    This 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.

  • Always 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!

    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 own and automotive repair business in Jacksonville, but my wife lives in Atlanta and needed tires for her car, so I know good service and fair pricing in this industry. I chose McCullough because of their good reviews and they did not disappoint. They were very professional and took good care of my wife. I would highly recommend them and will continue to use them for her service needs.

    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!!!

    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.

    We 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!

  • Brian 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!

    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.

Signs Your GMC Needs Radiator Repair or Replacement

A malfunctioning radiator can lead to all sorts of mechanical issues for your GMC. The job of the radiator is to keep your engine from overheating. Here are the signs that your GMC has 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 you need radiator repair. Our shop can perform a pressure test on your radiator to determine the cause of the coolant leak.
