How to Effectively Use a Smoke Machine to Find Vacuum Leaks in Your Vehicle
To use a smoke machine to find vacuum leaks, first, fill the machine with smoke fluid. Connect the machine’s output hose to the intake manifold or air intake system where the leak may be present. Then, turn on the machine and allow it to generate smoke, which will flow through the system. Any leaks present will cause the smoke to escape, revealing the location of the leak. The mechanic can then repair or replace the damaged component.
