McCullough NAPA Auto Care

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 Dunwoody, 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.

  • My 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!!!

    Able 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 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!

    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%.

  • 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.

    After 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!!!

  • Very respectful, honest, and professional. I was having issues with my headlights, and they fixed it for a reasonable price. They do a lot to ensure that you have a positive experience, and that you're not wasting your money on unnecessary parts or repairs. Top notch service, A+!

    I 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.

  • Came in for emissions and they exceeded my expectations! Saw headlight out, replaced it. Saw no oil sticker, checked it and put a little in it until i can get back in for change. While waiting you could tell these guys really care about their customers and the safety of their vehicles. Definitely will be coming back here!

  • Eric at McCullough has been taking care of my family's [multiple] cars for over 10 years now. A Volkswagen, a Nissan, and 2 Acuras: They've done minor repairs all the way to major transmission replacements. Eric is trustworthy, honest, and tells you what really needs to be done versus what can wait. Their prices seem reasonable (although in fairness I haven't been anywhere else recently b/c I'm so pleased with them), they are timely, and always communicate what the car needs in detail. I can't recommend these guys enough!

    Eric has been my service manager for years. He is always professional and easy to deal with. He goes out of his way to take care of your needs and makes accommodations to the customer when needed. They will ferry me and my car to and from their shop (I live within blocks) and I appreciate that very much. Everyone at McCullough is nice, friendly and helpful.

  • 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!
