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 system is sealed and genera lly re-
quires little attention.
The cooling system has been filled at the fac-
tory with a permanent coolant which does not
need to be changed . The coolant consists of a
mixture of specially conditioned water and the
manufacture r's glycol-basedcoo lant add i-
t ive
Gl3 antifreeze with anticorrosion addi-
t ives (SO% for USA models; 60% for Canadian
models). This mixture both assures the neces-
sa ry frost protection and protects metal com-
ponents in the eng ine's cooling system from
corrosion and scaling.
It also raises the boil-
ing point of the coolant .
Do not reduce the concentration of the cool-
ant in the summer by adding plain water .
The
proportion of coolant additive must be at
least 50 % but not more than 60°/o to main-
tain ant ifree ze protect ion and cooling efficien-
cy.
If the coolant fros t protec tion is too low
'
t he coolant could freeze and damage the vehi-
cle heating and engine cooling system. ..,.
