Checking Coolant
The vehicle must be on a level
surface when checking the coolant
level.
Check to see if coolant is visible in
the coolant recovery tank. If the
coolant inside the coolant recovery
tank is boiling, do not do anything
else until it cools down. If coolant is
visible but the coolant level is not at
or above the FULL COLD mark, add
a 50/50 mixture of clean, drinkable
water and DEX-COOL coolant at the
coolant recovery tank, but be sure
the cooling system is cool before
this is done. See Cooling System on
page 10‑15 for more information.
The coolant recovery tank cap has
this symbol on it.
When the engine is cold, the coolant
level should be at or above the
FULL COLD line marked on the
recovery tank.
When the engine is hot, the
level could be higher than the
FULL COLD line. If the coolant is
below the FULL COLD line when
the engine is hot, there could be a
leak in the cooling system.
If the coolant is low, add the coolant
or take the vehicle to a dealer for
service.
How to Add Coolant to the
Recovery Tank
{
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.
If coolant is needed, add the proper
DEX-COOL coolant mixture at the
coolant recovery tank.
