vehicle:
- Always wear eye protection .
- To reduce the ris k of burns from hot en-
gine oil let the engine cool down to the
touch.
- Whe n removing the oil drain plug with
your fingers, stay as far away as possible.
Always keep your forearm paralle l to the
ground to help prevent hot oil from run-
ning down your arm.
- Drain the oi l into a container designed
for this purpose, one large enough to
hold at least the total amount of oil in
your engine.

empty food or beverage containers that
might m islead someone into dr inking
from them.

Engine
cooling
system
Coolant
The engine coolant performs two functions: it
keeps the engine from overheating and it pro-
tects the engine from freezing in the winter.
The cooling syst em is sealed and generally re-
quires little attention.
The cooling system has been fi lled at the fac-
tory with a permanent coolant which does not
need to be changed. The coolant consists of a
mixtu re of specially conditioned water and the
manufacturer's g lycol -basedcoola nt add
i-
tive Gl 3 antifreeze with anticorrosion addi-
tives (SO% for USA mode ls; 60% for Canadian
models). This mixture both assures the neces-
sary frost protection and protects metal com-
ponents in the engine's cooling system from
corrosion and scaling.
It
also raises the boil-
ing point of t he coolant .
Do not reduce the concentration of the cool-
ant in the summer by adding plain wate r. The
proportion of coo lant additive must be at
least 50 °/4 but not mo re than 60 °/4
to main-
ta in ant ifreeze protect ion and cooling eff icien-
cy.
If
the coolant fros t protection is too low,
the coolant could freeze and damage the vehi-
cle heating and engine cooling system.
For year-round driving, antifreeze is added at
t he factory fo r temperatures down to:
- -31°F(-35°C)USA
- - 40 °F ( - 40 °C) Canada.
