Frequently driving your car with little fuel can harm your engine over time because the gasoline at the bottom of your tank is usually the dirtiest. When this part is used for fuel, you run a higher risk of dirt reaching your fuel line and engine.

Signs You Need Engine Service

Your engine often gives warning signs before a major failure occurs. Recognizing these symptoms early allows our technicians to perform necessary car engine repair in O'Fallon, potentially saving you from a costly engine replacement later.

Watch for these common indicators of trouble:

  • Strange Noises: You hear knocking, ticking, or squealing sounds coming from under the hood.
  • Warning Lights: The "Check Engine" light or oil pressure warning stays illuminated on your dashboard.
  • Poor Performance: The vehicle feels sluggish, stalls frequently, or has trouble accelerating.

  • Fluid Leaks: You notice oil or coolant puddles forming under your parked vehicle.

Frequently Asked Questions


What Are the Signs I Need a Timing Belt Replacement?

Timing belts are integral to your engine's performance, and signs of wear can include ticking noises coming from the engine, the engine not starting, oil leakage, or misfiring. Ignoring these signs can lead to severe engine damage. 

It is generally recommended to replace your timing belt every 60,000 to 100,000 miles, depending on the type of vehicle you drive and the manufacturer’s guidelines. Our team can assess your car and recommend the best course of action to support its longevity and performance.

How Often Should I Get Engine Service?

Regular engine service is vital for maintaining your vehicle’s health. Many vehicles benefit from a service every 5,000 to 10,000 miles, depending on the model, oil type, and driving conditions. 

During a service, our technicians check vital components, replace oil and filters, and inspect for issues that might require attention. Regular servicing extends your engine's life and enhances your vehicle’s efficiency.

What Happens During a Head Gasket Replacement?

Replacing a head gasket involves removing the top of the engine to access the gasket, inspecting for any warped or cracked parts, and then installing a new gasket. 

This is a complex procedure that our skilled technicians handle with precision, helping ensure your engine is sealed properly to reduce the risk of oil or coolant leaks and maintain consistent performance in O'Fallon's varying weather conditions.

Why Choose Engine Replacement over Repair?

While repairs can resolve many engine issues, certain problems can only be addressed through a complete replacement. If your engine suffers from extensive wear or irreversible damage, replacement may be more cost-effective in the long term. 

We guide our customers through this decision-making process with detailed diagnostics and straightforward advice so you can make the choice that fits your needs and budget.
