Injectors leaking. Raw fuel is making its way into the exhaust through the engine. This is not safe. Take it to the dealer.
On a 1999 Mercury Grand Marquis : The Original Equipment engine cooling thermostat would have been ( around 192 * Fahrenheit )
On a 1999 Mercury Grand Marquis , 4.6 liter V8 engine : The Original Equipment engine cooling thermostat would be : ( around 192 * Fahrenheit )
According to the 2004 Mercury Grand Marquis Owner Guide : The engine cooling system capacity is ( 18 liters / 19 U.S. quarts ) It came from the factory with a 50 / 50 mix of antifreeze and distilled water
The thread on cap on the engine coolant reservoir is the pressure cap / radiator cap for the engine cooling system
In the cooling system.
The 1996 Mercury cooling fan relay switch is on the back of the cooling fan motor. The relay switch should be labeled as such.
Could be a variety of causes, but as with most cars, the top three suspects will be: old and inefficient radiator, insufficient water IN the radiator, failed thermostat governing the point at which the cooling fan cuts in.
capillarity rise.heating expands mercury whereas cooling contracts mercury
- mercury is a liquid metal - cooling and heating are easy reversible - cooling and heating are rapid - the relation between the temperature and the thermal expansion of mercury is linear
On a 1998 Mercury Tracer, the cooling fan relays are located in an engine compartment box. The compartment box should be labeled 'Cooling Fan 40 amp.'
According to the 1998 Mercury Grand Marquis Owner Guide : The engine cooling system capacity is ( 13.3 litres / 14.1 U.S. quarts ) So a 50 / 50 mix of distilled water and antifreeze would require : ( 6.65 litres / 7.05 U.S. quarts of distilled water and the same amount for the antifreeze )
The crust cooling and shrinking.
