Part of maintaining your vehicle is keeping its safety devices in good working order, especially when there are kids in the vehicle. Seat belts, window locks, and airbag sensors work together to keep children safe in an automobile. Though safety components are generally very reliable, they do occasionally fail. Harold's Used Auto Parts Inc in Philadelphia, PA is here when they do; here are some things to watch out for.

Dirty Hands Working on a diesel truck engine

Keeping your fuel system maintained will prevent premature parts failure and poor running conditions.

While your system and components should typically be serviced by a professional technician, there are some things you can be conscious of that will go a long way toward keeping your engine in good shape.

flood with a car in it.

Unless you are confident in your abilities as an automotive mechanic, there is really only one rule when purchasing a flood-damaged vehicle: don’t do it. Unfortunately, sometimes sellers aren’t particularly straight-forward with their used cars. Many will try to hide the fact that it’s been damaged by floodwaters at all or try to convince potential buyers that the car is in fact fine. “It has gone months with no issues” or “technically it is flood-damaged but” are two red flags, and while it isn’t impossible for a flood car to be fine, it’s altogether a good idea to stay away.

At Harold's Used Auto Parts Inc in Philadelphia, we understand all too well the importance of changing your oil regularly.

Every year, more and more trucks come equipped with turbochargers. What was once a novelty or a performance option has become increasingly common as stock equipment. What are they for, and how do they work? Harold's Used Auto Parts Inc in Philadelphia, PA is here to help.

fleet trucks

It’s easier than ever to keep your fleet running smoothly for thousands of miles. If a vehicle has less than 50,000 miles on it today, chances are it still has 75 percent of its driving life ahead of it. That’s good news if you’re a company managing a fleet of vehicles. It wasn’t that long ago that hitting the 100,000-mile mark on the odometer was a major milestone. Today, vehicles are built to last. With the proper maintenance and attention, there’s no reason you shouldn’t expect to see that 50,000-mile reading on the odometer one day roll right past 200,000 and keep ongoing. Here at Harold's Used Auto Parts Inc, we're going to give you some tips on how to make that happen!
