Let’s address a very important maintenance item – timing belt replacement. Timing belt replacement is important because letting this one slide 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 the right time to let in air and fuel, they close at the right 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. McCullough NAPA Auto Care stocks various timing belts and offers timing belt replacement near Cumberland, Georgia.

Schedule Timing Belt Replacement Service in Cumberland, GA
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. Contact us below to learn more about timing belt replacement or preventative scheduled maintenance.
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 timing belt or timing chain needs replacement.
- Ticking or rattling in the engine
- Engine misfires
- Visible wear and tear
- Engine won’t start
- Metal shavings in engine oil
Can a Broken Timing Belt or Chain Destroy My 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 vehicle’s recommended timing belt replacement cycle. Contact McCullough NAPA for your timing belt replacement service. We are located near Cumberland, Georgia.

This place is exactly the kind of service you come to expect. Great service, timely, and they never assume I don’t know what I’m talking about because I’m a girl.

November 12, 2021Got me in the same day and kept me up to date. Fixed what was needed and did not push any costly add ons like other places do. Feel like I can trust these guys.

January 20, 2022The team at McCullough Auto Care are so friendly, thorough, and timely. They know the cars bumper to bumper and how to properly diagnose the problem as well as do scheduled maintenance. They really work with you to do what is necessary to make your car safe and not hit your wallet too hard! I can say that I trust Eric and his team with our cars.

I 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.

September 10, 2019McCullough 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.

December 3, 2021A staff of gentlemen ready to answer every question with a smile and great knowledge. They not only gave me a good estimate but they completed the work a day early! I highly recommend McCullough NAPA Auto Care to you. You will not be disappointed by the care they put into your vehicle.

This place is right by my house. I was really happy with the customer service. I was worried about affordability and turn over but they were efficient and I will be back for any future needs.

August 30, 2020I 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.

Eric was amazingly helpful to work with. Great communication around the whole process. He was great about calling out things that could be done without being pushy about doing them. Would highly recommend!

February 27, 2021Great 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!

This shop is the best. They did everything they could so I would have minimal time without my car such as having all parts ready before they scheduled the repair. They are super nice and no surprises on price. They opened up my bumper and found a part was damaged. They could have left it the way it and no one would have known but they were honest and did the right thing. I recommend 100%.

July 24, 2019We 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.

November 21, 2021After recently moving to the area, I had a vehicle emergency where my transmission needed replacing. Graham immediately took me in and was SO kind, professional, and direct about the costs; one of their kind staff members even drove me home after my car was dropped for repair so that I did not have to call a car service. They were so patient with me and got my car back to me in one day completely fixed and ready to go! I will never use any other automotive repair shop in the area! ABSOLUTELY recommend without hesitation!

Wow! 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, 2021Able to fix issue with my 2011 truck other shops could not address- very hard to diagnose mechanical issue another reputable shops couldn’t figure out. Good prices, done on time, and with expert mechanics. Will have them work on all of my vehicles and highly recommended. Support a family owned business for a change!

February 23, 2021Had 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

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.

January 11, 2021Eric and everyone at the shop is fantastic. I call and they are so kind and accommodating. No wonder they have so much business!!! Despite the amount of customers they have, they treat everyone with respect and attention. Love doing business here. Could recommend more. Fast, excellent service !! -Alexa

June 18, 2022I 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!

They diagnosed and repaired my car in time for my trip. Car works great! Eric provides excellent customer service even when he's got a ton on his plate.
Gavi Shapiro
May 10, 2022Always 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!
Robyn Vogel
May 14, 2020I 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.

January 23, 2020Good, honest, and fair shop. If you are in sandy spring, I would not go anywhere else. Family owned and operated - take care of their customers and their crew it seems. 6 stars

January 23, 2020My truck broke down when we got to Atlanta on the way to Disney world. A local stopped to help us and recommended this place. This place got me in and got the radiator fixed for a very fair price and on our way the next day very quickly. I was so impressed and it's no surprise they are very busy. Thank you so much and my family all got to the resort and is having a great time!! These people are great and will get your vehicle fixed for a fair price. Plus, you get Napa warranty all over the country at least I did on the repair I got. Please support them!!!
