Let's face it.  New vehicles are expensive, so finding a good used one can save drivers a lot of money.  It's tempting to look through ads, find a private seller who has what you're looking for and pay a price you think is a great deal.  But when you go over to look at a used car, do you really know what to look for to uncover potential problems with it? The answer is probably no.  Used cars can look great on the outside, maybe even have lustrous paint and a super clean interior. But is it possible that vehicle's been in an accident? Does it have electrical problems you can't detect easily? Is any fluid leaking that you don't know about? Think about it.  You are about to spend thousands of dollars for a complex machine and you're considering judging its condition without much expertise.  That's why it makes sense to have a qualified technician inspect any used vehicle you're considering buying. Many vehicle repair facilities will do it for around ... read more

The automotive professionals at John's Automotive Care would like to give San Diego drivers an update on some of the things happening in automotive fluids. You know, vehicles are becoming more sophisticated every day.  Fluids such as, oil, coolant and transmission fluid are becoming more specialized at about the same pace.The San Diego do-it-yourselfer has to be pretty careful so that they do not actually harm their vehicle with the wrong type of fluid.

San Diego drivers who have been paying attention will have noticed a number of new oil weights on the CA scene in the last several years. Modern ... read more

You may be driving along and find that suddenly your radio stops working.  There are no numbers on the display.  Then when you get home, you notice the garage door opener doesn't do a thing when you press the button. Hmm, this was working just fine this morning.  Are the two problems somehow related?   No, your vehicle doesn't need an exorcism. This has all the signs of an electrical issue, and when you experience symptoms like those, you've probably blown a fuse.  Most vehicles have fuses just like most houses have circuit breakers (some houses still have fuses). They cut the power when it reaches a pre-determined threshold that could cause major damage if it was allowed to continue.  You might say fuses take one for the team. Most modern automotive fuses are plastic with a thin strip of metal in them designed to melt when a calibrated amount of power passes through.  The philosophy is it's better for an inexpensive fuse to be destroyed than your sou ... read more

Today's vehicles have some pretty amazing technology in them, including a computerized braking system we all pretty much take for granted these days.  Antilock brake systems (ABS) have been around for years but they help drivers stop in much shorter distances reliably than ever before.  When you see your ABS warning light come on, it's important to find out what's causing the problem. It's a safety issue. Often the problem when the ABS light comes on is a faulty wheel speed sensor.  (In some cases the traction control light will also come on, perhaps because of a non-working wheel speed sensor.) Your vehicle uses the speed sensors to measure the rotational speed at each wheel. That sensor sends the speed data to a computer that can then adjust braking power and prevent your wheels from locking up.  If any of the wheel speed sensors isn't working right, the ABS warning light will go on and the vehicle's computer will turn off the antilock brake system.  You'll s ... read more

Every one of us has a little procrastinator inside us. Some put off getting our teeth cleaned. Others put off answering our emails. Yet others put off calling friends and family (sorry, Uncle Joe). And there are those of us who put off getting our vehicle's service done, whether it's a repair or regular maintenance. You may make the excuse that you don't have time, it can wait until tomorrow, you have other things to do. Well, there are some things you should NEVER put off when it comes to your vehicle because that procrastination could have dire consequences down the road. The biggest one is changing your oil. Yes, it's one of those things you may hear somebody nag you about, but changing your vehicle's oil regularly is probably the one thing that will do the most to keep things running smoothly… and well. It's the lubricant that keeps metal engine parts from wearing out. Oil doesn't last forever and it gets dirty, so you have to swap it out for fresh every so often. How often ... read more

If someone told you that your vehicle could have the same power but with a smaller engine, wouldn't that sound like great idea? Just think, a smaller engine would save you money at the gas station and you'd still get the same horsepower. The technology to do just that has been around for a long time. It's called a turbocharger. Race cars and other performance vehicles have been using turbochargers for years. It gives them a power boost without the need of a bigger engine, saving them fuel and pit stops. Automakers have offered turbo gasoline and diesel engines for years, but there were problems with durability. Plus drivers had to make some driving adjustments with the way turbos delivered power. Newer turbos, though, have been vastly improved, and manufacturers are including them in more models. For example, Jeep offers its 2019 Cherokee with a choice of two engines that each make about 270 horsepower. One is a 4-cylinder turbocharged engine and the other is a 6-cylinder conventional ... read more

When San Diego drivers need to replace tires, they need to know how many they should get and on which axle they should be placed. Replacing a damaged tire may leave you with three others with significant wear, which could affect your traction control, stability control and anti-lock brake systems.If you can’t afford to replace all four tires at once, you should at least replace two on the same axle. New tires should always be put on the rear axle for stability in slippery conditions. Your friendly and professional John's Automotive Care tire professional can help you know when your worn tires should be replaced, if you can have a damaged tire repaired as well as selecting the right tires for your needs.Give us a call.John's Automotive Care6267 Riverdale StSan Diego, CA 92120619-280-9315http://www.johnsautomotivecare.com

In the hot weather, seeing steam coming from the engine compartment is something we all dread.  No one wants that to happen to them. But if you know the signs of overheating and how to deal with it, you may be able to reduce the risk of damage to your vehicle, maybe even prevent getting stranded on the road. Besides the steam coming out of the engine compartment, here are a few signs of overheating.  Your vehicle has a heat gauge that may have a needle that can go into a red zone or up to the "H" (for High) position.  You may smell odors, perhaps a burning (could be hot oil) or a sweet smell (engine coolant leaking).  When you encounter any of those signs, you know you have to do something to keep the engine as cool as possible to avoid potentially catastrophic damage.  Turn off the air conditioning and turn up the heat.  While that last part may sound odd, it helps draw heat out of the engine.  If you can do it safely, pull off the road to a spot awa ... read more

If you saw a dollar bill on the ground, you'd pick it up, right? Well, whether you find that dollar on the ground or in savings at the gas pump, money is money, and here are some ways to hold on to more of it. Slowing down is the easiest way to save fuel, especially for every speed increase over 50 mph/80 k/hr.  Tone down the speed, turn up the cash savings.  Drive smoothly (not like a race car driver) and you'll also save money in fuel.  Aggressive, fast-start, jerky-stop habits are just pulling the bucks out of your wallet about a third more than if you drove just a little more gently.  Oh, and cruise control can help with that smooth, steady speed, so use it on the highway. Bonus! Are you hauling around a set of dumbbells or a box of books? That extra weight is costing you dough.  Store them somewhere else.  When's the last time you checked to see your tires were inflated properly? That's another money saver and makes your vehicle safer. An idle thought ... read more

When the weather turns cold, it's nice to crank up the furnace and enjoy the heat. But if your home's furnace doesn't work, it's not too comfortable. Same goes with your vehicle. When the heater's not working, things can get miserable. It could also signal some major problems, which we'll discuss later. A vehicle's heating system is fairly complicated. It's made up of several parts, including a blower motor/fan, a heater core and some mechanical and electrical components. In basic terms, a vehicle's engine warms up coolant which is then sent to the heater core (which is kind of like a small radiator) behind the dash. That blower motor sends cold air through the heater core which heats up the air. Voila! Heat. Diagnosing problems in this system takes a trained mechanic because of the different possible issues. Your heater core may need replacing; they are sometimes in tight spots and may be difficult to work on. Another possible problem could be a defective thermostat, which regulates h ... read more
