Ignition System

The ignition system is one of the most common culprits for engine trouble. While modern cars rely more on computerized components, many ignition elements still need attention during a tune-up. 

• Spark Plugs: These ignite the fuel in your engine, but over time, they wear down from heat and pressure. If the gap between the tip and the electrode gets too big, you’ll either get weak sparks or none at all, which causes engine misfires. That’s when your engine isn’t igniting fuel properly, and trust us, you’ll feel it. When replacing spark plugs, we always recommend using manufacturer-recommended parts for the best performance.
• Ignition Wires: Over time, these wires can wear out, causing the spark plug or ignition coil to lose contact. This can result in a misfire or even cause a cylinder to stop firing completely. We replace them as a set to ensure consistent performance.
• Distributor Cap & Rotor (if applicable): Some older cars have these components, which are vital for distributing the electrical charge to your spark plugs. Just like spark plugs, the metal contacts wear down, leading to random or no firing at all. We recommend replacing both the distributor cap and rotor at the same time for perfect synchronization.

Filters

Filters play a crucial role in keeping contaminants out of your engine and other systems. 

• Air Filters: While your car is running, it’s pulling in air that’s often filled with dust and debris. Over time, a dirty air filter can clog and reduce airflow, leading to poor performance and reduced fuel efficiency. For carbureted engines, it can reduce MPG by up to 14%. In modern fuel-injected engines, it doesn’t often affect performance, but it’s still important to keep your air filter clean.
• Oil Filters: Oil keeps your engine parts lubricated, and a clean oil filter ensures harmful particles don’t cause excess wear. A clogged oil filter can lead to high oil pressure or contaminated oil circulating through the engine, which could lead to serious damage. These filters should be changed regularly during oil changes.
• PCV Valve: Carbon buildup can clog the positive crankcase ventilation (PCV) valve, leading to higher oil consumption and a rough ride. This can also throw off the air-to-fuel ratio.

Belts

Your engine relies on several belts to keep things moving. Over time, they can stretch or crack, especially in hot, dry climates like Louisville. During a tune-up, we inspect your belts for wear and tear and replace any at risk of failing. We pay extra attention to ensure your belts aren’t brittle or cracked due to the local heat.

Fluids

Every fluid in your engine plays an important role, from keeping parts cool to ensuring smooth operation. During a tune-up, we check all your fluids—engine oil, coolant, transmission fluid, and more. Some might need to be topped off, while others are replaced altogether, especially if you’ve recently had other work done.

Battery

Now, here’s a pro tip for all you Louisville locals: our heat can be tough on car batteries. In these instances, batteries typically only last about two years. So, when you’re buying a new one, opt for a battery with a 3-5 year warranty. Trust us, it’s worth the extra cost upfront to avoid getting stranded with a dead battery.
