Recycled Engine Coolant - Ford Mustang 2001 Owner's Manual

Maintenance and care
10. If necessary, add a 50/50 mixture of engine
coolant and distilled water to the engine coolant
reservoir until the coolant level is at the "cold fill
level" as listed on the reservoir.
After any coolant has been added, check the coolant
concentration see Checking Engine Coolant section).
If the concentration is not 50/50 (protection to
–34°F/–36°C), drain some coolant and adjust the
concentration. It may take several drains and
additions to obtain a 50/50 coolant concentration.
Whenever coolant has been added, the coolant level in
the coolant reservoir should be checked the next few
times you drive the vehicle. If necessary, add enough
50/50 concentration of engine coolant and distilled
water to bring the liquid level to the proper level.
If you have to add more than 1.0 liter (1.0 quart) of
engine coolant per month, have your dealer check
the engine cooling system. Your cooling system may
have a leak. Operating an engine with a low level of
coolant can result in engine overheating and possible
engine damage.

Recycled engine coolant

Ford Motor Company recommends the use of a
recycled engine coolant produced by Ford-approved
processes in vehicles originally equipped with
Motorcraft Premium Engine Coolant (green-colored).
However, not all coolant recycling processes produce
coolant that meets Ford specification
ESE-M97B44–A. Use of such coolant may harm the
engine and cooling system components.
Ford Motor Company does NOT recommend the use
of recycled engine coolant in vehicles originally
equipped with Motorcraft Premium Gold Engine
Coolant since a Ford-approved recycling process is
not yet available.
Used engine coolant should be disposed of in
an appropriate manner. Follow your community's
regulations and standards for recycling and disposing
of automotive fluids.
