Oil Storage/Winterization; Cooling System Storage And Winterization - ILMOR MV8 Owner's Manual

SECTION 8 ILMOR MV8 OWNER'S MANUAL
8-2
NOTICE: Always perform the proper storage procedures when storing
the boat. Extended storage with fuel in the system can affect fuel
stability and may require system inspection and fuel filter replacement
when the boat returns to service. Fuel systems on all boats equipped
with Ilmor MV8 engines MUST be properly prepared for storage periods
exceeding 1 month. Owners are encouraged to seek assistance from
a certified Ilmor dealer to properly prepare the drive train for periods
of inactivity exceeding 1 month. Damage due to improper storage or
winterization preparations is not covered under warranty.

OIL STORAGE/WINTERIZATION

Contaminants in used oil can cause engine damage during storage.
Perform an oil change and run the engine to operating temperature to
allow new oil recirculation.
COOLING SYSTEM STORAGE AND
WINTERIZATION
Cooling system storage/winterization requires draining and flushing raw
water components with marine/RV antifreeze. Engines with closed cooling
systems using 50/50 propylene glycol/water mix DO NOT REQUIRE
DRAINING. The 50/50 coolant will provide freeze protection down to
−26°F (−32°C). All components which raw water flows through must be
drained. The following steps are recommended for draining of raw water
components:
Because this process should be completed while the engine is cool (in order
to avoid burns), it is recommended that this check be completed prior to
starting the engine.
1. Drain exhaust manifolds of raw water by removing the two lower
cooling hoses connected to the 90° fittings.
2. Drain engine block of raw water.
For open cooled 5.7L applications: Remove knock sensors/drain
•
plugs from both sides of the engine block.
• For 6.0L, 6.2L and 7.4L applications: Remove drain plugs from
both sides of engine drain hoses.
3. Drain heat exchangers of raw water.
• Open cooled systems will have an oil/transmission heat exchanger.
Remove the drain plug and allow the cooler to completely drain.
• Closed cooled systems will have an oil/transmission and engine
heat exchanger. Remove the drain plug and allow the cooler to
completely drain.
