The Power Behind your Engine (Alternator Diagnosis and Repair)

There's nothing like that sinking feeling when you turn the key and nothing happens in your vehicle.  A lot of us are quick to blame the battery.  But it may instead be your alternator that's failing. Your battery supplies power to start your vehicle, but the alternator is what sends power when your engine is running.  The good news is alternators last a fairly long time, and it's not unusual to get seven years out of one. But they can give up the ghost thanks to the harsh conditions in the engine compartment. Alternators have bearings inside them that keep things turning smoothly.  Debris, liquid, dirt and more can team up with the high temperatures your engine generates to cause those bearings to seize up.  That's not good, and if that happens, you may even be able to hear the bearings grind. Other symptoms of a dying alternator are a squealing noise in the engine compartment or your headlights may go dim and bright, dim and bright.  You might even notic ... read more

The Byte Stuff (Your Vehicle's Computers)

Nobody has to tell you that computers are a part of so many things in our lives.  Smartphones, kitchen appliances, vacuum cleaners, televisions.  You name it—it has a computer in it.  And your vehicle is no exception. The earliest cars relied on the technology of their time, and there was no such thing as a computer.  But now, it's not unusual for a vehicle to have as many as 150 computers in it. They perform a variety of functions. An important one is diagnosing your vehicle's problems.  There are various sensors throughout modern vehicles that measure thousands of data points.  When something is not working correctly, they send a signal to another computer that stores that information. The data can be read by someone who has a special computer that plugs into a port in your car.  It displays certain codes that help technicians track down the culprit.  But it's not just the diagnostics that are computerized.  Everything from your vehi ... read more

'Tis the Season (Tires)

We all know about winter tires.  But did you know there is such a thing as summer tires? Most people have all-season tires on their vehicles.  They work pretty well in a variety of weather conditions.  But if you want better handling and performance, you might consider switching to summer tires.  Here are a few things you should know about them. Summer tires are good for high-performance vehicles like sports cars and luxury SUVs, but they don't have to be limited to those. They have a different tread pattern than all-season tires, with generally shallower grooves and more rubber that contacts the road.  The rubber is made of a stickier compound good for taking corners at higher speeds.  Plus it is engineered so it stays firmer the hotter the temperature gets.  Here's a bonus.  That design also works well in warm, wet weather.  It makes sense, since more the more rubber that's touching the concrete or asphalt when it's slippery out, the bette ... read more

Steering Clear in San Diego

Those who know vehicles believe the steering system may be the most vital component of them all. Perhaps you've found over the years your steering has gotten loose. Or maybe suddenly, your steering wheel has gotten very hard to turn. Let's steer you in the direction of understanding why this may be happening. First, loose steering. This can likely be the result of wear and tear on the components that connect the steering mechanism with the wheels. Those parts can be ball joints, Pitman arms or tie rods. These parts take a lot of abuse on the road, thanks to railroad tracks, potholes, uneven surfaces: you name it. It's important that they be checked regularly and maintained at John's Automotive Care. Second, the hard-to-turn wheel. Virtually all vehicles on the road have power steering. There are a couple of different types, though, so let's deal with each. By the way, when they fail, your vehicle's steering can suddenly go from easy peasy to really hard to control. Some vehicles have h ... read more

Suspension Service in San Diego at John's Automotive Care

When they hear the word suspension, many drivers in San Diego may think back to those energetic days of grade school. Well, your vehicle's suspension is actually a good thing because it keeps your vehicle up off the road and helps provide a comfy ride around San Diego. Its job is to keep your wheels firmly planted over bumps and through curves. Your suspension system has many parts. If you look under your vehicle, it's basically everything that connects your wheels to the vehicle's frame. These are heavy duty parts that do a lot of work. They need to be inspected for damage and excessive wear at least once a year. A good time for this is when you get your annual alignment service at John's Automotive Care. Here are some warning signs of suspension problems: the car pulls to one side it wanders the steering is erratic you see uneven tire wear you experience a poor ride or handling you see oil leaking from shocks Basically, you just don't feel in control when you ... read more

THE IMPORTANCE OF VISIBILITY (Cleaning Vehicle Glass)

We've all been through it. The vehicle ahead of us kicks up mud, slush, snow or salt on our windshield and we can't see a thing.  And not being able to see a thing when we're driving?  Not a good thing. Debris on a vehicle's glass can be blinding when driving directly into the sun.  And other things can ruin visibility: scratches on the glass, fogged windows, mineral deposits.  So lets make one thing clear:  Your windows.  Here are some tips. Number one rule, don't use abrasives on glass. That means no gritty cleaners that are made for metal.  Avoid at all costs those dark green abrasive pads on some kitchen sponges that are made to clean metal pots and pans UNLESS the manufacturer specifically says they can be used on glass. Use the appropriate cleaner for the substance that's being cleaned off. Special automotive glass cleaners are available, and your John's Automotive Care service advisor can make recommendations. Vinegar can work wonders. Sometim ... read more

Shake It up in San Diego!: Why Wheel Balancing

Our vehicles are not massage chairs. While we may enjoy a good vibration in an overstuffed recliner, we generally want as smooth a ride as possible in our vehicles. One way to achieve this is to keep a vehicle's wheels in balance. When a tire is mounted onto a wheel, it is usually out of balance. This means that as the wheel spins, there is a slight wobble to the path of the tire. For best handling performance and safety on the road, San Diego drivers want to minimize this wobble as much as possible. So we balance our tires. To balance a tire, your technician at John's Automotive Care spins it on a machine or drum to determine where it is off-balance. He then attaches weights that counter-balance the uneven weight. Most people in San Diego are surprised at how much balancing improves the smoothness of their ride. High-quality tires generally hold their balance well. But over time, wear and tear take their toll and tires can become unbalanced. San Diego drivers ca ... read more

The Economy of Maintenance for San Diego Drivers

Do I keep my old vehicle or buy a new one? It's a question most San Diego drivers ask themselves at some time or another.Generally, what it comes down to is the choice between a car payment and the possibility of repair bills. Most of the time, we want to choose the car payment because we don't like the inconvenience and uncertainty of vehicle repairs. But that payment has a detrimental effect on our budget and bank account.Edmunds.com is a great website to help you with your decision. This site uses repair histories to calculate the average repair bills for specific makes and models of cars. You can plug in the information for your vehicle and get an estimate on what it will probably cost you to continue owning that vehicle.Now, Edmunds.com isn't a crystal ball. It can't know what will happen to your specific vehicle. But it can guide you in knowing how much money to budget for the repair and maintenance of your vehicle ... read more

An Oil for All Seasons (Engine Oil Selection)

You swap your winter boots for flip-flops in the summer.  Why not change your winter engine oil for summer, hot-weather oil?  While it may seem like it makes sense, there's some good news.  Most drivers don't have to, and here's why. Engine oil can be made in different thicknesses.  That thickness is called viscosity, how easily it flows.  Now, it makes sense that the hotter it gets, oil gets a little thinner and doesn't lubricate as well.  So if you used a thicker oil in the summer, it's logical that it would protect better in the hotter weather.  While there was a time when oils could be only made in one viscosity, times have changed.  Using an ingenious formula, oil can now be created that changes its viscosity (called "multi-viscosity") as the temperature rises and falls.  It self-adjusts to match the conditions.  Now that's what I call a great invention. In most temperate climates, you don't have to swap out the type of oil you use ... read more

A Door No One Can Step Through (Fuel Door Repair and Maintenance)

Your vehicle has lots of doors including that one usually near the back on the vehicle's side.  That's the fuel door, something you use every time you gas up.  These endure hundreds of open-and-close cycles, usually without any problems.  But when they act up, it can be a major inconvenience for you. When they stick in the "open" position, it can present real dilemma.  You can still pump your gas, but do you just drive around with that flap sticking out the side? What happens if someone steals the gas cap or it gets damaged? What happens if it rains? Yep, it's decision time. A fuel door that sticks open can be due to a number of factors.  The hinge on the door may have broken, possibly from corrosion or it may have been hit sometime.  Some vehicles have a cable that operates the door and it could be loose.  The latch that holds the door shut could have broken or it, too, could be bent from something hitting it.  You probably want to take care of ... read more
