TESTING PROCEDURE
Engine Cooling System
Remove the tuned pipe.
Remove the exhaust manifold gasket and ensure
the surface is clean.
Disconnect engine cooling hoses.
Install the appropriate exhaust manifold plate (P/N
296 000 027), included in the Supplementary En-
gine Leak Test Kit (P/N 295 500 780). Tighten plate
using fasteners provided in the kit.
Install a hose pincher on engine drain hose.
Use hoses provided in the kit and install them on
the engine.
Install pump using reducer and appropriate tube(s)
as necessary.
NOTE: Water is not required for testing.
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, tem-
perature sensor and the O-ring between the
spark plug area and the engine cylinder head
cover. If none of these components are leaking,
there is an internal leak and it can be detected
with Bottom End and Top End testing.
Bottom End and Top End
Remove the carburetor(s) and gasket(s). Make
sure the surface of the exhaust manifold is clean.
Install the intake plates (P/N 296 000 025) with fas-
teners from the supplementary kit and tighten ad-
equately.
Remove the RAVE valves and gaskets.
Install plates (P/N 296 000 026) with fasteners
from the kit and tighten adequately.
Install exhaust manifold plate (P/N 296 000 027).
Tighten plate using fasteners provided in the kit.
NOTE: On engines with the RAVE system, the
boot and O-ring can be checked for leakage with
the valve in place. Simply remove the cover to ex-
pose the boot.
Make sure the spark plugs are installed and tight-
en.
Block pulse hose using a hose pincher.
Install pump to the exhaust plate fitting.
1. Intake plates
2. RAVE valve plates
3. Pulse hose blocked with a hose pincher
4. Exhaust plate
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
– cylinder head gasket
– cylinder base gasket
– crankcase halves
– engine plugs
– exhaust manifold
– intake manifold
– oil injection pump.
