If the coolant inside the coolant surge tank is
boiling, do not do anything else until it cools down.
The vehicle should be parked on a level surface.
{CAUTION:
Heater and radiator hoses, and other
engine parts, can be very hot. Do not
touch them. If you do, you can be burned.
Do not run the engine if there is a leak. If
you run the engine, it could lose all
coolant. That could cause an engine fire,
and you could be burned. Get any leak
fixed before you drive the vehicle.
If there seems to be no leak, with the engine on,
check to see if the electric engine cooling fans
are running. If the engine is overheating, both fans
should be running. If they are not, your vehicle
needs service.
Notice: Engine damage from running your
engine without coolant is not covered by your
warranty. See Overheated Engine Protection
Operating Mode on page 353 for information on
driving to a safe place in an emergency.
Notice: Using coolant other than DEX-COOL
®
may cause premature engine, heater core,
or radiator corrosion. In addition, the engine
coolant could require changing sooner, at
30,000 miles (50 000 km) or 24 months,
whichever occurs first. Any repairs would not
be covered by your warranty. Always use
DEX-COOL
®
(silicate-free) coolant in your
vehicle.
How to Add Coolant to the Coolant
Surge Tank
If you have not found a problem yet, check to see
if coolant is visible in the surge tank. If coolant
is visible but the level is not at the FULL COLD
mark located on the side of the surge tank,
add enough of a 50/50 mixture of clean, drinkable
water and DEX-COOL
®
coolant at the coolant
surge tank to bring the level to the FULL COLD
mark, but be sure the cooling system, including the
coolant surge tank pressure cap (if equipped), is
cool before you do it. See Engine Coolant on
page 347 for more information.
