My daughter's car overheated just outside of Longmont, CO on her way back to school at CU Boulder. We called AAA Radiator the next morning and explained what had happened. My daughter was very worried about being able to get to class and work and the owner at AAA quickly understood the situation. So, they promised to work us in this week and that he should be done by Friday end of business. Today is Friday at 9am and they called to tell us the car is done and the radiator and work have a life-time warranty. Anything ever happens or we have issues with the radiator, just bring it back. Very thoughtful and professional radiator experts!

I took my 1999 ford van in with a leak that I could not determine where it was coming from, the guy quickly diagnosed that my problem was a leaking heater core. He quoted me a very reasonable price to replace it and did it the same day. I will definitely be recommending this shop to all my friends and family. Thanks AAA.

It's funny now reading the only other review on here and reading that they were only charged $75 to get their radiator fixed when I just went in and they charged me $685 to replace my radiator and a bent piece. On top of that, the guy wanted to charge me an extra $20 dollars at pick up for "installation" what a rip off this guy is. He took advantage of me and my situation just after the holidays. I will not be recommending this guy to anyone and hope that people read this review before going to his shop. If I could, I would give him zero stars. By far the worst mechanic experience I have ever gone through.

Brought in a very old tractor radiator. It was too far gone to repair. I had previously searched the internet myself and finding nothing AAA radiator took on the job. A couple hours later they located a perfect replacement for my old machine. Ordered it to the store and double checked fitment. very thankful for the time and effort they put in to help me.

Hard to find anyone who will test radiators...or heater core as was my case. Got pointed to AAA. Called him up, he said he would take a look at it if I came right in. I did and he did, and found nothing wrong. Did not charge me anything even though he spent 20 minutes. Seems like a nice guy who has found a niche.

I could not find a replacement radiator for my classic car. I took the radiator to these guys and they told me that they could totally rebuild my radiator. They gave me a quote and I told them to proceed with the recore. I got the recored radiator back and was extremely impressed with the quality of the work. The radiator that they built for me cools my car better than the old radiator did. I would highly recommend this shop. They are honest and reliable.

Had a weird issue with a radiator that I bought here less than 2 years ago, and AAA swapped it out and helped with my issue. They were easy to work with and helped get my van back on the road without issues.

I am glad we resolved your issue. If we can help you with anything in the future please let us know.

I took my truck into aaa to have my radiator checked, the guy quickly diagnosed my problem and gave me a quote that was several hundred dollars cheaper than the dealers quote. I will definitely be back and will be recommending this shop to friends and family.
