GMC Terrain: Cooling System / 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 surge tank. If the coolant
inside the coolant surge tank is
boiling, do not do anything else until
it cools down. If coolant is visible
but the coolant level mark is not
visible, add a 50/50 mixture of
clean, drinkable water and
DEX-COOL coolant at the coolant
surge tank to the top rib on the
middle of the tank, but be sure the
cooling system is cool before this is
done. See Engine Overheating.
The coolant surge tank is located in
the engine compartment on the
driver side of the vehicle. See
Engine Compartment Overview.
Warning
Plain water, or other liquids such
as alcohol, can boil before the
proper coolant mixture will. With
plain water or the wrong mixture,
the engine could get too hot but there would not be an overheat
warning...
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...
Other information:
If equipped, memory seats allow two
drivers to save and recall their
unique seat positions for driving the
vehicle, and a shared exit position
for getting out of the vehicle. Other
feature positions may also be
saved, such as power mirrors and
power steering wheel, if equipped...
Utility vehicles have a significantly
higher rollover rate than other types
of vehicles. This is because they
have a higher ground clearance and
a narrower track or shorter
wheelbase than passenger cars,
which makes them more capable for
off-road driving...
