Our Services & Offers


Air conditioning repair

We provide thorough air conditioning inspections to ensure an accurate diagnosis and comprehensive and honest assessments. All auto air conditioning repairs performed by us are done using quality parts and installed by a MACS certified auto repair technician.

Tires and wheel services

We offer competitively-priced  tires from the automotive industry’s best tire brands, including Goodyear, Michelin, Kelly, Cooper and Kumho.  We offer free lifetime tire rotation on every set of tires we sell. Our ASE-certified technicians are trained to accurately diagnose all automotive tire and wheel issues that may arise

Batteries, alternators, starters

Your alternator is an essential component that keeps your battery fully charged. As your engine runs, the alternator works like a generator to create electricity for your radio, windshield wipers, headlights and more.

Without an alternator or battery, your car couldn’t perform any of these tasks. Modern vehicles also use electricity to start your vehicle, so a dead battery means a dead car.



Exhaust System

The job of your car exhaust system is to manage the dangerous gas emissions created by your engine’s combustion process. It helps improve overall vehicle performance and fuel mileage, minimize noise and reduce the amount of pollutants released into the environment.

brake repair and service

Brakes should be examined at least once annually for the safety of your vehicle. Maintaining your vehicle’s brakes is one of the most crucial precautions you could take. You can have the confidence of knowing that when you press your foot to the brake, your car is going to stop.

Hybrid repair

The ASE certified mechanics at Cintech Automotive Repair service all of your hybrid repair and service needs. Hybrid vehicles need special care and our staff is prepared to provide the unique care that your hybrid vehicle requires.

check engine light diagnostics

Thanks to the check engine light, we can easily know when something is amiss with our car. The benefits of getting your car issues diagnosed are endless. With a check engine diagnostic test, you may be able to catch a small problem before it becomes a bigger and more costly issue.

Missouri State Vehicle Inspections

Safety inspections are required of all vehicles; however, only residents in St. Louis, St. Charles, Franklin, and Jefferson counties are required to take the emissions test. Vehicles with even model years will be inspected on even calendar years; vehicles with odd model years will be inspected in odd calendar years.

  • 5 star review  22 years ago, a dear family friend referred me to Cintech Automotive. I am so truly glad and blessed that they did! Cintech Automotive is a Christian family-owned shop with outstanding auto repair service, reasonable prices, and honesty! Honesty because if they feel that something does not need to be repaired, they will tell you. If there is a case where you may be needing brakes or some sort of fluid service, they will let you know when it is time. They will not tell you that you need it right now if you don't need it. We have all been there when it comes to bringing our vehicle to other service centers, and they will tell you you need something done when you really don't! Cintech Automotive will not do this. Ongoing honest, quality service is what you are going to get with Cintech! Thank you to Greg, Cindy, Casey and all the guys for their continued service on our vehicles and keeping them on the road these past 22 years! I look forward to the next 22 years and then some with Cintech Automotive!

  • 5 star review  Been taking my car there for years. Wouldn't go anywhere else. They don't just treat you like a customer. They treat you like family! Very honest and professional. Always willing to work with you in anyway they can.

  • positive review  I will never take my car anywhere else when I’m in Missouri. Friendly, honest, knowledgeable staff. Recently bought a new to me car but didn’t have them check it out first (shame on me). Turned out to have a multitude of problems. I had bought a warranty and Casey got the warranty company to pay for something they told me they wouldn’t cover over the phone. They fixed all the issues faster than originally said. And the work is always top notch. I lived in Florida for 10 years and compared all other automotive shops to them!

  • 5 star review  This family owned operation is top of the line. From the very 1st time I walked in Cintech, I felt like their number one customer. Casey, Tim and the rest of the team have listened intently to all of my descriptions of sounds, noises and clunks and have been able to accurately and conclusively diagnosis the issues of my 1999 Ford Ranger. Always affordable and reasonable, Casey even has a bonus club for regular customers. I recommend Cintech Automotive Repair to ALL.

  • 5 star review  When my car decided to die at the worst possible financial time Cintech came through and delivered wonderful service with exceptional pricing. As a young woman out on my own in an unfamiliar city I was stressed to the max! I From the business manager to the mechanic every interaction I had was friendly, efficient and informative. Being new to the area I was very nervous to go to an unfamiliar shop but it couldn't have worked out better. Thanks again Cintech!
