A technician was telling us the other day that he was servicing an engine and spotted something he'd never seen before: A collection of dry dog food siting on a horizontal metal ledge near the base of the engine. It was neatly stashed and was in a spot where the food pellets couldn't have simply fallen down in there. Even though it's the first time he'd seen dog food in an engine, he immediately knew what was going on. Critters like mice or chipmunks had found the dog food somewhere nearby and had used the engine as a nice storage unit. Mice, squirrels, chipmunks—you name it—like the heat of the engine. And they'll use that to store up supplies of food for use in cold weather when outside food supplies are scarce. The problem is they'll also chew on engine components while they're there. And they can do a lot of damage if they start gnawing on the wires. Depending on how much of your electrical system needs to be replaced, repairs can mou ... read more

Sometimes the movie is better than the book, sometimes it's the other way around. But when it comes to your vehicle, the best book of all is the owner's manual. The plot is simple: Owner wants long life and dependable performance from the vehicle, manual has the way to achieve that long life and dependable performance. And yet, it's amazing that some people will own a vehicle for years and never even crack this book. They'll only read it when they absolutely have to, for things like finding out how to change the clock. Ok, so you're probably not going to rush right over to your glove box and start reading the owner's manual cover to cover. We know that. But just think of what you can get out of it. Consider this. Those who wrote or helped write this book include the engineers who designed it and the people who tested and refined it. They know more about your vehicle than anyone, period. They know how long a part is likely to last and what ... read more

They say your vehicle has one, but you've never seen it. And you might not even know it if you stumbled on it accidentally. We're talking about the jack, that tool that allows you to lift one corner of the vehicle up so someone can change a flat tire. So you say you'd never try to change a flat anyway, so you don't care where it is. But one day, you may find yourself in a spot where you're stranded with no cell service and you'll need to at least know the basics of what to do. Well, here's the ironic part. Many of today's vehicles don't even have jacks and spares! Recently, manufacturers have been saving weight by supplying another solution for a flat tire, such as an inflator kit that has a tire sealant in it, or a small compressor. If your vehicle has one of those, it's a good idea to get to know how to use it before you need to use it. Hopefully you'll be able to call roadside assistance and they can take care of things, but circumstances may prev ... read more

When it comes to your vehicle, driving it too much can cause some issues. But what about not driving a vehicle enough? That has consequences as well. Here are a few things that can happen if a vehicle isn't driven enough. When the engine doesn't operate, the oil isn't lubricating. That means some mechanisms that need periodic lubrication aren't getting it. And oil that sits around breaks down over time. In fact, some experts say you should change oil more often if your vehicle sits in the driveway than if you drive it regularly. You've heard that expression, "Take it on the highway and blow out the engine.” Well, carbon buildup used to be a problem in older vehicles. But the real culprit these days is moisture that builds up from combustion if your vehicle never gets hot enough to burn it off. That water vapor can mix with oil and cause sludge to form. There are many vehicle systems (battery, exhaust system, engine seals, etc.) that benefit fro ... read more

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. That is why so many CA ] owners rely on the advice of their friendly and knowledgeable John's Automotive Care service advisor to not only get the correct family of fluids, but to suggest the formulation that is best for their vehicle and their driving habits in the San Diego area.Let's start with engine oil. 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
