A radiator is one of the car engine’s main cooling system components. The radiator works to eliminate heat in the engine by keeping your coolant cool. It will disperse a mixture of coolant with water through its fins to exchange the heat with the air that moves through the radiator. A failing radiator can cause an engine to overheat and malfunction.
When you need radiator repair or replacement in Marietta, Georgia, contact McCullough NAPA Auto Care to diagnose and troubleshoot any problems with your radiator and cooling system.

Signs Your Vehicle Needs Radiator Repair or Replacement
A malfunctioning radiator can lead to all sorts of mechanical issues within your car. The job of the radiator is to keep your engine from overheating. Here are the signs that you have a bad or failing radiator.
1 – Your Engine is Overheating
The radiator is the only component designed to keep your engine cool. If your engine is overheating, especially under normal driving conditions, then you have a failing radiator. The cause can range from low levels of radiator coolant to entire radiator replacement.
2 – Sludge Build-Up in your Radiator
Radiator fluid is usually green, yellow, orange, or pink. Discolored or rust-colored coolant is a sign of sludge build-up within the radiator. These contaminants can greatly impact cooling performance.
3 – Leaking and Low Levels of Coolant
Do you constantly find yourself needing to add coolant to your radiator? Perhaps you notice a pool of green, yellow, orange, or pink liquid on the floor beneath your car after it’s been parked for some time. Whether it’s the radiator itself, or a problem with the engine block or a hose, a coolant leak is a sure sign that your radiator needs repair. Our shop can perform a pressure test on your radiator to determine the cause of the coolant leak.

July 19, 2020We 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, 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.

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, 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.

May 16, 2022After 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!

July 28, 2021I have used McCullough Auto Care for more than10 years. I needed a reliable auto maintenance service because I commuted weekly to Birmingham. One of the nice things about these guys is they listen when I mention an issue with the car, go over their inspection results of my car and review my bill in detail. I have never been disappointed in their service or the cost of the service I received.

My parents and I have been taking our cars there since the beginning. Great, hardworking guys. The only mom and pop shop left in Sandy Springs.

January 2, 2022They figured out the issue with my Pathfinder and made the repair quickly. Eric is very thorough and kept me up to date the entire time. This was my first time using them but I will use them again!

October 21, 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!

I have recommended McCullough's several times to my neighbors in the neighborhood blog. I have used this company for many years and they are always helpful. It is great to have a garage you can trust.

January 25, 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!

December 1, 2020Graham was great and was up front about everything that needed to be done. My son's jeep went down on the Saturday before Memorial Day and they had him ready around 1pm that Thursday. Quick turn around in my eyes. Nice employees, everyone was cordial and friendly.

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.

February 15, 2021Graham 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, 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!!!

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, 2019I 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++++++

April 29, 2020This 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.
