Checking Coolant (Van Models)
The surge tank is located near the
center of the engine compartment.
See Engine Compartment Overview
on page 10‑4 for more information
on its location.
{
WARNING
Turning the surge tank pressure
cap when the engine and radiator
are hot can allow steam and
scalding liquids to blow out and
burn you badly. Never turn the
surge tank pressure cap — even
a little — when the engine and
radiator are hot.
The vehicle must be on a level
surface. When the engine is cold,
the coolant level should be at the
COLD FILL mark.
Adding Coolant (Pickup and
Van Models)
If more coolant is needed, add the
proper DEX-COOL coolant mixture
at the surge tank, but be careful not
to spill it.
{
WARNING
You can be burned if you spill
coolant on hot engine parts.
Coolant contains ethylene glycol
and it will burn if the engine parts
are hot enough. Do not spill
coolant on a hot engine.
Notice: This vehicle has a
specific coolant fill procedure.
Failure to follow this procedure
could cause the engine to
overheat and be severely
damaged.
