The interior of your car can be difficult to maintain; between you, your kids, and anyone else who gets a ride from you, wear and tear on the interior of your vehicle is constant.

Your vehicle's belts and hoses are essential to the cooling, air conditioning and charging systems, and the engine. Don’t take these routine replacement intervals for granted because they can break down and leave you stranded.

What is the purpose and importance of your belts and hoses? The timing belt keeps the crankshaft and camshaft mechanically synchronized to maintain engine timing. Whether serpentine, V-belt, or fan belt (the belts on the outside of the engine), they all transmit power from the front of the engine to accessories that need to be driven, such as the air conditioning, the charging system, and fans. Radiator and heater hoses carry coolant to and from the engine, radiator, and heater core.

Part of maintaining your vehicle is keeping its safety devices in good working order, especially when there are kids in the car. 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 is here when they do; here are some things to watch out for.
