FORD 2002 Crown Victoria v.2 - Manual (Page 204)

Vehicles driven year-round in non-extreme climates should use a 50/50
mixture of engine coolant and distilled water for optimum cooling system
and engine protection.
What you should know about fail-safe cooling
If the engine coolant supply is depleted, this feature allows the vehicle to
be driven temporarily before incremental component damage is incurred.
The “fail-safe” distance depends on ambient temperatures, vehicle load
and terrain.
How fail-safe cooling works
• Standard cluster
• Optional cluster
If the engine begins to overheat:
• The engine coolant temperature gauge will move to the H (hot) area
(if your vehicle is equipped with analog gauges).
• The engine coolant temperature gauge will illuminate all eight bars
and a tone will sound every five seconds for one minute (if your
vehicle is equipped with digital gauges).
• The
symbol will illuminate.
• The Check Engine indicator light will illuminate.
