Alternator, Starter & Car Battery Replacement Services


Alternators
Your alternator powers essential systems while your engine is running. If your lights dim or your battery drains unexpectedly, it may be time for alternator repair or replacement. Our expert team will test your alternator and get you back on the road safely.

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 Sunnyvale. 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
The starter gets your engine going. Clicking sounds or a failure to start can signal a faulty starter motor. We'll diagnose starter issues and repair or replace the component as needed to ensure reliable starts every time.


Battery Related FAQs


What can go wrong when jumping a car?

Incorrect jumper cable placement-reversing polarity-is a leading cause of alternator or battery damage. Use red for positive and black for negative, and never let the clamps touch. Damaged cables or corroded battery terminals can also pose a risk. For peace of mind, let De Anza Auto Repair perform the jump safely.

What precautions should I take when replacing a car battery?

Use insulated tools and avoid shorting the terminals. Handle the battery carefully to prevent drops or tipping, and always secure it before reconnecting the cables. If you're not familiar with replacing a car battery, let our trained team handle it with precision and care.

Car Starting Related FAQs


How do I release a locked steering wheel?

Place your foot on the brake and turn the wheel in the direction in which it has a little range of motion. This should ease the tension in the steering column and allow you to turn the key. Turning the key unlocks the steering wheel. Do not try to unlock your steering wheel without a key or if the battery is dead. This should only be done by a professional auto repair technician.

What are the warning signs of a bad starter?

A failing starter may click when you turn the key or produce a slow whine. In some cases, there may be no sound at all. If your car won't start and the battery is healthy, it's likely time to inspect or replace the starter motor.

Went here to fix my Turo car. April had been very helpful through and through! She helped with the insurance process and has made it seem less for me. Would recommend and come back again!

April was very helpful to my daughter and her Porsche, Boxster. So, when my Prius had problems, I knew who to turn to. It turned out to be a serious problem (head gasket) and both April and Mo's brother John were sensitive to the many issues a retired older person on a fixed income has. They still provided excellent service, treated me with respect and worked with me to find a mix of what I could afford, without compromising the necessary repairs. I felt like I had gained family by the time I got my car back. So, when our Lexus had problems and left me stranded in Auburn, California, I knew who to call -- April worked with me to get the engine codes, run them through her mechanics, determine where I could go locally to find out if it was safe to drive it home and April kept checking up on me -- her last call was well after their closing hours when I had been cleared and was driving it back to their shop. I feel like they really care about people they are not just fixing cars. I am a customer here for life.

I recently had my car serviced at De Anza Auto Repair and I was extremely impressed with their honesty and fair pricing. The customer service was phenomenal, with the staff being friendly and knowledgeable. They explained everything to me in detail and even gave me some tips on how to better maintain my car. Overall, I highly recommend De Anza Auto Repair for their exceptional service and great prices.
