Section 4 - Lubrication & Maintenance
Every 2000 Hours or 2 Years
To remove the coolant in the engine block, disconnect the lower radiator hose (4) from the base of the radiator.. This will drain whatever coolant is in the water jacket of the engine..
Drain all the coolant into a suitable container and follow all local laws and regulations for disposal..
Turn off the coolant filter shutoff valve so the filter is isolated from the cooling system during cleaning and flushing operations..
IMPORTANT: Failure to isolate the cooling system filter by closing the shutoff valve will contaminate the cooling system filter, and the filter will have to be replaced whether its change interval has been reached or not.
Flushing the Cooling System
Refer to page
After the cooling system is cleaned, retighten the petcock (3) and reinstall the lower radiator hose (4).. Open the cooling system filter shutoff valve (5)..
