General Periodical maintenance
– 89 –
NOTE: All new vehicles are
factory filled with a 50% anti-
freeze solution which will give
frost protection down to -34
°
F
(-36
°
C).
CAUTION: The use of anti-
freeze that does not conform
to the required specification
can cause severe damage to
the cooling system and its
components.
The anti-freeze mixture must remain
in the cooling system during the
summer months.
I
1. Remove the filler cap from the
surge tank.
2. Using 2-way test strips, perform
freeze point and nitrite level tests
per coolant supplier’s recommen-
dations. Supply additives and cool-
ant/water mixture as indicated.
CAUTION: Damage to the
engine and cooling system,
such as corrosion and cavi-
tation erosion, will occur
unless antifreeze ZEREX
PENRAY 2792 is used and
maintained with supplemen-
tal coolant additive Pencool
3000 with Stabil-Aid. As
needed, fill or top off the
cooling system only with a
ready-mixed clean water/
approved antifreeze solution
using these products. The
use of other antifreeze prod-
ucts will void your engine,
radiator, and cooling system
warranties.
3. The cooling system should be filled
with ready-mixed clean water/anti-
freeze solution which conforms
with the required specifications.
