On-Site Auto Tune-Up in Arlington, TX

Ignition System

The ignition system is critical and can lead to various issues if not properly maintained. Even in modern vehicles with computerized systems, some components might not be included in your vehicle’s tune-up checklist.

Spark Plugs

Spark plugs play a crucial role in igniting the fuel in your engine. They feature a small metal tip that can wear down over time due to heat and pressure. If the gap between the electrodes becomes too large, the spark plug may misfire, preventing fuel from igniting in the cylinder. When replacing spark plugs, it’s best to use the original equipment recommended by your manufacturer.

Ignition Wires

Over time, ignition wires can deteriorate, leading to a poor connection with the spark plugs or ignition coil. This can prevent a cylinder from firing entirely. It’s advisable to replace these wires in sets to ensure uniformity. The wires are arranged in a specific configuration to match the cylinder rotation; crossing them can cause the engine to run roughly, as the timing will be off.

Distributor Cap and Rotor (if applicable)

The distributor cap houses a rotating arm with a metal tip that transfers the spark to the spark plugs. With time, these contacts can wear down, resulting in inconsistent or no firing. During a tune-up, we recommend replacing both the cap and rotor simultaneously for optimal performance.

Filters

Your car is equipped with several filters that protect the engine and the vehicle’s interior from contaminants. Clogged filters can significantly affect engine performance.

Air Filters

As your car operates, air continuously flows into the engine. Over time, the air filter can become clogged with dust and debris. A dirty air filter can reduce fuel efficiency by up to 14% in carbureted engines and can impact performance, even in fuel-injected models.

Oil Filter

Oil filters are essential for lubricating your engine. A clean oil filter prevents particles from causing wear on engine components. Contaminants can circulate if the filter becomes clogged, leading to potential issues like high oil pressure. We recommend changing the oil filter at every oil change.

PCV Valve

Over time, the positive crankcase ventilation (PCV) valve can become blocked with carbon, which may lead to excessive oil consumption and an imbalanced air-to-fuel ratio.

Belts

The engine has various belts, each serving a unique purpose. Over time, belts can stretch or wear out, and many are replaced during a comprehensive engine tune-up. We also check for cracks or brittleness in Arlington’s heat to ensure longevity.

Fluids

During a tune-up, we inspect all fluid levels and either change or top them off as needed. Many fluids require replacement when specific components are serviced.

Battery

For all Arlington drivers, consider this: the extreme heat can significantly shorten battery life, often to just two years. When purchasing a new battery, opt for one with a 3 to 5-year warranty. This way, when it eventually fails (and it will), you can easily swap it out for a new one.
