Alternator, Starter & Car Battery Replacement Services


Alternators
An alternator is an automotive device that converts mechanical energy to electric energy (ac) and provides charge to the battery when driving. An alternator is an important part of your car, so its failure would translate to your car's failure. When your car's alternator develops problems, seek expert help. At Gary's Full Service Auto Repair, we have experts who can handle all your alternator needs to get you back on the road - quickly. Visit Gary's Full Service Auto Repair today.

Batteries
Your car battery powers everything from the ignition to headlights. If you're jump-starting regularly or seeing a dashboard warning light, it's time to consider a car battery replacement. Our team offers fast battery testing, replacement, charging, and recycling services in Aurora. Not sure how often to replace a car battery? Most drivers should check their battery after 3 years and consider replacing by year 5-especially in extreme climates or with frequent short trips.

Starters
A starter is a motor (electric, hydraulic or pneumatic) that rotates the internal combustion engine to initiate the engine's operation. Starters are important parts of your car's engine and their failure would translate to your car's failure. When your car's starter develops problems, seek expert help. At Gary's Full Service Auto Repair, we have experts who can handle all your starter needs to get you back on the road - quickly. Visit Gary's Full Service Auto Repair today.


Battery FAQs


What are common mistakes when jumping a car?

The most common error is reversing the jumper cables-always connect red to positive and black to negative. Using low-quality cables, letting clips touch, or jumping a battery with visible damage can cause serious electrical damage. When in doubt, have Gary's Full Service Auto Repair perform the jump safely.

What should I be careful of when replacing a car battery?

When replacing a car battery, avoid touching both terminals with the same tool-it can cause a short. Don't drop the battery or reconnect cables before it's securely in place. If you're unsure, let our technicians handle your car battery replacement professionally.

Car Starting FAQs


How do I unlock a locked steering wheel?

Press the brake and gently turn the wheel in the direction it moves slightly while turning the key. This relieves pressure in the column and allows the wheel to unlock. Never force it-if the battery is dead or the key won't turn, consult a professional technician.

What does a failing starter sound like?

Common sounds include a single click, grinding, or even silence when turning the key. These signs often indicate a starter issue that requires immediate inspection and service.

What our clients are saying about us

We have established longterm and stable partnerships with various clients thanks to our excellence in solving their automotive needs!

Joe and Kirsten were very honest and straightforward about the price and procedures of what they were doing to my Japanese import. Vehicle safety was their number one priority. After being turned away by several 'full-service' Toyota garages that claimed my car’s issue was too complex or outside their scope, Joe diagnosed the problem immediately and handled the repair with total confidence. It’s rare to find a mechanic with this level of technical expertise and problem-solving ability. If you have a job that no one else seems able to fix, save yourself the stress and bring it here first. Truly a master of the craft! quotes-image

I've been going to Joe and Kerstin for awhile for my 2014 Chevy Equinox, which has been a relatively solid car despite the model's notorious problems (burning oil, especially). They recently checked out the car before I had a road trip and gave me a couple of "yellow flags" that could wait awhile but said I should be good to go, including my brake pads. My sister was driving the car into Santa Fe when she said the car was shuddering when she braked. Worried we were about to have something really bad happen, I pulled into a local place. Welllll…they totally swindled me: new pads, warped rotors, a torn boot, all sorts of stuff. The car was about to fall apart and strand us in the desert, clearly. Eager to move on to my next destination and not be stuck, I reluctantly gave them my credit card. I texted with Kerstin and let her know what happened. She called me back right away and explained in no uncertain terms that I was to go find a second opinion and not pay for anything (whoops, too late…I guess it's a norm at a mechanics not to pay for anything up front, unspoken rule). She checked with Joe about the recent diagnostic and talked me through the possibilities of what was actually happening with my car and supported me going up there and requesting a refund and only paying for what had been completed (new brake pads and rotors in back, still a ripoff for probably fine rotors and pads that were at 3.5mm but a more doable one). Yes, I felt like an idiot. Yes, initially they refused the refund and "had to call corporate", blah blah blah. But I probably saved $1700 in the process. Then, Kerstin stuck with me for doing basic troubleshooting for the shuddering. Joe proposed that it could be "bad gas", at one of the random stations we'd stopped at. He said that we could test filling up the balance of the tank with high octane Maverick gas (no ethanol). Would you believe that did the trick? All the car's symptom's disappeared (turned out it hadn't been shuddering upon brake, just shuddering in general). I completed my road trip without any issues and soon after went back to Gary's for a different test (discussed awhile back before all this went down for my aging car). They double checked the shady mechanic's work and said that they saw very little that needed addressing, and certainly nothing in the thousands. The car has driven fine since then. Anyway, highly recommend Gary's. They stand by their work!quotes-image
