1200 HOUR/2 YEAR SERVICE (continued)
- Tractors without Coolant Filter
With the engine cool, drain and refill the cooling
system,
.as
follows:
A
WARNING: Coolant should be kept off
aa
the ski.n. Adhere to the precautions out-
li111td on the antifreeze container.
Open the radiator drain cock, f:igure 70 and allow
the coolant to drain. Unscrew and remove the
drain plug, Figure 71 and drain the coolant from
engine block. Remove the radiator cap at this stage
to increase the drainage rate.
NOTE: Some models may have a drain cock in
place of the plug shown in Figure
7 J.
If
so, open
the cock to drain the coolant from the block.
After flushing, close the drain cock(s) and/or re-
place the engine coolant drain plug. Refill the
cooling system via the radiator filler tube using a
50% solution
of
clean water and
antifreeze
premixed with 5% inhibitor. The inhibitor is avail-
able from Ford New Holland dealers under the
part No. FW-15. It is supplied in 16 fl. oz. (473
ml) bottles, the side of the.bottle being marked in 1
fl.
oz.
increments.
IMPORT ANT: Anti-leak additives should be
avoided. The clogging properties of these addi-
tives could affect the performance of the filter.
Mix FW-15 inhibitor with clean water and pcnn'a-
nent antifreeze in the following proportions:
Water Antifreeze
Inhibitor
U.S. Gal.
1.0
1.0
13
oz.
Imp. Gal.
1.0
1.0 16
oz.
Litres
4.0
4.0 12 oz.
Check that the coolant level is flush with the indi-
cator at the bottom of the filler tube
(sec
Operation
5). See Section C for cooling system capacity,
clean water properties and antifreeze specifica-
tion.
NOTE: To avoid trapping air in the system.fill the
radiator as slowly as practicable thereby allowing
any air pockets to disperse.
Start and run the engine to circulate the coolant.
Stop the engine and top up the radiator with the
same solution of clean water, antifree:1..c and in-
hibitor.
NOTE: The coolant level may drop as it is
pumped around the cooling system.
A
WARNING: The cooling system oper-
41A
ates under pressure which is controlled
by the radiator cap. It is dangerous to remove tlze
cap while the system is hot. Use a thick cloth and
turn the cap slowly to the first stop and allow
the pressure to escape before fully removing the
cap. Coolant should be kept off the skin. Adhere to
the precautions outlined on the antifreeze and in-
hibitor containers.
IMPORTANT: It is essential that a Ford New
Holland approved cap is used.
If
the cap is mislaid
or damaged, obtain a replacement from your
Ford New Holland dealer.
If the engine is not going to be operated immedi-
ately following this coolant change, run the engine
for one hour
to
ensure that the chemical inhibtor is
dispersed throughout the cooling system. Allow
the engine to cool and make a final check
lo
ensure
that the coolant level is satisfactory.
