child seat FORD MONDEO 1993 Service Repair Manual

pleated-paper type filter, it cannot be washed
or re-oiled. If it cannot be cleaned
satisfactorily with compressed air, discard
and renew it.
Warning: Wear eye protection
when using compressed air!
8Refitting is the reverse of the removal
procedure; ensure that the element and
housing are securely seated, so that unfiltered
air cannot enter the passenger compartment.
Note:If the antifreeze used is Ford’s own, or of
similar quality, the coolant need not be
renewed for the life of the vehicle. If the
vehicle’s history is unknown, if antifreeze of
lesser quality is known to be in the system, or
simply if you prefer to follow conventional
servicing intervals, the coolant should be
changed periodically (typically, every 2 years)
as described here. Refer also to the
information in Section 2 of this Chapter.
Warning: Do not allow antifreeze
to come in contact with your skin
or painted surfaces of the
vehicle. Flush contaminated areas
immediately with plenty of water. Don’t
store new coolant, or leave old coolant
lying around, where it’s accessible to
children or pets - they’re attracted by its
sweet smell. Ingestion of even a small
amount of coolant can be fatal! Wipe up
garage-floor and drip-pan spills
immediately. Keep antifreeze containers
covered, and repair cooling system leaks
as soon as they’re noticed.
Warning: Never remove the
expansion tank filler cap when
the engine is running, or has just
been switched off, as the cooling system
will be hot, and the consequent escaping
steam and scalding coolant could cause
serious injury.
Coolant draining
Warning: Wait until the engine is
cold before starting this
procedure.1To drain the system, first remove the
expansion tank filler cap (see Section 3).
2If the additional working clearance is
required, raise the front of the vehicle and
support it securely on axle stands.
3Remove the radiator undershield (eight or
nine screws), then place a large drain tray
underneath, and unscrew the radiator drain
plug; direct as much of the escaping coolant
as possible into the tray (see illustrations).
System flushing
4With time, the cooling system may
gradually lose its efficiency, as the radiator
core becomes choked with rust, scale
deposits from the water, and other sediment
(refer also to the information at the start of
Section 2). To minimise this, as well as using
only good-quality antifreeze and clean soft
water, the system should be flushed as
follows whenever any part of it is disturbed,
and/or when the coolant is renewed.
5With the coolant drained, refit the drain plug
and refill the system with fresh water. Refit the
expansion tank filler cap, start the engine and
warm it up to normal operating temperature,
then stop it and (after allowing it to cool down
completely) drain the system again. Repeat as
necessary until only clean water can be seen
to emerge, then refill finally with the specified
coolant mixture.
6If only clean, soft water and good-quality
antifreeze (even if not to Ford’s specification)
has been used, and the coolant has been
renewed at the suggested intervals, the above
procedure will be sufficient to keep clean the
system for a considerable length of time. If,however, the system has been neglected, a
more thorough operation will be required, as
follows.
7First drain the coolant, then disconnect the
radiator top and bottom hoses. Insert a
garden hose into the top hose, and allow
water to circulate through the radiator until it
runs clean from the bottom outlet.
8To flush the engine, insert the garden hose
into the thermostat water outlet, and allow
water to circulate until it runs clear from the
bottom hose. If, after a reasonable period, the
water still does not run clear, the radiator
should be flushed with a good proprietary
cleaning agent.
9In severe cases of contamination, reverse-
flushing of the radiator may be necessary. To
do this, remove the radiator (Chapter 3), invert
it, and insert the garden hose into the bottom
outlet. Continue flushing until clear water runs
from the top hose outlet. A similar procedure
can be used to flush the heater matrix.
10The use of chemical cleaners should be
necessary only as a last resort. Normally,
regular renewal of the coolant will prevent
excessive contamination of the system.
Coolant filling

flushed, ensure that all disturbed hose unions
