Activate pump and pressurize engine cooling sys-
tem to 34 kPa (5 PSI).
Wait 3 minutes and check if pressure drops; if so,
verify all testing components.
– If kit components are not leaking and pressure
drops, verify all external jointed surfaces and
temperature sensors. If none of these compo-
nents are leaking, there is an internal leak and it
can be detected with Bottom End and Top End
testing.
Bottom End and Top End
NOTE:
Use the intake and exhaust plates included
in the Supplementary Engine Leak Test Kit (P/N
295 500 780).
Carburetor-Equipped Models
Remove the carburators and gaskets. Make sure
the surface of the intake manifold are clean.
Install the intake plates with fasteners from the kit
and tighten adequately.
NOTE:
Use the intake and exhaust plates included
in the Supplementary Engine Leak Test Kit (P/N
295 500 780).
DI Models
Remove throttle bodies on
DI models
.
Install intake manifold plugs (P/N
529 035 708)
.
All Models
Remove the RAVE valves and gaskets.
Install the RAVE valve plate with fasteners from
the kit and tighten adequately.
NOTE:
The boot (
carburetor-equipped engines
)
and O-ring can be checked for leakage with the
valve in place. Simply remove the cover to expose
the parts.
Make sure the spark plugs (and the air/fuel rail on
DI engines
) are installed and tightened.
Block pulse hose (
carburetor-equipped engines
)
using a hose pincher.
Install pump to the exhaust plate fitting.

1. Exhaust plate
2. Rave valve plates
3. Intake plates
Activate pump and pressurize engine to 34 kPa
(5 PSI).
CAUTION:
Do not exceed this pressure.
Wait 3 minutes and check if pressure drops; if so,
verify all testing components.
If kit components are not leaking, verify engine
jointed surfaces as per following areas:
– spark plugs
– direct injector sealing (
DI engines
)
– cylinder head gasket
– cylinder base gasket
– crankcase halves
– intake flanges
– engine plugs
– exhaust manifold.
