Add engine coolant as follows:

8 Thermostat Housing Plug

Remove thermostat housing plug. Add cool- ant to radiator until coolant is at bottom of fill- er neck and coolant trickles out of thermo- stat housing plug hole. This ensures all air is purged from the system.

Reinstall plug and radiator cap. Check cool- ant level in overflow bottle.

Engine coolant is a mixture of water and ethylene glycol base antifreeze. A solution of 50% antifreeze and 50% water must be used in this engine. Do not use 100% anti- freeze or severe damage will occur.
