Flat tire

Your car or truck owner’s manual shows you how to change a flat tire, assuming a best-case scenario. But the real world includes all kinds of surprises: lug nuts that won’t budge, a wheel that’s rusted to the hub or a spare tire that’s so under-inflated, it’s useless.

Blown fuse

Next time your radio, lights or other electrical feature in your car stops working, chances are a blown fuse is the culprit. Look under “Fuses” in your owner’s manual for help finding your fuse panels. Most manuals have a diagram showing you where each fuse box is. Each fuse panel cover should have a diagram listing each device and the corresponding fuse.

Worn spark plugs

You already know that spark plugs wear out. Well, “burn up” is more like it, because when a spark jumps the gap between two electrodes, it actually burns off (erodes) minute amounts of metal from each one. Over time, the gap grows to the point where the spark can no longer make the jump. That’s when you get misfires, poor gas mileage, lousy acceleration and, ultimately, the dreaded “Check Engine” light. Change your spark plugs yourself to maintain peak performance and high gas mileage. In most cases and with a few of the right tools, it’s a simple job.

Small scratches and chips are unavoidable over time, and it’s important to remove and repair flakes, chips, dents, dings and scratches on your car’s finish before the rust sets in. It takes just a few minutes of your time over a few days. These great auto painting tips and techniques will show you how to touch-up those little eyesores and take years off the look of your car.
