3 Vacuum reservoir
A vacuum reservoir is included in the vacuum supply line between the intake manifold and the SAI vacuum solenoid
valve. The vacuum reservoir contains a one-way valve, to stop depression leaking back towards the intake manifold
side. The reservoir holds a constant vacuum so that the SAI control valves open instantaneously as soon as the SAI
solenoid valve is energised.
The vacuum reservoir is a plastic canister construction located on a bracket at the LH side of the engine compartment
on vehicles up to 2003 model year and on the RH side of the engine compartment, near the bulkhead, on vehicles
from 2003 model year. It is important to ensure the reservoir is fitted in the correct orientation, and the correct vacuum
hoses are attached to their corresponding ports. The one-way valve end of the vacuum reservoir (cap end, to inlet
manifold) is fitted towards the rear of the vehicle.
A small bore nylon hose is used to connect the one-way valve end of the vacuum reservoir to a port on the RH side
of the inlet manifold. A further hose connects between the other port on the vacuum reservoir and a port on the front
of the SAI vacuum solenoid valve.
