How to Spot a Bad Air Conditioning Condenser

Much like a radiator, an air conditioning condenser is used to get rid of heat. But instead of working with the engine cooling system, the condenser helps cool the AC's refrigerant.

Symptoms of a Bad Alternator

Alternator When an alternator fails completely, you’ll know it. In most cases, the charging light will illuminate on the dash, and you may experience one or more of the following symptoms: Engine stalls while driving due to loss of electrical power Dimming of the dashboard and head lights Problems starting the vehicle Repeated need to jump start the vehicle due to dead battery Abnormal noise There are few different ways the alternator can fail: Undercharging: When the alternator is undercharging, the lights may dim or flicker and the battery will become discharged.

How to Tell if Your Spark Plug Wires Are Failing

Spark plug wires, sometimes called ignition cables, aren’t as common as they used to be, but some cars made in the last couple decades still have them. If they go bad, your engine will likely suffer in terms of performance and fuel efficiency.

How to Tell if Your Oil Pump Is Failing

The oil pump delivers a fixed quantity of pressurized oil to the engine, in order to keep it running smoothly. Without the right amount of oil pressure, critical engine parts can begin to rub together, causing extensive — and expensive — damage.

PCV Valve: What it Does, and Symptoms of a Bad One

The positive crankcase ventilation (PCV) valve is an emissions device that keeps pollutants created by your engine from being released into the atmosphere. It also helps keep the engine oil clean and prevents crankcase pressure from building up.

Signs Your Power Steering Pump Is Going Bad

Power steering makes it easier for you to steer your car, especially at low speeds. To do this, the system uses a power steering pump to provide fluid to several other parts.

Signs Your Radiator Is Failing

The radiator is part of the system that keeps your car from overheating. It helps transfer high temperatures from the running engine to the outside air.

Signs Your Steering Gear Is Failing, and What to Do

The steering gear is the heart of the steering system. When you turn the steering wheel, the steering gear transfers that motion to the vehicle’s wheels, multiplying the effort you put in so that you don’t have to do a lot of work to turn the car.
