Schedule Cadillac 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 Cadillac. We’ve been in business since 1969 and have ample experience repairing and replacing timing belt systems for any Cadillac model, including the Escalade, XT4, XT5, XT6, CT5, CT4, and more.

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!

Graham is great. Kept me informed of my repairs and provided an accurate quote. Pleased with the results. Walked away feeling this place is trustworthy and does quality work. Found them through nextdoor app and now I see why they have such great reviews.

July 27, 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!

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!!!

July 1, 2020After 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!

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.

April 13, 2022I 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++++++

August 26, 2020Have 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!

May 16, 2022My 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!!!

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

May 4, 2021We had an issue with a splash shield dragging and overheating. We are heading back to Kansas this afternoon. They were able to fit us in despite being super busy & do a quick fix and sent us on our way in 10 minutes. So kind and amazing service!

June 18, 2022Able 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!

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 Cadillac 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 Cadillac’s 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 Cadillac 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 Cadillac’s recommended timing belt replacement cycle. If you’re unsure what type of engine your Cadillac 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.
