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

Here is a questions for San Diego drivers: What is a cabin air filter?Is it: A filter for a house in the middle of the woods? A fresh, piney scent? A filter for the passenger compartment of your car? Clever you, it's 3.A cabin air filter cleans the outside air before it comes into the passenger compartment. It filters out dust, pollen, spores, bacteria, pollutants, sparrows, exhaust gas and odors.These high tech filters can block particles larger than 3 microns. By contrast, a grain of sand is about 200 microns.Now not all vehicles in the San Diego area have cabin filters. They are fairly new on the scene in CA. About 40 percent of new vehicles come with cabin air filters, but the number is growing every year.Cabin air filters can make for a very nice driving environment for San Diego. Your car can be a haven during CA allergy season with very little dust and pollen getting into the cabin. However, like all filters, your cabin air filter eventually ge ... read more

A generation ago, San Diego drivers seemed to be more inclined to keep their vehicle's preventive maintenance on schedule. One reason for this may be that vehicles back then were a lot less reliable than they are today. Taking your vehicle in to your San Diego shop every year or two for repairs seemed to be a good reminder to keep the oil changed.For example, almost everyone in San Diego used to take their vehicles in for regular tune-ups. Vehicles had mechanical ignition systems, which meant ignition points, spark plugs and coils had to be replaced and the timing adjusted every few years. As long as the vehicle was in for a tune-up at John's Automotive Care, the vehicle was inspected and you took care of any needed repairs at the same time.Today's engines have electronic ignition systems and engine control computers. Spark plugs can last for up to 100,000 miles/160,000 km. Vehicle reliability has vastly improved in the last few decades, and surveys report f ... read more

If your vehicle had something in its design or production that the manufacturer had figured out had an unanticipated problem, you'd want to know about it. And you'd want it fixed. There is something that can help drivers with just such a scenario. It's called a Technical Service Bulletin, or TSB. Here's what a TSB is. Vehicle design and manufacturing is a very complex process. Aftrer every vehicle is introduced, the more units there are on the road, the more likely weaknesses in parts or design will start to show up. Automakers gather data on the issues and how best to fix them. Then they send out TSBs (usually in the first year of the new model) so technicians will know to look for those problems and what to do about them. There may be more than one cause of a problem with a vehicle so there may be more than one TSB for an issue. A TSB can be issued for anything from failing water pumps to strange noises to smelly headliners. A TSB and a recall aren't the same thing. A recall is issue ... read more

Many San Diego drivers have been hearing about technological advances in power steering, specifically electric power steering. Some very high-end cars have been featuring electric power steering. Power steering fluid has the necessary hydraulic properties and the ability to lubricate the internal parts. The power steering fluid also protects vehicle components from rust and corrosion.San Diego car owners should be aware that vehicle manufacturers recommend that the fluid be replaced on schedule. At John's Automotive Care, the old fluid is drained and the system cleaned thoroughly. Fresh fluid is then installed.Unfortunately, many San Diego drivers don't realize how important it is to service their power steering, and some may not even know that it's necessary in the first place. A neglected power steering system can develop leaks that will shorten the life of the pump.San Diego drivers shoul ... read more

CA service centers have a menu board that lists the services they provide. Some San Diego drivers may not be familiar with all of the items on the board so here is a quick description of some of the typical services that might be listed.John's Automotive Care fuel system cleaning: Over time, the vehicle fuel system gets gum and varnish built up. A fuel system cleaning gets rid of that and cleans out the fuel injectors. Saves gas, by the way.John's Automotive Care headlamp replacement: Halogen and standard headlamps gradually fade. It's usually good to change them every year or so.John's Automotive Care inspections: San Diego drivers get inspections for many reasons. Maybe they're going on a trip or just want to make sure their vehicle's ready for a CA summer or winter. Maybe they just bought a used vehicle and want to give it the once over. An inspection may reveal some things that are broken or are get ... read more

San Diego residents know that engines need to burn fuel to operate. Fuel is pumped from your fuel tank to your vehicle engine where it is squirted—or injected—into your engine's cylinders. This is the function of the fuel injectors.There are two ways to inject fuel into an engine. Fuel needs air to burn, so in the first method, fuel is injected into a port and allowed to mix with air—before it is drawn into the cylinders. In the second method, fuel is injected directly into the cylinders and mixes with air after it enters the vehicle engine.Direct injection engines burn fuel more efficiently than conventional vehicle engines. Some models can deliver the power of a V8 with the economy of a V6.For example, in one family of engines, the conventional version (a V6) delivers about 250 horsepower. The direct injection version delivers over 300 horsepower and gets about the same gas mileage. The turbocharged version delivers 350 horsepower ... read more

When your vehicle has a problem or just needs some routine service, you might get a little nervous. Your vehicle's so important to your life in San Diego, you need to get back on the road as soon as possible – with the problem fixed right the first time.If you've ever checked into some of the technician training John's Automotive Care professionals receive, you may be surprised at how much specialized knowledge and skill goes into diagnosing and repairing a modern car. For example: Today there are four cylinder engines that generate more power than the 1980s-era V-8's. I mean a new V-6 Toyota Camry could beat Sonny Crocket's Ferrari in a race to 60 mph/100 kph. Our engines are more and more powerful and at the same time their fuel economy keeps inching up – even with steep San Diego gas prices. They are also amazingly reliable: Kudos to the automotive engineers. But the advances come at the price of simplicity. The moder ... read more

San Diego area drivers love their vehicles. And one of the most enjoyable things about them is taking a road trip. Freedom from daily schedules, new sights and the open road – it's great! But there's nothing like vehicle trouble to bring the fun to a grinding halt.

Now San Diego drivers can't always avoid problems, but you can take steps to reduce the probability of getting sidelined on your trip. The first step is to look at your trip plan from your vehicle's perspective. What kind of roads will you be traveling – winding CA byways? Purple mountain majesties or fruited plains? What weather conditions are you likely to encounter? How far will you travel each day? How much weight will you be hauling – passengers and luggage? Pulling a trailer, roof top carrier or ATVs? Will it be dusty? Prepared with answers to these questions, you can schedule a trip inspection at John's Automotive Care in San Diego to help you

If you've ever heard a squealing sound under your vehicle hood, chances are it was your serpentine belt. More importantly, the belt powers the alternator. The alternator creates electricity that's used by your vehicle's electrical systems and also charges the battery. Without the alternator, the battery will go dead after a short distance.The serpentine belt may also run the pumps for both the power steering (some are electric) and power brakes (some use vacuum boost).And, on most vehicles, the serpentine belt powers the water pump. The water pump circulates coolant through the engine to keep it within optimal operating temperatures. On some San Diego vehicles, the water pump is powered by the timing belt instead of the serpentine belt.When they understand what it does, San Diego drivers realize that if it breaks, it affects a lot of systems. That's why vehicle manufacturers outline recommended replacement guidelines in the owner’s manuals. If thi ... read more
