It isn’t easy keeping your fleet or commercial trucks up and running. At Harold's Used Auto Parts Inc in Philadelphia, PA, we’re here to help. Fleet and commercial vehicles log a lot of miles, and a lot of hours - as a result, even the most reliable components need to be serviced occasionally. On an ordinary diesel, an injection pump may last the entire life of the engine itself. On vehicles that work harder than anything else on the road, this isn’t always the case.

Antifreeze is a fluid that’s just as important as oil to the engine in your car, truck, or SUV. You probably already know it’s essential to keeping your engine cool - but it’s important for more than one reason, and does require maintenance besides keeping it full. From Harold's Used Auto Parts Inc in Philadelphia, PA, here’s what you need to know about antifreeze.

Push Start Button on Vehicle

When a vehicle has trouble starting, many people initially blame the starter. What is the starter, and how do you know if yours has called it quits? At Harold's Used Auto Parts Inc in Philadelphia, PA, we want to keep you informed, and telling you what to look for will prevent further damage when issues arise. The starter is essentially just an electric motor; a gear at the end of that electric motor engages the flywheel, which turns the engine over, allowing it to start. How do you know if yours is failing?

Your brake master cylinder is an integral part of your brake system. When one fails, some odd symptoms may arise, and it may be difficult to diagnose. Here’s some information to help you decide if yours has gone bad. At Harold's Used Auto Parts Inc in Philadelphia, PA we want you to know what to look out for so that you can be safely on the road.

headlight of car

Foggy headlights are a problem that has arisen in the past couple of decades, as we have moved away from glass sealed beam bulbs and into an era of plastic lenses with bulbs inside. While modern headlights are superior to the sealed beam headlights of years ago, they do tend to fog up after years of use. It’s a good trade for far better illumination and easier replacement, but an issue nonetheless. Hours and hours of heat, sunlight, and age eventually cause them to cloud up, which can reduce visibility at night in addition to worsening the appearance of your car, truck, or SUV. From Harold's Used Auto Parts Inc in Philadelphia, PA, here are some tips on taking care of your foggy or cloudy headlight issue.
