Leak Test:
The purpose of a leak test is to verify if a system is leaking and after repairing the vehicle, confirm
that the leak has been fixed. The Cool Smoke HP has two different leak tests: Leak Size and
Pressure Decay.
1. Leak Size Test
The Cool Smoke HP has advanced electronics that are capable of determining the size of a
leak that is greater than 0.015” ( 0.4mm).
2. Set the test pressure by using the scroll
buttons ( ) to adjust pressure.
The test pressure should be the same or
less than the operating pressure of the
system being tested.
3. Follow on screen instructions and press
the ( ) button to start pressurizing
the system.
4. The machine will fill the system with
pressurized smoke until the set pressure
is reached.
5. Results - When the output
pressure stabilizes at the
set pressure, the leak size
results page will display
the leak size and resulting
flow rate from the test.
