the library should have a shop manual for this vehicle, you can make copies of the right sections :)
To change the thermostat on a Mercury Mystique, first ensure the engine is cool and disconnect the negative battery cable. Drain the coolant and remove the necessary components to access the thermostat housing, typically located near the engine block. Remove the old thermostat and gasket, clean the surfaces, and install the new thermostat along with a new gasket. Finally, reassemble everything, refill the coolant, and reconnect the battery.
Yes, a 1995 Mercury Mystique does have a thermostat gasket. This gasket is typically made of rubber or a similar material and is used to seal the thermostat housing to prevent coolant leaks. If you're replacing the thermostat, it's advisable to also replace the gasket to ensure a proper seal and prevent overheating issues.
it is right across from my thermostat and i have a 2000 mercury cougur it srews in and out.
The thread on cap on your engine coolant reservoir is the pressure cap / radiator cap on a 1999 Mercury Mystique
"COOLANT THERMOSTAT" -COOLANT TEMP BELOW THERMOSTAT TEMPERATURE
A little more information please . What year , four cylinder or V6 , automatic or manual transmission . Then someone can probably answer your question about the coolant system capacity of a Mercury Mystique . Thanks ( also might need to know if it has air conditioning )
The engine coolant temperature sensor is usually on the front of the engine. The coolant temperature sensor will be in the vicinity of the thermostat housing.
The temperature of the coolant entering the heater core is controlled by the engine thermostat. The engine coolant thermostat is generally located at the engine end of the upper radiator hose.
Is it leaking from the side by the coolant reservoir?
Low coolant? Bad thermostat? Heater core restricted, plugged or airbound? Temperature control not working? Water pump not circulating coolant?
The thermostat in a car regulates the coolant temperature inside the engine. When the engine is cold, the thermostat is closed, allowing the heat from the combustion chamber to heat the fluid (coolant) in the coolant galleys in the engine block. Once the engine reaches an optimal temperature, the thermostat opens, allowing coolant to flow through the radiator. The thermostat then controls the flow of coolant to hold the engine at its optimum operating temperature, irrespective of engine load and operating condtions.
i have a 1999 cougar mercury vehicle that all of a sudden doesn't reverse.Why?
