Ford 1999 F-350 Automobile User Manual


 
DO NOT MIX recycled coolant and conventional coolant
together in your vehicle. Mixing of engine coolants may harm
your engine’s cooling system.
The use of an improper coolant may harm engine and cooling
system components and may void the warranty of your vehicle’s
engine cooling system.
Use only the type of coolant with which your vehicle was
originally equipped. If you are unsure which type of coolant
your vehicle requires, contact your local dealer.
Do not put engine coolant in the container for the windshield
washer fluid.
If sprayed on the windshield, engine coolant could make it difficult to see
through the windshield.
When the engine is cool, add a 50/50 mixture of engine coolant and
distilled water to the engine coolant reservoir.
Plain water may be added in an emergency, but you must replace it with
a 50/50 mixture of coolant and distilled water as soon as possible.
Check the coolant level in the coolant reservoir the next few times you
drive the vehicle. If necessary, add enough of a 50/50 mixture of coolant
and distilled water to bring the liquid level to the fill line on the
reservoir.
Never remove the coolant reservoir cap while the engine is
running or hot.
If you must remove the coolant reservoir 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.
Change your engine coolant according to the appropriate schedule listed
in the Scheduled Maintenance Guide.
