Vehicle Parts Often Changed during a Tune Up

Your vehicle needs a tune up on a regular basis to keep it running properly. This simple routine checkup at your auto repair shop also helps you avoid costlier problems down the road. But what parts typically need replacing during a tune-up?

Below, we look at these parts and why it is good to replace them.

Spark Plugs

Over time, the spark plugs’ electrodes wear down. Being worn increases the distance voltage must travel to create the spark. When the ignition system must produce increased voltage, you risk the spark plugs misfiring and your vehicle not starting. Dust and other deposits can also build up on the spark plugs, interfering with the voltage, too.

When replacing these parts, your auto mechanic can install long-life spark plugs. These last longer, even up to 100,000 miles for typical driving conditions. Although they cost more up front due to being made with gold-palladium alloy or platinum, they can save you time and money in the long run.

Rotor Cap or Distributor Cap

The rotor cap or distributor cap passes voltage from the ignition coils to the engine’s cylinders. This ignites the fuel. A worn cap no longer correctly passes the voltage as it should, causing your engine to not start. You need to have this part replaced at every tune up, since it wears down quickly.

Filters and Valves

Your vehicle has multiple filters and valves. These require replacement from time-to-time during a tune up. Your auto mechanic should pay attention to the fuel filter, air filter and breather filter. He or she should also check the PCV valve, wires attached to the spark plugs, belts, hoses and other easily worn down parts.

Oxygen Sensors

The oxygen sensors in your vehicle play a major role in your engine’s fuel control feedback loop. They measure your exhaust’s unburned oxygen levels and send this information to your car’s computer. The computer uses the data to adjust the fuel mix to manage vehicle emissions.

When your car’s oxygen sensor shorts out, emission levels rise. This triggers the check engine light to turn on in many cases. But sometimes this warning system fails and you do not know the part has failed.

Oxygen sensors can fail for a number of reasons. For example, debris entering the exhaust can obstruct the sensor. Or this part just wears out over time. A tune up is the perfect time for your mechanic to check the sensors for proper functioning and replace them when needed.
