Adding Engine Coolant; Adding Inverter System Controller - Lincoln 2014 MKZ Hybrid Owner's Manual

• Do not mix different colors or types of
coolant in your vehicle. Make sure the
correct coolant is used. Mixing of
coolants may harm your cooling
system. The use of an improper
coolant may harm the engine, inverter
system controller, and cooling system
components and may void the
warranty.
• In case of emergency, a large amount
of water without engine coolant may
be added to the engine cooling system
only in order to reach a vehicle service
location. In this instance, the engine
cooling system must be drained,
chemically cleaned with Motorcraft
Premium Cooling System Flush, and
refilled with prediluted engine coolant
as soon as possible. Water alone
(without engine coolant) can cause
engine damage from corrosion,
overheating, or freezing. DO NOT use
this method for the inverter system
controller cooling system. The inverter
system controller cooling system
operates close to ambient
temperature, and is susceptible to
freezing in any subfreezing
environment in the absence of coolant.
• Do not use alcohol, methanol, brine or
any engine coolants mixed with alcohol
or methanol antifreeze (coolant).
Alcohol and other liquids can cause
engine damage from overheating or
freezing.
• Do not add extra inhibitors or additives
to the coolant. These can be harmful
and compromise the corrosion
protection of the engine coolant.

Maintenance

Adding Engine Coolant

1. Unscrew the engine coolant reservoir
cap slowly. Any pressure will escape
as you unscrew the cap.
2. Use a funnel to add prediluted engine
coolant to the engine coolant reservoir.
Make sure that the level is between
the MIN and MAX marks on the engine
coolant reservoir. Use prediluted
engine coolant meeting the Ford
specification. See Capacities and
Specifications (page 302).
3. Close the engine coolant reservoir cap.
Whenever you add coolant, check the
coolant level in the engine coolant
reservoir the next few times you drive the
vehicle. If necessary, add enough
prediluted engine coolant to bring the
engine coolant level to the proper level.

Adding Inverter System Controller

Coolant
1. Open the inverter system controller
coolant reservoir cap.
2. Use a funnel to add prediluted coolant
to the inverter system controller
coolant reservoir. Make sure that the
level is between the MIN and MAX
marks on the inverter system controller
coolant reservoir. Use prediluted
coolant meeting the Ford specification.
See Capacities and Specifications
(page 302).
3. Close the inverter system controller
coolant reservoir cap.
