CHEVROLET 2010 HHR - Manual (Page 325)

Checking Coolant
The vehicle must be on a level surface when checking
the coolant level.
The coolant recovery tank
cap has this symbol on it.
The tank is located in
the engine compartment
toward the front of the
engine on the passenger’s
side of the vehicle.
See Engine Compartment Overview on page 6-16 for
more information on location.
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 COLD FILL 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.
When the engine is cold, the coolant level should be at
the COLD FILL (A) line or a little higher. The COLD
FILL line is near the bottom of the tank and sticks out
from the rear of the tank.
When the engine is cold, the coolant level should be at
or above the COLD FILL line. If it is not, you may
have a leak in the cooling system.
