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.

  • We started taking our vehicles to Cintech when we owned a delivery company. They did a great job of keeping our vans on the road with quick efficient service. We've used them on all our personal vehicles for 15 years or more. They were even kind enough to "go through" a car that we were buying for our new 16 year old driver. They are the best

  • Always honest and up front about the work that needs to be done and what the cost will be. Now if we could just figure out how they could also do our dealer warranty service so that we didn't have to deal with the dealer any longer, it would be perfect. 🙂

  • Took my trusty old Honda Odyssey to Cintech based on feedback received at work and on the web. I had a list of "to-do" from the Honda technicians when I visited them. Cintech folks took the time to inspect the van and recommended only the changes that needed to be done. I liked the fact there was no hard sell unlike some other places I have taken my van to. The van was fixed as per Cintech's recommendations and to our satisfaction. The staff was friendly and took time to explain what fixes they were recommending. I have to agree with the others that they did an excellent job of taking care of my van and ensuring that it was on the road as quick as possible. Thank you !
