Water Everywhere (Clogged Drains)

It's bad enough when you mistakenly leave a window open in your vehicle on a rainy day and you find your carpet soaked.  But what in the world is going on when your windows are closed tight, not leaking and you STILL wind up with wet carpet? The answer could be something you might not even know your vehicle has. And the answer is? Drains. And those drains can get clogged.  Yes, your vehicle has several drains with tubes or hoses attached to them that you really never see.  There are some in and around the hood that channel rainwater down to the ground.  There are some that take condensation from the air conditioner and allow it to flow outside.  And if your vehicle has a retractable sunroof or moon roof, there are small drains at each corner that connect to tubes that go through the vehicle body down to an exit near the ground.  Considering all the leaves, dirt, dust and other debris your vehicle encounters on a daily basis, it's not surprising that these ... read more

Ethics of Automotive Repair in San Diego

We're going to be talking about the ethics of automotive repair. It seems like news outlets really like hit-and-run reporting; they hit everyone from groceries stores to retail to physicians. And the San Diego automotive service and repair industry hasn't been given a pass either.Unfortunately, every profession in San Diego has some bad actors that hurt the reputation of everyone else. On the automotive side, industry associations and professional licensing organizations are very committed to high ethical standards.Yet some people remain uncomfortable with San Diego automotive service and repair. It may start with the fact that our vehicles are a big investment and we rely on them for so much in our lives. That alone guarantees our attention. And how well we understand the recommendations really impacts our comfort level.If we understand what's recommended and the benefits of taking care of the work – and the pitfalls of putting it off ... read more

Getting from E to F (Fuel Gauge Problems)

Who thinks about their fuel gauge?  You probably don't… until it doesn't work any more.  Then you have to guess how much fuel is in your tank, and that's no way to live life on the road.  Fuel gauges, like every other part in your vehicle, can fail.  And when yours stops working, you will probably want to head over to your service facility soon, because no one relishes running out of fuel. The fuel gauge system is much more than just the gauge you can see on your instrument panel. Most systems have a float inside the fuel tank that goes up and down depending on the fuel level.  It's called the fuel sending unit, and it sends an electrical signal to the gauge (on the dash) telling it to display how much fuel is left in the tank.  So, what could go wrong?  Well, a few things.  For one thing, corrosion from bad fuel can cause it to stick and it won't move up and down any more.  So you could fill up your tank and the gauge would still rea ... read more

Plugging Away (Spark Plug Replacement)

If you drive a vehicle with a gasoline engine, thank the spark plugs for igniting the gasoline/air mixture in each cylinder that keeps your vehicle traveling smoothly down the road every day.  Your spark plugs work hard, firing thousands of times in a well-choreographed order, and you usually don't pay much attention to them until one of them stops working the way it should. Signs that spark plugs are wearing out include: Engine runs more roughly than it did Vehicle doesn't start as easily as it used to Vehicle hesitates when you press on the accelerator Your fuel economy has gotten worse When a spark plug stops working altogether, you will find your engine has likely lost a lot of its power and isn't running smoothly.  Your Check Engine light may  come on.  Then it's time to head to come to our service center to have it diagnosed. If your plugs need to be replaced, they're usually done all at the same time. And if your vehicle has spark plug wires, experts recomm ... read more

Lean Times (Shocks and Springs)

You may have noticed your vehicle going through lean times.  By that, we mean it's literally leaning to one side.  When you notice that, you should get it checked out at your service facility soon because you could have a serious problem. Many things can cause a vehicle to lean.  You may have problems with your struts, shocks or springs.  They all work in tandem to make your ride more comfortable.  The struts bear the weight of the vehicle's body, the shock absorbers employ a piston that keeps your tires in contact with the road and controls movement of the vehicle's body.  Springs also absorb impacts from uneven road surfaces. If these components get stuck, either too high or too low, they cause your vehicle to lean.  That's because that side of the vehicle isn't at the height it is designed to be.  A technician will determine where the problem is.  Outside elements such as moisture plus hard knocks to these components can weaken them, even ... read more

The Little Valve that Could (PCV Valve Replacement)

It's easy to get letters like PVC and PCV mixed up.  PVC is a plastic that's used in a lot of things, especially plumbing pipes.  And PCV is a valve that helps your engine burn off excess fumes rather than having them pollute our atmosphere.  PCV stands for positive crankcase ventilation.  When your engine ignites gasoline in the cylinders, some of the gases produced make their way into the crankcase, where oil is held to lubricate the engine.  In earlier days, those gases would be vented out through a hose and go directly into the air.  It was a waste of gasoline (since about three-fourths of the gases were unburned fuel) and a nasty source of pollution. So engineers devised a one-way valve that directed those gases back into the engine's air intake system to be burned again.  After a while, the PCV valve can get clogged up with gummy oil.  Not only does that reduce the recirculation of the gases, but it can also cause pressure in the crankcase ... read more

Steering You Right (Tie Rod End Replacement)

For drivers, S stands for safety.  And there are three other words that start with S that are all equally important: starting, stopping and steering. For your vehicle to be at its safest, all three functions must be in top shape.  Steering is one of those things we take for granted.  After all, you turn the wheel and your vehicle changes direction. But sometimes you might notice your steering is a little off.  Maybe you've noticed you turn your wheel slightly and your vehicle doesn't turn. You may feel a little vibration in the wheel that increases when you go faster.  You may hear a little squeak from the wheels when you steer and you may notice your tires aren't wearing evenly. These are signs that your tie rod ends may be failing. Tie rod ends help connect your vehicle's steering mechanism to the wheels.  They can wear out after you've hit one too many potholes or just from constant use.  They can cause sloppy steering and loose handling, and they ... read more

Oil's Well That Ends Well (Oil Change Grades and Weight)

Changing your oil regularly is one of the most important things you can do to keep your vehicle running well.  And knowing the right type of oil to use is also very important.  Engine oil is classified by weight, but it doesn't refer to how much the oil would weigh if you put it on a scale.  It refers to viscosity, or how easily the oil flows through the engine.  Most engines operate normally at around 210°F/99°C.  The viscosity, or weight, is assigned a number by how well it flows at that temperature.  The lower the number, the more freely it flows.  Most vehicle engines use what's called a multigrade oil which behaves differently in different temperatures. Multigrade oils have a "W" in their viscosity number that you may have seen on a bottle of oil, something like 5W30.  The W stands for winter and shows how freely it flows in colder temperatures. That means a 5W30 oil will behave like a 5 weight oil in lower temperatures (less viscous ... read more

Change Your Wiper Blades Twice Yearly at John's Automotive Care

Because 90% of our driving decisions are based on visual information, unobscured vision is paramount. Which brings us to the topic of today's John's Automotive Care article: wiper blades. While this isn't the most exciting automotive subject, it's important. You wouldn't drive at night in San Diego with your headlights off, but a dirty or streaked vehicle windshield can catch the glare of the sun or on-coming headlights and make it just as difficult to see.Most of us in San Diego replace our wiper blades when they no longer do the job. They are so worn, hard or brittle that they can't clean the windshield. They may even be falling apart. In other words, we deal with our wiper blades from a failure perspective. We address them when they no longer function. The theory, "If it ain't broke, don't fix it," doesn't apply here. Instead, we should think about wipers blades as an important safety system that we should maintain rather than ... read more

Road Trip? Check! (Trip Inspection)

After months of postponing travel far away from home, a lot of us can't wait to hit the road and scream "Road Trip!" again.  But how long has it been since the vehicle you're planning on taking has had a thorough inspection? And is it roadworthy for several days on the highway? Time to schedule a professional trip inspection in our service center.  When it comes to long trips, before you go, make sure you can stop.  We can perform a break inspection.  Our technician will visually inspect your brakes for wear and how much life is left in the brake pads and rotors.  They'll also check your brake lines and fluids for fitness and fill. If it's going to be a long trip, it's important that your engine stays lubricated.  The technician will see when the last time you had an oil change, check the levels and inspect the system for leaks.  If you are close to needing an oil change, it's best to have it done before the trip because no one wants to interrupt a va ... read more
