What Does an Engine Inspection Entail?

engine inspection

A vehicle engine inspection can detect potential problems before they occur or current issues before they turn into major expenses. The entire system is checked and the technician will make recommendations based on the findings.

Basic inspection for an engine tune-up

When you take your vehicle in for a tune-up, the technician will inspect the following components:

  • Spark plugs and wires to check for wear and proper performance.
  • All of the components of the engine, looking for dirt, grime or leaking fluids.
  • Ignition timing.
  • PCV valve.
  • Idle speed.
  • Belts and hoses.

The mechanic will also:

  • Open up the case and inspect the air filter.
  • Measure oil and coolant levels.
  • Conduct an emissions inspection.

An in-depth inspection

When you consider purchasing a used vehicle or if there are unresolved issues that a basic inspection doesn’t find, you may need a more detailed engine inspection. Many of these components are inspected before a certified pre-owned vehicle is put on the lot for sale, making it a good procedure for your own purchase.

  • Check for sludge in the oil.
  • Listen for the engine cold start and idle to make sure no abnormal sounds are present.
  • Make sure engine reaches normal operating temperature.
  • Check to make sure vehicle is drivable during warm-up and at regular temperature.
  • Check that the engine fans operates properly.
  • Listen for vibration in engine.
  • Inspect engine mounts for damage.

When you have your engine inspected by a professional, you can feel confident that your vehicle is ready to drive.
