3.3 INSPECTION AND PRESSURE TESTING, AIR INLET SYSTEM
}
When pressure testing the air intake
system, the plugs may spring off if
they are not properly secured.
Check the condition and mounting of the air inlet
channels/pipes of the air intake system.
In case of doubt as to the proper sealing of the air
intake system, which is indicated by the following:
1. loss of power
2. high fuel consumption
3. unusual sounds,
carry out a pressure test to check the air inlet
system for leaks.
1. Remove the pipe between the air filter
housing and the intake port on the suction
side of the turbocharger.
2. Fit the special tools (DAF no. 1329320) and
(DAF no. 1329403) to the suction side of the
intake port and plug the opening.
3. Remove the air inlet hose between the air
cooler and the inlet manifold.
4. Fit the special tool (DAF no. 0694831) onto
the air cooler.
5. Connect a flexible air pipe with reducer valve
to the coupling (A) and charge the system to
approx. 1 bar.
6. Use a soapy solution to check the whole inlet
system for air leaks. Also check whether the
pressure gauge of the reducer valve drops.
