Smoke Test for Air or Boost Leaks? Engine Diagnostic in Newtownabbey

If your car is losing power, smoking, making unusual noises, or showing engine warning lights, an air or boost leak could be the cause. At 1Stop Motor Shop in Mallusk, Newtownabbey, we use smoke testing diagnostics to help drivers across Glengormley, Carnmoney and Belfast find hidden leaks quickly and accurately.

What Is a Smoke Test on a Car?

A smoke test is a diagnostic procedure used to find leaks in the engine’s intake or boost system.

Smoke is introduced into the system to reveal leaks that may be difficult to see normally.

This helps identify:

• Air intake leaks
• Boost pipe leaks
• Vacuum leaks
• Cracked hoses or seals

It is one of the fastest and most accurate ways to diagnose hidden engine leaks.
