Pull the valve slightly. Using pliers, release the clamp which retains the bellows.
Remove valve and bellows.
Inspection
Inspect parts for damage. Verify especially bel-lows for cracks.
Assembly
Assembly is essentially the reverse of disassem-bly procedures.

GENERAL
The cooling system is equipped with a fitting spig-ot for flushing purposes (a hose adapter for the HX model).
For flushing operation, a coupler hose is available (unnecessary for the HX model) to connect to fit-ting spigot. The other end of coupler hose is to be connected to a garden hose to flush the whole system by backwash. For flushing procedure, re-fer to MAINTENANCE 02-02.
For winterization of cooling system, refer to MAINTENANCE 02-04.
Special precautions should be taken when towing a Sea-Doo watercraft.
When towing your watercraft pinch the water supply hose from the impeller housing to the en-gine with the Hose Pincher (large) Pþ/þN 529 030 400.
This will prevent the cooling system from filling which may lead to water being injected into and filling the exhaust system. Without the engine running there isn’t any exhaust pressure to carry the water out the exhaust outlet.
CAUTION : Failure to do this may result in damage to the engine. If you must tow a stranded watercraft and do not have a hose pincher be sure to stay well below the maxi-mum towing speed of 24 kmþ/þh (15 MPH).
When finished towing the craft you must remove the hose pincher before operating it. Failure to do so will result in damage to the engine.
The water supply is taken from a pressurized area in the jet pump between the impeller and venturi.
The tuned pipe and exhaust manifold are de-signed with a double wall to allow water circula-tion.
Water is pre-heated by the exhaust system be-fore entering the cylinder cooling jackets.
When engine is running, water must flow from bleed outlet(s) indicating that water circulates.
Check monitoring beeper operation by jumping terminal of thermosensor wire to ground. Beeper must operate.
At every verification of monitoring beeper always apply dielectric grease on thermosensor connec-tor.
Verify wire terminal on connector for tightness. If too loose, squeeze terminal slightly at installation.
CAUTION : When investigating for no wa-ter flow in the cooling system, check all el-bows and straight fittings as well as all hoses for blockage.
When servicing the hull, always rotate watercraft counterclockwise (seen from the rear). Rotating watercraft clockwise could allow residual water in tuned pipe to enter the engine and cause damage.
717 and 787 Engines Only
These engines have a Serial Cooling System ; fresh water enters the cylinder head assembly, cooling the combustion chamber to prevent deto-nations. Then, water exits cylinder head toward tuned pipe.
1. Cylinder head cover 2. Fresh water from jet pump
3. Water exiting head assembly to tuned pipe, exhaust manifold and cylinders
A. Water from cylinder water jackets exiting engine
05-02-2
For a minimum back pressure in the exhaust, en-gine water outlet hose is not connected to the ex-haust. It has its own fitting at the rear of the hull.
1. Engine water outlet hose
All engines
Water enters cylinder cooling jacket through pas-sages located below exhaust ports from tuned pipe.
1. Water passages
No water enters crankcase.
For a complete view of cooling system arrange-ment, refer to the next pages for each engine model.
CAUTION : Never modify cooling system ar-rangement, otherwise serious engine dam-age could occur.
