At Harold's Used Auto Parts Inc in Philadelphia, we believe it’s important for you to know how different systems in your car, truck, or SUV operate. Whether you want to know what to watch out for, or you’re just curious about how things work, we’re here to supply the answers.

Does your sound system not sound quite as good as it used to? Harold's Used Auto Parts Inc in Philadelphia can fix that. While a blown speaker can affect any car, truck, or SUV with at least a radio, modern cars are typically equipped with many more speakers than the vehicles of yesteryear. In a car with only a couple speakers, a blowout is generally fairly obvious; on a newer car, you may have trouble tracking down the source of the problem, but you’re aware the stereo doesn’t sound quite right. A simple speaker replacement may be all you need.

Ride quality is an essential part of your driving experience. At Harold's Used Auto Parts Inc in Philadelphia, we strive to keep your car, truck, or SUV as smooth and comfortable to drive as the day it came off the lot. Your shock absorbers play a huge role in ride quality; here’s what you should know.

At Harold's Used Auto Parts Inc in Philadelphia, we know how annoying a dead battery can be. Here’s some information on the subject, that will hopefully help you understand your battery issues a little better. 

While the Dodge Challenger SRT Demon is certainly no slouch, with a 0-60 time of 2.3 seconds, the fastest production car in the United States may surprise you. It is actually none other than the all-electric, full-size Tesla Model S four-door sedan. The Tesla Model S, as it turns out, can do more than economically deliver your kids to soccer practice; it’s pretty mean on the dragstrip as well. When put into ludicrous Mode, a Tesla Model S is capable of accelerating to 60 mph in a mind-boggling 2.28 seconds, making this family sedan the fastest production car ever built. Regardless of your opinion of electric cars...that’s a pretty impressive feat. 

At Harold's Used Auto Parts Inc in Philadelphia, we know how important climate control is to your driving experience. Not only does a fully functional heat and AC system keep you warm in the winter, and cool in the summer, it is vital to defrosting windows and keeping the air in your car circulating. 

At Harold's Used Auto Parts Inc in Philadelphia, we know how irritating an issue with your car, truck, or SUV can be, even if it doesn’t immediately affect your vehicle’s performance. One such problematic issue, the excessively loud radiator cooling fan, is a common plague many automobile owners will experience.

At Harold's Used Auto Parts Inc in Philadelphia, we know that some of the most elusive issues with any car, truck, or SUV are often caused by the simplest of malfunctions.
