The hottest temperature ever recorded is when Physicists at Oxford zapped a piece of aluminum with the world's most powerful x-ray laser, heating it to 3.6 million degrees Fahrenheit. Most likely you need a refrigerant recharge. But before we just add more refrigerant to your AC system we need to know why it's missing in the first place.
Chevrolet stepped up its brakes game with the 2014 Chevrolet Corvette Stingray Convertible. In just 90 feet it can go from flying at 60 MPH to a standstill. Now you can assume, not only does this Corvette have tip-top brakes, but they are well maintained. This all comes down to you as the driver, how and where you drive.
So first take a deep breath, yes it's true it could be something big like an expensive catalytic converter replacement or it could be something as simple as a loose gas cap. The great news is it's much more likely to be a loose gas cap. So first thing first, screw on that gas cap and turn your car on and off a few times and see if that fixes the problem.
At our shop, we have ASE Certified Technicians who can take on any engine auto repair job or diesel repair job, big or small. It is a common misconception that if you have a major repair, you need to take it to the dealer. However, with our shop, you get the best of both worlds. We want you to have complete peace of mind by both saving money and receiving our bulletproof warranty.
Most businesses utilize a fleet of vehicles to help things run smoothly. These vehicles offer a team of workers and specialists a way to get to clients and assist in the daily tasks that come with many service based companies. Keeping these cars running is essential to keeping a business running, which is why regular servicing is crucial.

Excellent service. Brought in my 2006 sprinter since it was making a rattling sound near the engine. They immediately diagnosed the issue which was needing a new harmonic balancer, and fixed it within 2 days of me bringing it in last minute. Honest and reasonably priced. Would highly recommend theses guys!

If you want mechanics that know what there doing, come here. Unfortunately, they will blow you off and keep making excuses of why they haven't even looked at your car to give you one of their high estimates. My experience was not a good one. I just told the girl that answered the phone, I can't wait anymore, and I was coming in to pick up my vehicle. When I got there the guy accused me of telling off their receptionist, and this is without finding out my side. Completely unprofessional!

Preston, Hank and Mitch are wonderful. The team at Callahan's have always taken care of my family when I need them. Even on weekends or late at night Preston has been there to answer my call when I have broken down. I refer every one to them when they have a need.

Preston and his team were amazing!! I had an airline leak on my air brake system on my RV. Preston send one of his mobile techs and they were there in less than 30 minutes. The tech found the issue, went and got the replacement part, installed the new line and tested and resolved the issue ASAP. From the time I called until they left was less than 4 hours and that included going to get the parts!
Job well done and I will definitely use Callahan's in the future for my repair needs.

I used this auto shop for a engine rebuild.
I bought the engine, had it shipped to auto shop.
Auto shop received engine, installed it.
8 months later engine goes out.
The company I bought the engine from had a 5 yr/100,000 warranty on engine, but I can't use it! You know why?.....Wait for it.... Wait for it.......
Because the auto shop did not send in the warranty after the install as required. #really

Auto shop refused to make it right, now I'm out of close to $5,000

Buyer Beware!

I was having some issues with my vehicle and was referred to Callahan's and did regret going there to have my car fixed. The owner and his guys were very up front, and were willing to walk me through and show me what exactly was wrong with my car. They gave me a great price and I would highly recommend this shop to anyone.

I can't say enough good about Callahan Auto without writing a short novel! My first experience was when my truck began making a strange noise and I just pulled into Callahan to see if they could help identify the sound. They had a mechanic hop right into the truck with me to drive around and duplicate the noise and had me back on the road in no time with my issues resolved. I've returned to them several times since.

Last week, I brought my truck in for routine brake work and when the wrong parts were delivered to their shop delaying my truck, they all stayed late working on it to get

We have used Callahans for quite a few issues with our cars but not anymore. The last few months we had been having some overheating issues and found that our thermostat that Callahans replaced was installed incorrectly. After all the money we put into repairs in this shop never again. I have attached a photo to show what it looked like.

This is the only place in town i would take my truck. I own a commercial vehicle and my business relies on us being on the road. Preston not only has extremely fast turn around time but also fixes problems once and for all. He's honest, trustworthy and goes above and beyond what's expected. These guys are so good not only have i built a great relationship with the company but truly consider these guys friends too. Best decision i've made is trying out Callahan Auto. Highly recommend Callahan Automotive

Finally an auto shop that is informative, easy going, non pressuring, reasonable price, and knows their stuff. This is that Lil gem we all search for. I drive a semi truck and I'm thrilled to share with everyone about my great experience with them because I'm sure you will too. Thanks guys for your awsome work.
