4. Replace the radiator breather cap and the
coolant system cap and tighten to the first
stop.
5. Start and idle the engine until the radiator
upper hose is warm. The warm hose
indicates the thermostat is open and the
engine coolant is flowing through the entire
system.
6. Shut the engine off and check the fluid level
in the radiator through the coolant system
cap opening. Add more fluid if necessary.
7. When the radiator is filled to the proper
level, replace the coolant system cap and
tighten both caps completely.
Checking hoses
Check all engine and heater system hoses and
hose connections for deterioration, leaks, and
loose hose clamps as specified in the
maintenance schedule. Repair or replace with
Motorcraft hoses or equivalent as necessary.
Windshield Washer Fluid and
Wipers
Washer Fluid
Check the level of the windshield washer fluid
every time you stop for fuel. The reservoir for
the windshield washer fluid is located in the
engine compartment. Visual inspection can
determine if the washer fluid is adequate. Do
not operate the washer when the reservoir is
empty.
