dale’s Auto Service. From the moment I walked in, everyone was incredibly friendly, welcoming, and professional. They took the time to listen to my concerns, answer all of my questions, and explain everything in a way that was easy to understand without ever making me feel rushed or uncomfortable.

As a woman, going into a mechanical or automotive repair facility can sometimes feel intimidating, especially if you don’t have a lot of mechanical knowledge. Unfortunately, it can be difficult to know whether you are being given all of the information or being treated fairly. My experience at Dale’s Auto Service was completely different. I genuinely felt respected, comfortable, and included throughout the entire process.

Dil was especially helpful and made the whole experience incredibly easy. He was patient with all of my questions and made sure I understood what was happening with my vehicle, what was recommended, and why. There was never any pressure, confusing terminology, or feeling like I was being talked down to. Everything was explained professionally and clearly, which gave me a lot of confidence in the work being done.

Dale’s Auto Service really does feel like a women-friendly automotive facility. The staff creates an environment where you can comfortably ask questions and actually receive thoughtful, honest answers. They make something that can normally be stressful feel straightforward and manageable.

I also really appreciated how organized and professional the entire shop was. The communication was excellent, the customer service was friendly, and I felt like my vehicle was being taken care of by people who genuinely care about doing the job properly.

Why is Walnut Shell Blasting Necessary for DIT Engines?

In direct injection engines, fuel is sprayed directly into the combustion chamber rather than over the intake valves.

As a result, the intake valves are not regularly cleaned by fuel, leading to the accumulation of carbon deposits over time.

This carbon buildup can restrict airflow, disrupt fuel-air mixture, and negatively impact engine performance.

Walnut shell blasting is necessary for DIT engines to

1. Restore Engine Performance: By removing carbon deposits from the intake valves, walnut shell blasting restores airflow and ensures proper fuel-air mixture.
2. Prevent Engine Damage: Excessive carbon buildup can cause valves to stick or become damaged, leading to costly repairs.
3. Address Common Issues: Carbon buildup on intake valves can cause rough idle, hesitation, loss of power, and increased emissions.

Walnut shell blasting effectively addresses these issues, restoring your vehicle’s drivability and reducing harmful emissions.
