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.

  • I had a check engine light on Saturday afternoon, ended up being an engine coil pack needing to be replaced. It was obviously super busy and I knew I would need to leave it until Monday to get looked at. Staff was very informative and communication was excellent. Got it looked at Monday and ordered necessary part to come in the next day. Went ahead and did the spark plugs as well since I was nearing 60k miles. Picked it up after lunch with no issues. Seems like they do really well with the small space provided and very busy area right off 285

    Had experienced front tire damage hitting metal debris on I-285 just before Rosewll exit. Immediately exited on Roswell and saw NAPA sign and pulled in. Place was busy! But got attention immediately by Jeff service worker. Got tire off my car no waiting. Wow! Determined rim bent but tire still good. He could have sold me a new tire and i would have not known better. So appreciative. Then met with Eric McCullough and quickly arranged to have rim fixed. I decided on new tires for safety and were worn. Eric got me great deal on tires and had my car fixed SAME day. Eric runs a super customer-focused operation. Kudos! Bruce Fike

  • My vehicle was on the verge of breaking down while I was in Sandy Springs for work last week (I live in a different town), and my boyfriend had determined that it was a problem with the alternator. He helped me find McCulloch Auto Care, which was right down the street. We'd noticed the good reviews, and we took a chance! The staff is super friendly, professional, and kind. They were able to confirm our suspicions about my car's specific issues, and took us as soon as they could. I was so impressed with their customer service. They really went above and beyond to meet my repair needs, had a fair price, and worked quickly to repair the issue. I almost wish I lived closer just so that I could have my car serviced here more often! Great family owned business.

    Eric 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

  • I may have written one other recommendation in my of 50 years, but after doing business with Eric McCullough for 35 of those years it is time to write another one. He maintained and serviced my auto's, my wife, kids and employees for 32 of those 35 years. He has stood behind the work on everything he and his employees have done. He operates his business with great honesty and integrity. I highly recommend doing business. with McCullough

  • I do not know if I can type out all that I want to in this review but let me say this. WOW!! Being a single father with a busy schedule I cannot tell you enough how grateful I am for Eric and his team! I have been taking my vehicle to them for over 2 years now and I would not go anywhere else. The honesty, timing and keeping their word every single time is simply priceless! They have saved me so much grief because of my current situation. For all you single fathers out there...these guys got your back! I only have one vehicle and my son and I depend on it being in the best running shape possible. Eric and his team go out of there way EVERY-SINGLE-TIME. During these special times where its harder to get even the simplest things done, that has not slowed down this business. They still give 110% with every customer and are sympathetic to their customers unique situations. People, don't look any further for a shop that you can trust and count on. You will simply waste your time and find no better service in Atlanta. Eric, I want to thank you from the bottom of my heart for everything you and your guys do. Having open and honest communication with you is always a pleasure. Folks lets do our best to keep these guys busy!! They deserve everyone's business! A++++++

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.

    I know for me one hard thing about choosing a mechanic is brushing off all previous notions I have about mechanics Potentially not treating my car how they would treat their own car. This place has done more than exceed my expectations. I got a phone call for every update, I got a thorough description of what was to be done and what was wrong, not only that, but where the dealership said it would take them two weeks to fix my car, these guys did it in less than 24 hours. I have never been happier to spend $300 in my life. Anything I need in the future, you can be sure I’ll bring it here.

    Great 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!

    Have been going to McCollough’s for decades! Once I found them, I knew they were honest and professional. Not often one can say that about an auto repair place. They have helped me keep my older vehicles safely on the road for longer than I could imagine. I have always been treated with respect, no matter how large or small the issue, which is excellent and reassuring for an older woman.Highly recommend them!

  • I 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!

    I 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.

  • I received great service from this location! I called them about replacing a serpentine belt and they got it done for me the very next morning. It was quick, and cheaper than some other places that I had called for the same service. Eric and his team did a great job, and they were very nice! I will definitely return for any other auto repair I may need in the future.

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.

  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. 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.
