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 Johns Creek, 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.

December 19, 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.

March 10, 2020This is the best place you could possibly go to take care of your car! My family and I have been going here for over 15 years and we recommend them to everyone. Eric, Bryan, and Graham are the most trustworthy guys and truly care about their customers. We all love them and are so thankful we found them!!

Have 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 10, 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!

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, 2021Honest and fair price!!! I went in for 60k mile service. They said I only needed oil and cabin air filter changed. That is refreshing honesty! Saved me big bucks! This will be my new shop for my car service. ☺

Could not be happier with the service I received at McCullough NAPA Auto Care! The gentlemen that helped me were very professional and made me feel at ease in a stressful situation. Would definitely recommend!
Rachel Eichenblatt
July 1, 2020Would recommend to anyone that needs vehicle maintenance. They are the most honest and reliable mechanic service that I’ve dealt with. Thanks again!

February 16, 2021I 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.

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.

December 1, 2020I really cannot count the number of times these brothers have taken care of me, my family and all our various vehicles. We have been loyal customers for more than 20 years! They have done everything we have needed on cars, trailers, used car evaluations for purchase, tank drops, and all the basics. They are very trustworthy and will give you a honest answer on everything and a reasonable estimate on what it will cost to resolve it. They are super busy, so plan to wait a day or two longer than you might somewhere else, but it is worth it!

I have known Eric and the facility for over 30 years. The service from both a customer and repair stand point is excellent. You can expect to be treated with a high level of professional performance, and courtesy.
Mark Schacher
January 23, 2020Eric was amazing from start to finish. I chose this shop for my repair based on previous reviews & I'm glad I did. He made sure to, in my opinion, go above and beyond with his politeness, as well as helping to make the process smooth and to try to save me as many coins as he could, while still getting done what was needed. Very happy with this visit
LaDonna Mechelle
August 29, 2020What more is there to say? These guys are amazing. Their service is very thorough and quick. I was so worried about the cost of my repair but Eric and Brian put me at ease with their extremely reasonable prices! My truck is running like it's brand new again and I can't thank these guys enough!

WOW!! An amazing experience! Traveled here from Kansas to apartment shop for my daughter who is relocating and my husband was unable to join A part was dragging under the car so we popped in to see if they could help. They were so kind and helpful. Restored my faith in this world. Good people do exist!!
Angela Drybread
June 18, 2022I 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, 2019Had 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

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%.
Graham Reifert
July 24, 2019Came 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!

We 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.
