If you've been paying attention, you've noticed that vehicle engines are getting more and more powerful in San Diego. At the same time, they are getting better and better fuel economy. I've gotta tell 'ya, most of that's because of technological advances in transmissions. To get a better understanding of why that is, let's talk bicycles.You've probably seen plenty of cyclists on San Diego roads. Perhaps you ride yourself. Then you know that a cyclist's cadence is the number of times per minute he or she pedals. The ideal pedal speed is the zone where they can most efficiently generate power over a sustained period of time. The experienced CA cyclist uses her gears to keep her pedal speed in the ideal zone whether she's climbing a hill, cruising on a flat stretch or killing a downhill.Think of it this way: if you have a 1-speed bike, you really have to pump hard to get up to speed. Your top speed is limited by how fast as you can pedal. And if you're climbing a steep C ... read more

When asked, most people think they are good at multi-tasking. Scientific studies, however, reveal that only around 2% of the population can truly demonstrate the capacity to effectively multi-task. For the rest of us who are not so biologically wired, no amount of practice can increase our effectiveness at multi-tasking. Turns out, multi-tasking is almost a superpower. Think of fighter pilots: capable of maintaining their orientation in three dimensional space and performing specific and highly complicated functions while accessing life threatening situations and coming up with an appropriate response. Admit it – you can’t do that. Yet when it comes to driving, we seem to think we are very capable of safely operating a motor vehicle with myriad distractions. 77% of young adults feel somewhat confident that they can safely text and drive while 55% claim it’s easy to text and drive. Can they possibly be right? Let’s look at some statistics. Nearly 23% of all accid ... read more

  Your vehicle alternator doesn't get enough credit. Though your battery gets your engine started, after that – it's all about the alternator.  Driving around San Diego is a lot of work for your alternator, and as upgrades such as heated steering wheels, cooled seats, stability control and lane departure warning become more common, it will have to work even harder. Eventually this workhorse just wears out. When it does you have no choice but to order an alternator replacement because your vehicle won't run without one. Come see your friendly and professional service advisor at John's Automotive Care to learn more.

Most auto manufacturers recommend an interval for an air conditioning system inspection. The inspection uncovers leaks, worn hoses and assesses the condition of the other components.Environmental laws in some around San Diego require leaks to be repaired before refrigerant can be added. Also some parts manufacturers require other components to be replaced along with certain failed parts in order to maintain the new part warranty. This is because a given failure may be the result of another worn or damaged part that will, if not replaced, prematurely damage the new component.John's Automotive Care in San Diego is fully equipped to restore your flow of cool air.John's Automotive Care6267 Riverdale StSan Diego, CA 92120619-280-9315http://www.johnsautomotivecare.com  

Your parents probably taught you to have common sense. When it comes to your vehicle, common scents can also come in handy. Different smells may tell you about some conditions in your vehicle that need attention. For example, you know what rotten eggs smell like.  If you smell them around your vehicle, it means sulfur can't be far away. Here's a surprising fact: Gasoline has a little sulfur in it.  There's a device in your exhaust system that's supposed to convert it to something that doesn't pollute the atmosphere. That device is a catalytic converter.  If you are smelling rotten eggs, maybe your catalytic converter is wearing out.  But it could also be a problem with your fuel injectors.  Either way, something's rotten that should be repaired. Ever smell something sweet around your vehicle, maybe a little like pancake syrup? If you sniff out a little sweetness just when your engine is warming up or after you shut off your engine, you might be smelling some co ... read more

Warm weather or cold, San Diego drivers still need to think about their vehicle's air conditioning. Most San Diego people don't service their air conditioning until after it fails. At John's Automotive Care, we can advise you on your vehicle manufacturers preventive maintenance schedules for air conditioning service, just as we do for transmission service, oil changes and so on. Maintaining your air conditioning system means that you always have enough refrigerant to properly do the job. Small leaks in the vehicle's air conditioning system allow the refrigerant to escape and the system can't cool the air as well. We see that a lot at John's Automotive Care in San Diego.The refrigerant also contains oil that lubricates air conditioning components and keeps the seals resilient. Low refrigerant and lubricating oil means that the air conditioning parts will wear out prematurely, and all San Diego vehicle owners know that air conditioning re ... read more

Things we don't expect happen to our vehicles. And let's face, no one really wants to spend money on an unexpected repair. But if you are putting off going to your vehicle repair facility because you're dreading bad news, you might just be putting off some good news. There was one minivan driver who'd had the same van for years and never had a problem with the power sliding doors.  Then one day, the electrical switches in the door pillars stopped working.  The key fob would still open them, but the door switches wouldn't do a thing. Of course, the van driver feared the worst: an electrical problem, a major computer failure, mice chewing up the wires.  So, he put off going into the repair facility for a couple of months.  One day, it was time for his regular oil change and the service advisor asked him if there was anything else going on with the van.  The owner mentioned the door problem but said he didn't want to spend a fortune on it. He waited for his van, a ... read more

The brake rotor, or disc, is attached to your wheel. The brake pads rub on the rotor to slow your car when you are driving in San Diego.Rotors can warp, crack or become misaligned. They can also be damaged by worn out brake pads that scratch grooves into the surface. These conditions result in less contact surface for the brake pads, leaving you with reduced braking power.Over time and miles, rotors can also wear down below safe specifications. It is important for San Diego drivers to know that simply replacing brake pads on a wheel with a bad rotor will not solve the problem. Depending on their condition, rotors may be resurfaced or replaced.Brake noise or a pulsation in the brake pedal are signs of potential brake problems that should be addressed right away. If you have any brake concerns, please have your friendly and professional John's Automotive Care tech perform a thorough inspection.Give us a call.John's Automotive Care6267 Riverdale StSan Diego, CA 9212061 ... read more

If that little brake warning light pops up on your dash, do you know what it means? Well, if you said no, you wouldn't be alone. You know it has something to do with your brakes, but exactly what? You're not sure. One of the reasons is that it could mean a lot of different things. It could be something simple, like you put your parking brake on and forgot to take it off. Easy fix, you're on the road in seconds. Or, it could mean there's something wrong with your anti-lock brake system. That is a pretty complex symphony of speed sensors, computers and wiring, and sometimes things get a little out of whack. You could have a defective sensor or some wiring may have gotten damaged or come loose. A trained technician at John's Automotive Care with special equipment can sort it all out. It's also possible you have low brake fluid. That could be caused by a number of things. One simple reason is that your brake pads have worn down. Replacing them could solve the problem. Another possibility i ... read more

Every day you drive, you're sitting behind the dashboard. But how in the world did it get that name? Back in the days of the horse-drawn carriage, horses would kick up dirt and mud on the driver and passengers, "dashing" debris against the carriage. So those who built carriages began installing a board to protect them. So, dash-board. Dashboard. The dashboard is still there, though changed quite a bit from the early days. Now its main purpose is to house the controls and instruments for your vehicle's systems. Of course, you have the speedometer, tachometer and gas gauge. But there are four warning lights you need to pay attention to on your dashboard and instrument panel. Some of these may even be gauges, depending on your model of vehicle. Regardless, paying attention to them is a good idea if you want your vehicle to keep going as long as possible. Oil pressure—The oil pressure light will come on if your engine doesn't have enough pressure in its system. Low oil pressure means ... read more
