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 mistake is reversing the jumper cable connections. Always connect red to positive and black to negative. Using low-quality cables, allowing the clips to touch, or attempting to jump-start 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, as this can create a dangerous short circuit. Never drop the battery, and do not reconnect the cables until the battery is securely mounted. If you're unsure about the process, let our technicians handle your battery replacement professionally.
Car Starting FAQs
How do I unlock a locked steering wheel?
Press the brake pedal and gently turn the steering wheel in the direction it moves slightly while turning the key. This relieves pressure in the steering column and allows the wheel to unlock. Never force the wheel or key. If the battery is dead or the key will not turn, consult a professional technician.
What does a failing starter sound like?
Common signs of a failing starter include a single clicking sound, grinding noises, or complete silence when turning the key. These symptoms often indicate a starter problem that should be inspected and serviced as soon as possible.

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!
I am a long time customer. On 3 separate occasions I had a dealership tell me that I needed extensive repairs. When Gary's looked over the vehicle they told me the repairs which were recommended were not necessary at that time!! I don't know any other repair shops which would do this!! Can't recommend them enough!!!
