Cabin Heating Coolant
System
Cabin heating uses a separate
coolant system.
When cabin heating is requested,
the heater and heater coolant pump
are turned on to circulate warm
coolant through the heater core.
What to Use
The heater coolant reservoir in the
vehicle is filled with a 50/50 mixture
of DEX-COOL coolant and
deionized water. If using this
mixture, nothing else needs to be
added.
The coolant needs to be replaced
at the appropriate interval. See
Maintenance Schedule on
page 11-2
.
Checking Coolant
The vehicle must be on a level
surface when checking the coolant
level.
The heater coolant reservoir is in
the underhood compartment. See
Underhood Compartment Overview
on page 10-6

Check to see if coolant is visible
in the heater coolant reservoir.

level is below the cold fill line, there
could be a leak in the system.
The heater coolant should only be
serviced by a qualified technician.
Washer Fluid
What to Use
When windshield washer fluid is
needed, be sure to read the
manufacturer's instructions before
use. If operating the vehicle in an
area where the temperature may fall
below freezing, use a fluid that has
sufficient protection against
freezing.
