“Russ is very knowledgeable. He analyzed my smoking-hot 7.3 to provide some diagnostic advise for my oil leak. Looking forward to working with your team again.”

“Russ and his crew are freaking awesome. Truck delivered back on time and the absolute BEST price around. This is the ONLY shop I can trust.”

Wes W.
Aubrey, TX

“I am usually a ‘take-it-to-dealer’ type of guy, but after getting screwed around several times by two different Ford dealers, I was looking for options. I remembered seeing a mailer from PowerFlo, so when I had a problem with my F350, I called, and am really glad I did. They helped me with a tow truck company, diagnosed my truck and called me and walked me through the whole repair from start to finish. They also recommended things to help avoid future issues. I got my truck back and it was the best money I have ever spent on it. If you have a diesel truck, take it to PowerFlo!!”

Doug W.
McKinney, TX

“OMG, FINALLY!!! After the McKinney Dodge dealership attempted to repair my A/C three times, conveniently riding out my warranty period, PowerFlo not only ‘fixed’ the problem instead of patching it, but my A/C blows colder now than when we drove it off the lot 10 years ago. (The A/C was blowing out warmer air on the passenger side — Dodge design flaw.)

“After an injector went out in the Dodge, I was determined not to step foot back at the dealership. I was referred to PowerFlo and read organic online reviews. It's true, y'all! If you need any repairs done to your diesel vehicle, take it to PowerFlo and save yourself some time and stress worrying if you can trust your mechanic! Their communication is transparent, customer service is bar-none and their work is top-notch! Regardless of the ONE negative review that says they don't honor their warranty ... I know firsthand that they DO! They will bend over backwards actually. You're welcome!!”

“Russ Chalko and team at PowerFlo Diesel are conscientious, thorough and efficient. When I am in the McKinney area, I use them for regular maintenance items (oil change) and anything else that comes up. They keep me informed about potential problems and recommended maintenance and repairs. I think that PowerFlo is a good place to take your diesel truck for service.”

Tom C.
Dallas, TX

“Russ and his team keep my fleet of Ford F250s running, and at their age, that's not easy. He has worked on all three of them, including two old 7.3s and a newer 6.0. All are well over 200K miles. They are honest and thorough. I would not take my diesels anywhere else.”

Dave J.
Allen, TX

“After lots of frustrating experiences with the diesel mechanics at the local Ford dealerships, Russ over at PowerFlo Diesel is an awesome alternative. They did the work needed in the 24 hours as promised and got my truck back to me quickly. I pull a gooseneck trash trailer for a living and so having my truck sit at the dealership for 2 to 3 days just to pull the check engine code is not an option. PowerFlo Diesel stepped in and made the truck repair process speedy.”

“Russ and his guys are the only ones I use for my truck. They know everything about my truck. I have recommended this place to all my friends.”

Deep Ellum, Dallas, TX

“As much as I count on PowerFlo to keep my Duramax running. I hate to spill the beans on a great shop. I put 3 to 5 thousand miles on my truck weekly and can’t afford problems. I brought it here with issues and they fixed it where GM could not. Their answer was just ‘buy new’! Frustrated with your truck? Try them.”

David K.
Celina, TX

“Russ is a great tech and really watches the details. He has worked on my trucks for years and always handles any problems that pop up in a very professional manner. The PowerFlo shop is one of the cleanest I've ever been in .... It makes it a ton easier to drop off and trust your truck to a shop when there's not old parts stacked everywhere. Great team ... highly recommended.”

Shane M.
Frisco, TX

“Took my husband's truck, several times, to different places. We were recommended to this place. Thankful for the great work. We have now found our local mechanic.”

Dana K.
Winchester, TX

“Really great shop, not just for diesels, but any vehicle. I brought my car in for ‘noises’ and Russ took care of my car, and was really nice and professional. He explained what was wrong and how he was going to fix it. I HIGHLY recommend this shop for all your vehicle maintenance.”

Tonya C.
Keller, TX

“Russ has worked on all my vehicles (diesel and gas) for years. His work has always been top-notch, and when I contacted him recently for an invoice with my mileage when my truck was stolen for the insurance company, he offered to find a truck for me at auction. Not only did he put up with me constantly asking questions, but he found the perfect truck for me. He has always gone above and beyond and I cannot recommend him enough for any of your automotive needs.”
