Schedule Mercedes Timing Belt Replacement in Atlanta, Georgia
A timing belt is a toothed belt that keeps the top half of your engine aligned with the crankshaft and pistons in the bottom of the engine. Timing belt replacement is important because allowing it to go unrepaired can lead to very expensive engine damage. Your timing belt choreographs the timing of your combustion process as your pistons travel up and down in the cylinder. Intake valves open at a specific time to let in air and fuel and they close at a specific time to allow the fuel to burn, and then the exhaust valves open at the right time to let out the exhaust.
This may sound like a complicated process, but the timing belt is designed to make it all happen seamlessly. A typical timing belt replacement timeline is every 5 years or 60,000 miles, whichever comes first. A faulty timing belt can have a directly negative impact on your engine. If your timing belt breaks while driving, your engine will stop working completely. The best way to avoid this is through preventative scheduled maintenance.
McCullough NAPA Auto Care staffs ASE Certified technicians with the experience and technology to properly diagnose any timing belt issues you may be experiencing with your Mercedes. We’ve been in business since 1969 and have ample experience repairing and replacing timing belt systems for any Mercedes model, including all their sedan, SUV, Wagon, Coupe models, and more.

January 7, 2021I live in Brookhaven and work in Duluth and pass dozens of auto repair shops on the route. I will forever go out of my way to go to McCullough. This is hands down the best repair shop I’ve ever been to. They are honest, kind, and treat each customer with the utmost respect. I’ll never take my cars anywhere else!

We have been depending on McCullough's at least since 1997, when we purchased a home only a few blocks away, walking distance really. Had our emissions test a few days ago and want to acknowledge Jack, who completed the tests quickly. I asked him to determine why the backup camera was not in the proper position. It took a bit of time and ingenuity to get everything right. Thanks Jack, for the excellent service.

This place is a life saver. Great communication, great service, and very professional people. Eric worked with me through my whole repair. Kept me updated through out the process and fixed the problem on my car at a fair price. I will definitely make this my new place to go for all my car repairs and maintenance needs, along with sending my friends their way.

March 10, 2020Wow! I am so impressed with the service I received. Having moved here from Nashville I was nervous about finding a mechanic! These guys are BUSY but they treat every customer like their priority. I got my car repaired within two days on a weekend! Prices can’t be beat and I was getting phone calls with detailed status updates. Amazing service. Really compassionate. Please doing business! I thought I was going to have to spend thousands fixing the plate that was dragging under my car but I got it fixed for under $200! Thank you!!!

June 7, 2021Eric was amazing from start to finish. I chose this shop for my repair based on previous reviews & I'm glad I did. He made sure to, in my opinion, go above and beyond with his politeness, as well as helping to make the process smooth and to try to save me as many coins as he could, while still getting done what was needed. Very happy with this visit

November 4, 2020Great customer service! Eric and team did an awesome job coordinating their busy schedule with the schedule of my girlfriend and myself so that we would have a car during the work week and then trade off cars when the other was ready. They are extremely friendly and it felt like they had us as the customer in mind. Highly recommend!

McCullough has been my family's go-to mechanic for decades. Don't know what I would do without them - just a super-nice family that will take care of your cars. Their service is important to us because once we get a new car, we like to hold onto it for years (10-12). Highly recommend.

August 2, 2021My experience was surprisingly excellent. I was greeted immediately before I could actually get out my car. Eric was professional and friendly. Eric Followed up with me has promised. I really like that Eric shares real honest timing/wait expectations.

July 20, 2020I would normally recommend this business as I have been here a few times. I went there Friday for an oil change. However, I honestly didn't feel safe. They have signs that customers must wear a mask. There was only one employee wearing a mask themselves. All the others didn't have a mask on. I feel this is disrespectful to their customers. I understand it can be uncomfortable but it is essential during these times.

October 21, 2021I have used McCullough for maintenance on my prior vehicle and received great service. Recently I had to repair my front bumper - I received an estimate for repair services that was reasonable. The estimated turn around time was less days than other auto shops. The best part was, the staff (Graham) was accommodating with my schedule and the repair was completed as expected/on time. The work completed was great. I absolutely recommended McCullough for auto care services.
Jessica Astrid George
February 23, 2021Quick and excellent service. I was turned away at my regular mechanic because he said he didn’t know how to do a transmission fluid change. This was my first time ever going to McCullough auto care, and I was very happy with my service. They were able to see me immediately and were patient with me considering the circumstances. Eric was great, and even matched the prices of another mechanic down the road. I will be back! Would recommend!

I own and automotive repair business in Jacksonville, but my wife lives in Atlanta and needed tires for her car, so I know good service and fair pricing in this industry. I chose McCullough because of their good reviews and they did not disappoint. They were very professional and took good care of my wife. I would highly recommend them and will continue to use them for her service needs.
John Greenfield
October 21, 2019I was so impressed with these guys!! Family business and the guys are professional, efficient, and personable. They got my part quickly and fit me in so I could come while my kids were at school. They went the extra mile (no pun intended) to consult with another auto body shop to make sure the repair was stable. I will be coming back for all future auto needs and will recommend them widely.
Deb in Atanta
September 10, 2019Always extremely professional. Willing to work with customers. Sadly, car repair is expensive but they have worked with me. Graham has been extremely helpful with issues my daughter was having with her car while we were at another mechanic in the area. We asked on Nextdoor for recommendations and McCullough came up numerous times!

January 23, 2020Very honest mechanics. Eric kept me in the loop with my cars progress. I got the car back in a reasonable amount of time considering the work that had to be done.
Michael Brown
January 30, 2020Brian and the team were fantastic with handling my issue. In fact they discovered a major error which occurred when I had my last oil change done at a quick oil change place, which turned out to be the cause of my issue. They took pics of it and wrote out an explanation for me to give to the previous oil chance place. Because of their extra effort, I am getting reimbursed for the error. I highly recommend Brian and the team!

Signs You Need Timing Belt or Timing Chain Replacement
A bad timing belt may produce a ticking, rattling sound from the engine as the belt develops a looser fit against the engine. Misfiring or backfiring is also common with bad timing belts. Here are 5 signs that your Mercedes timing belt or timing chain needs replacement.
Engine Misfire: One of the primary signs of a timing belt or chain issue is engine misfires. The timing belt or chain synchronizes the rotation of the crankshaft and the camshaft so that the engine’s valves open and close at the correct times. If the belt or chain is worn or damaged, it can slip and cause the engine to misfire. If left unresolved, this can lead to a catastrophic engine failure.
Ticking Noise from the Engine: A ticking noise from the engine is often indicative of a worn or loose timing belt or chain. The belt or chain connects the crankshaft to the camshaft, controlling the opening and closing of the engine valves. If it’s loose, it can produce a ticking or clicking sound as the engine runs. This should not be ignored as it may lead to serious engine damage.
Rough Idling or Difficulty in Starting the Car: When the teeth on the timing belt wear out, they can detach and fall into the timing chain cover, causing the engine to idle roughly or making it difficult to start the car. The engine may also stutter or stall due to the inability of the valves and pistons to synchronize properly.
Oil Leakage: A worn-out timing belt or chain can lead to oil leakage from the front of the motor. The belt or chain runs through various engine components, and wear and tear can cause these components, like the timing cover, to loosen. This looseness can result in oil leakage, which can lead to more severe engine issues if not promptly addressed.
Engine Fails to Turn Over: If your Mercedes’ engine will not turn over or start, it may be due to a broken timing belt or chain. The timing belt or chain is essential for the pistons and valves to function correctly. A broken belt or chain means that these components won’t move, leading to the engine failing to start.
In all these cases, it’s crucial to get the car to a service center for inspection as soon as possible. Ignoring these warning signs can lead to more severe and expensive damage, including possible engine failure.
Can a Broken Timing Belt or Chain Destroy My Mercedes Engine?
The answer is tricky as it depends on what type of engine you have. Interference engines can easily be destroyed by a broken timing belt, whereas non-interference engines are unlikely to be damaged from a broken timing belt. However, even with a non-interference engine, you should still follow your Mercedes’ recommended timing belt replacement cycle. If you’re unsure what type of engine your Mercedes has, the technicians at McCullough NAPA Auto Care can determine that for you and make recommendations for how best to repair or replace your timing belt.
