5.2.1.
For example the maximum pressure in most vehicle turbo systems is
approximately 15psi (1bar) up to 25psi (1.7bar). A vehicle coolant system is
typically rated at 15psi.
5.2.2.
A graduated approach to leakage testing is recommended.
5.3.
tESt MEthOD 1, (REFER tO FIG.2):
5.3.1.
Select the correct air inlet adaptor and plug adaptor (fig.1) by first measuring
the hose diameter. Each adaptor has three diameters to fit different sizes of
hose.
5.3.2.
Set regulator of tester to 5psi to check for large leaks with valve, open
(operating handle inline with the hose axis). and with the air coupling
disconnected.
5.3.3.
Plug the outlet of the system with the appropriate blank end adaptor.
5.3.4.
Connect the inlet adaptor, set at 5psi, to the system inlet.
5.3.5.
Connect the air coupling to check for leaks at the pre-set (5psi). If a leak is
identified audibly or if the pressure gauge pointer falls, it indicates that the
system has a fault resulting in loss of pressure. Repair the leak and retest.
5.3.6.
If no leaks are evident, regulate pressure to 10psi and repeat 5.3.5.
5.3.7.
If no leaks are evident, regulate pressure to a maximum of 15psi or to the
manufacturer's maximum pressure and retest as in 5.3.5.
5.3.8.
If the gauge pointer remains stationary for one minute it will indicate that the
system is in good working order.
5.3.9.
Release the pressure in the system by rotating the ball valve lever to align with hose axis.
5.3.10.
Disconnect the quick coupler, clean and return all items to carry case.
5.4.
tESt MEthOD 2, (REFER tO FIG.2):
5.4.1.
Set up as in test method 1: 5.3.1. to 5.3.5.
5.4.2.
When the system is pressurized, close the ball valve. By closing the ball valve the system is isolated from the constant air supply. The
system can now be tested to ensure it is holding a constant pressure. By monitoring the pressure gauge over a period small leaks can
be detected, showing as a fall in pressure within the system.
6. MAINtENANcE
6.1.
Always keep the plastic adaptors clean and free of oil and grease. Regularly clean with a solvent free cleaner. Ensure components are
dry before storage.
