Your alternator is a central component on any engine.

Has your brake master cylinder gone bad? How would you know? What even is it? Harold's Used Auto Parts Inc in Philadelphia, PA has the answers.

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 given out on you.

Are your fleet vehicles equipped with four-wheel or all-wheel drive?

Failed engine mounts are an irritating issue to live with causing your car or truck to vibrate and you don't know why. At Harold's Used Auto Parts Inc in Philadelphia, PA, we can help, no matter what type of car, truck, or SUV you drive and it is an easy issue to detect on a test drive.

There are a few indicators your engine mounts need to be replaced. For one, you can do a visual inspection, if they’re accessible enough - if they looked cracked, smashed, or dry-rotted, it’s probably time for new ones. If the engine visibly shakes while it’s running, engine mounts are also likely the culprit. However, if you are like most drivers you simply get in and drive on down the road until something is different or a light comes on! Then you call our shop for help!

When you are having trouble with your car or truck starting and you open the hood up to take a peek to see this....you'll see what an overly corroded battery looks like. This happens naturally over time on vehicle battery terminals. If you are like 99% of normal Philadelphia drivers, you don't check your oil or your battery so you don't keep an eye on the amount of corrosion that's building up on your car or truck battery. Here at Harold's Used Auto Parts Inc, we do and there are solvents that we can use here in the shop during a battery maintenance service that will help slow the corrosion process but nothing that can prevent it 100%. Way before it gets to this point, we will be suggesting you consider replacing the battery.

Our fleet truck customers do not need to spend valuable time in the shop with transmission issues due that could have been avoided by servicing their fleet vehicles based on their owner's manual recommendations! Especially if it is simply changing a clogged filter, changing fluids or clutch issues! Our transmission technicians here at Harold's Used Auto Parts Inc in Philadelphia believe that service = saving high repair bills! Therefore, we believe in a proactive approach!
