Northtown Auto Service & Tire Center • January 30, 2026

Welcome to the heart of your vehicle—the engine. Keeping your engine in top shape is crucial for ensuring your car runs smoothly, efficiently, and safely. At Northtown Auto Service and Tire Center located in McHenry, IL, we understand the importance of maintaining every component of your engine. That’s why we’re here to share some expert tips on engine services to help you make informed decisions and keep your vehicle performing at its best.

The Importance of Regular Engine Maintenance

Engine maintenance is not just about preventing breakdowns—it’s about ensuring longevity and optimal performance. Regular services help in identifying potential issues before they develop into costly repairs. At Northtown Auto Service and Tire Center, our team recommends following your vehicle's specific service interval schedule to keep your engine running efficiently.

Understanding Engine Oil Changes

One of the simplest yet most vital aspects of engine maintenance is regular oil changes. Engine oil lubricates the moving parts of your engine, reduces friction, and prevents overheating. We suggest checking your vehicle’s manual or consulting with our experts to determine the ideal oil change interval for your car model. Consistent oil changes improve fuel efficiency and extend engine life.

When to Replace Your Engine Air Filter

Your engine air filter plays a critical role in maintaining your car’s performance by preventing dust, debris, and contaminants from entering the engine. Over time, the filter becomes clogged, reducing airflow and negatively impacting engine efficiency. At Northtown Auto Service and Tire Center in McHenry, IL, we recommend inspecting your air filter at each oil change interval and replacing it as needed to ensure optimal engine health.

Spark Plugs – Little Parts, Big Impact

Spark plugs ignite the air/fuel mixture in the engine cylinders, setting off the combustion required for your car to run. Worn spark plugs can lead to misfires, engine hesitation, and reduced fuel economy. To keep your engine firing on all cylinders, have your spark plugs inspected regularly and replaced according to your vehicle’s maintenance schedule.

Cooling System: Your Engine’s Lifeline

The cooling system plays a vital role in dissipating engine heat. Regular checking of coolant levels and ensuring the system is free of leaks are essential steps to prevent overheating. At Northtown Auto Service and Tire Center, we offer comprehensive checks of your vehicle's cooling system, serving McHenry and beyond with expert advice and support.

Check Engine Light – Don’t Ignore It

The check engine light is perhaps one of the most dreaded dashboard signals for many drivers. However, it is a crucial indicator that shouldn't be ignored. It alerts you to potential engine issues that need diagnosis and attention. We recommend visiting us at Northtown to properly diagnose and resolve any underlying problems to prevent further damage.

Fuel System Health

Proper fuel system maintenance ensures efficient engine performance and longevity. This includes regular inspections of fuel filters and injectors to maintain clean fuel lines. Regular service checks at Northtown Auto Service and Tire Center ensure your fuel system is operating smoothly, offering peace of mind on the road.
