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 coolant reservoir is filled with a
50/50 mixture of DEX-COOL coolant
and deionized water. See
Recommended Fluids and
Lubricants on page 11-8. 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 reservoir is in the underhood
compartment. See Underhood
Compartment Overview on
page 10-6.
Vehicle Care

the coolant level is below the cold
fill line, there could be a leak in the
system.
How to Add Coolant to the
Coolant Reservoir
If no problem is found, add the
proper DEX-COOL coolant mixture
at the coolant reservoir.
