Recycled Engine Coolant - Ford 1998 Ranger Owner's Manual

Maintenance and care
Check the coolant level in the coolant recovery reservoir the next few
times you drive the vehicle. If necessary, add enough of a 50/50 mixture
of coolant and water to bring the liquid level to the fill line on the
reservoir.
Never remove the coolant recovery cap while the engine is
running or hot.
If you must remove the coolant recovery cap, follow these steps to avoid
personal injury:
1. Before you remove the cap, turn the engine off and let it cool.
2. When the engine is cool, wrap a thick cloth around the cap. Slowly
turn cap counterclockwise until pressure begins to release.
3. Step back while the pressure releases.
4. When you are sure that all the pressure has been released, use the
cloth to turn it counterclockwise and remove the cap.
Use Ford Premium Cooling System Fluid E2FZ-19549–AA (in Canada,
Motorcraft CXC-8–B) or an equivalent premium engine coolant that
meets Ford specification ESE-M97B44–A. Ford Premium Engine Coolant
is an optimized formula that will protect all metals and rubber elastomers
used in Ford cooling systems for four years or 80,000 km (50,000 miles).
Do not use alcohol or methanol antifreeze or any engine coolants mixed
with alcohol or methanol antifreeze. Do not use supplemental coolant
additives in your vehicle. These additives may harm your engine cooling
system. The use of an improper coolant may void your warranty of your
vehicle's engine cooling system.

Recycled engine coolant

Ford Motor Company recommends that Ford and Lincoln-Mercury
dealers use recycled engine coolant produced by Ford-approved
processes. Not all coolant recycling processes produce coolant which
meets Ford specification ESE-M97B44–A, and use of such coolant may
harm engine and cooling system components.
Always dispose of used automotive fluids in a responsible manner.
Follow your community's regulations and standards for recycling and
disposing of automotive fluids.
