Liquid Cooling System
When filling the cooling system, use a coolant/water
mixture which will satisfy the coldest anticipated weather
conditions of the area in accordance with the coolant
manufacturer’s recommendations. While the cooling sys-
tem is being filled, air pockets may develop; therefore,
run the engine for five minutes after the initial fill, shut
the engine off, and then fill the cooling system to the bot-
tom of the stand pipe in the radiator neck.
Checking/Filling
1. Remove the two screws from the front of the radiator
access panel.
