Caution
If coolant is changed or added,
always add enough to fill the
system completely or engine
damage may occur.
If more coolant is needed, add the
proper DEX-COOL coolant mixture
at the surge tank, but be careful not
to spill it.
{
Warning
Spilling coolant on hot engine
parts can burn you. Coolant
contains ethylene glycol and it will
burn if the engine parts are hot
enough.
{
Warning
Steam and scalding liquids from a
hot cooling system are under
pressure. Turning the pressure
cap, even a little, can cause them
to come out at high speed and
you could be burned. Never turn
the cap when the cooling system,
including the pressure cap, is hot.
Wait for the cooling system and
pressure cap to cool.
If no coolant is visible in the surge
tank, add coolant as follows:
