In Fresno, shops are busiest on Monday mornings and before holiday weekends, so a mid-week appointment gets a car seen faster. Labor rates across California vary by neighborhood and by shop type, from small independents to dealership service bays, and mobile mechanics now cover many routine jobs in the driveway. Before authorizing a repair, ask for the estimate in writing, whether the shop warranties parts and labor (12 months / 12,000 miles is common, some offer more), and whether it can provide a loaner or a shuttle. Check the listing for hours, the makes the shop works on and its Google rating, then call ahead, since walk-in capacity is limited at smaller shops.

The business lists hours on 5 days of the week. On most of those days it is open 8 am–4:30 pm. It is closed on Saturday, Sunday. As with most places, expect changes around holidays; the phone number below is the fastest way to confirm. The listed phone number is (559) 264-2891. Many businesses also reply to text messages on the same number if it is a cell phone. Its website is cleandieselspecialists.com, where you may find menus, price lists or booking options.

On Google it holds a rating of 4.9 out of 5 from 130 reviews, which is a strong result for a diesel repair shop in Fresno and suggests consistent service.

I had an issue with my Freightliner truck not going into gear and was worried it might be a major transmission problem. I brought it to Diesel Diagnostic Tec, and I couldn’t be more impressed. The team quickly diagnosed the real issue—it wasn’t the transmission, but a problem with the clutch. Their expertise saved me time, money, and unnecessary stress. From start to finish, the experience was outstanding. The staff was friendly, professional, honest, and extremely knowledgeable. They were upfront about what needed to be done and walked me through the entire repair process. The repairs were done quickly and professionally, and the results speak for themselves—my truck is running like new again. The front desk service was just as impressive, and the waiting room was clean, comfortable, and welcoming, which made a big difference while I waited. This is, without a doubt, the best diesel mechanic service I’ve ever experienced. From now on, Diesel Diagnostic Tec is the only place I’ll trust with my truck maintenance. Thank you for your quality work and true professionalism. You’ve earned a customer for life!

After taking my truck to 3 different diesel mechanic shops and they couldn’t find the issue with DPF system, I brought my truck to Diesel Diagnostic Tec, and I couldn’t be happier with the service. The customer service was absolutely top-notch—friendly, professional, and genuinely helpful from start to finish. They diagnosed and fixed the problem quickly without cutting corners. Their pricing reflects the quality and expertise they bring to the table—totally fair and well-deserved. If you’re looking for a reliable, efficient, and honest diesel shop, I highly recommend Diesel Diagnostic Tech. I’ll definitely be coming back for any future work!
