Industry Info

Follow basic maintenance tips to help keep your car on the road and out of the repair shop. Auto repairs are sometimes inevitable, but by consistently taking care of your car’s most basic parts and systems, you can often avoid common wear-and-tear problems. Consider the following tips for effectively maintaining your vehicle:

Tires
A car tire inflated to 35 pounds per square inch (psi) can lose one psi every month or for every temperature change of 10 degrees Fahrenheit. Find the recommended psi level in your owner’s manual or on a sticker on the driver’s side door jamb. Rotate tires every 6,000 miles to prevent uneven wear and have the alignment checked if the car pulls to either side while driving.

Engine oil
Follow your vehicle’s manufacturer guidelines to determine how often you should change the oil—typically, it’s every 3,000 to 4,000 miles, or three to six months. Cliff Do, owner of A1 Performance Auto Repair in Sunnyvale, says this rule varies with the type of oil your car requires. “With the new synthetic oils, you can go 7,000 to 10,000 miles between changes. Either way, make sure you don’t go too long without an oil change, because you risk damaging your car.”

To check your car’s oil level, park on a level surface and turn the engine off. Open the hood, remove the dipstick, wipe it clean with a cloth or paper towel and return it to the oil reservoir. Remove it again to see if the oil level is within the acceptable range marked on the dipstick. If you have to add oil, make sure you don’t overfill—too much oil can damage the engine.

Transmission fluid
Look for a reservoir marked ATF (automatic transmission fluid) and follow the same steps as monitoring the oil level—only this time, keep the engine running. You should change transmission fluid every 30,000 miles or so, but follow the manufacturer’s recommendations to be certain.

Engine coolant
Most engine coolant or antifreeze should be replaced every 30,000 miles (two to three years). Newer formulas, however, can last up to 50,000 miles. To check the coolant level, turn the car off and wait for the engine to cool. Locate the coolant reservoir (usually a translucent plastic tank) and check the level of the coolant against the full and low indicators.

Power steering fluid
Power steering fluid should be changed every three years or 50,000 miles. If your car has a power steering fluid reservoir, check the level visually; otherwise, follow the dipstick method. Low power steering fluid may indicate a leak, so have your mechanic take a look.

Air filter
Change your air filter every 12,000 to 15,000 miles. A clean air filter can improve gas mileage and reduce harmful emissions.

Fuel filter
Replace the fuel filter every year to help prevent debris from clogging your car’s fuel line.

Windshield wipers and wiper fluid
Windshield wiper care is one of the most neglected basic car care tips. Replace the wiper blades every six to 12 months or whenever the rubber becomes worn. Check the wiper fluid reservoir every week or so and keep it full.

Headlights and brake lights
With your car turned on and parked, have someone walk around to confirm all your lights are working—headlights, brake and tail lights, turn signals, etc. Replacing bulbs in modern vehicles can be a challenge, so consider having a mechanic do the job (especially replacing and aiming headlights). A mechanic will also know the difference between a blown fuse and a burned out bulb.

DIAMOND CERTIFIED EXPERT CONTRIBUTOR ADVICE & TIPS FROM Cliff Do

Expert CONTRIBUTOR PROFILE
  • Cliff Do is a 26-year veteran of the auto repair industry and owner of A1 Performance Auto Repair, a Diamond Certified company since 2004. He can be reached at (408) 827-8949 or by email.

Cliff Do: A Dynamic Development

By James Florence, Diamond Certified Resource Reporter

SUNNYVALE – Cliff Do’s career as an auto repair professional started small, but it developed gradually as he worked his way up from the basics to the big leagues. “I’ve loved auto repair since I was a kid,” he says. “As a teenager, I worked on motorcycles and scooter bikes, and from there I moved to diesel and gasoline engines. I was never satisfied doing just one thing; rather, I wanted to learn how to work on all types of cars, from domestic to European and Japanese. So, that’s what I did!” To increase his knowledge and achieve his occupational goals, Cliff attended Skyline College in San Bruno and earned his ASE Master Certification. In 2000, he established A1 Performance Auto Repair in Sunnyvale, where customers continue to benefit from his extensive automotive expertise.

Originally from Vietnam, Cliff came to the San Francisco area in 1990, where he still lives today with his wife, Jennifer, and their children, Stephen and Tristan. Cliff loves living and working in the Bay Area, not least because certain aspects of it remind him of his home country. “The weather here is similar to where I’m from,” he says. “There’s also a great community—a real melting pot. The people are very friendly and there are great schools and other community resources.”

As a business owner and family man, Cliff’s daily schedule is usually packed, but he says he doesn’t mind too much. “Most of my time is spent running my shop and being with my family, but since I love what I do and I love my family, that’s not such a bad thing.” When Cliff does get some free time, he likes to take advantage of the lush Bay Area surroundings by fishing in the bay and hiking along the San Francisco skyline.

Looking back on his life and career, Cliff cites hard work and determination as essential ingredients of his success. “In order to better yourself and accomplish your goals, you have to work hard,” he says. “Coming from a very poor family, I had to take things into my own hands and apply myself in order to get where I am today.” However, while Cliff’s resolute mentality was instrumental in achieving his accomplishments, he also acknowledges the shaping influence of the people in his life, which is why he says after retirement he’d like to give back to his community. “I would get involved with doing some volunteer work and just help people in need. I would also take care of any needs that my own family may have.”

Ask Me Anything!

Q: What was your first car?
A: A 1978 Toyota Celica. I bought it for $300 and it lasted four years.

Q: What’s your favorite movie genre?
A: I like kung fu movies.

Q: What were you most known for in high school?
A: Being a leader. I’m good at running things, organizing people and counseling them.

Q: Q: If you could drive any car, what would you drive?
A: I like German cars, so any kind of BMW or Porsche would be nice.

Q: If you could live in the city or the country, which would you choose?
A: I don’t want to live in the city, but I like being near it, so if I could live in the country about 5 or 10 miles outside of the city, that would be ideal.

Q: What’s your favorite season and why?
A: Spring, because the weather is so fresh and clear and the flowers are in bloom.

  • How to Tell if You Need New Brakes

    SUNNYVALE — Brakes are one of the most important components of any vehicle, which is why it’s vital to proactively maintain them. A crucial part of brake maintenance is being able to tell when they need to be replaced altogether.

    To take the guesswork out of brake replacement, some modern cars are equipped with brake pad wear sensors. Mounted on the brake pad and routed through the caliper, this sensor warns drivers if the pad is becoming excessively worn and needs to be replaced, usually by triggering a warning light on the vehicle’s dash. However, not all vehicles are equipped with such warning devices, which is why you should have your brakes inspected on a routine basis.

    If you notice your vehicle’s stopping time seems to be increasing or you have to press harder on the brake to come to a stop, these are good indicators that it’s time to get your brake pads changed. Ignoring these warning signs can result in potentially dangerous consequences, whereas promptly addressing brake issues will ensure better safety for yourself and others on the road.

Expert video tip
  • Video: Caring for Your Brakes

    Complete Video Transcription:

    SUNNYVALE — Host, Sarah Rutan: Depending on the type of car you have, there are a couple of ways to tell when its time for new brakes. Today we’re in Sunnyvale with Diamond Certified Expert Contributor Cliff Do of A1 Performance Auto Repair to learn more.

    Diamond Certified Expert Contributor, Cliff Do: Yeah, we talk about the brakes. So, here the brake disc and the brake pad inside. And some car, they have like more than pads and discs; they have the sensor. So, if you want to know the brake pad is worn out, they have the sensor inside. So, when the sensor lit up at the dash, you know that a brake is worn out.

    But somehow, like a Japanese car, they do have the sensor in the brake pad. They don’t have the light. So, some sensors is attached to the brake pad right here. So, and then when the brake pad is worn out, you know, low like this, the sensor will touch and will make a noise. Here, that the new pad. You can see the difference on the brake pad. So, that one new and one old.

    So, when the brake pad worn out like this, so you need the new brake pad replaced and make the car safe running on the road. And beside [the] brake pad, [a worn out [unintelligible] disc], it get into very dangerous [points]. So, the brake pad can be malfunction and brake system could be malfunction and get, you know, [out order] on the brake. So, please check the brake out and make sure that they’re safe.
