You cant really. I have a 1996 Mercury Villager LS 3.0L. The only thing that you notice is a bit less shakyness when shifting (automatic trans). Also the take off will be more smooth and you will feel like you are gettin more power at high speeds or a WOT (wide open throttle). If you mean physically in overdrive at the shifter, you can't. The quadrant is marked with only "D", "2" and, "1". You must assume that it will shift into overdrive when all conditions are met and the computer allows the trans to shift. If you mean how do you know when the trans has shifted into overdrive, there are two ways. First, count the shifts. For overdrive, there will be three shifts. Or, if yours is equiped with a tachometer, watch it for the shift points.
The Z24 has overdrive, the base models are 3 speed autos
can you tell me where the knock sensor is located on a 3.3l mercury villager
Anyplace that sells batteries can tell you the correct size you need.
Normally it is not the swaybar itself but the bushings. You have a set of two on each side of the car, an upper and lower. Fairly easy to do. About 8 bucks for each set.
One way would be to take the VIN number to a Ford dealer, they would be able to tell.
A bad ignition switch, on your 1995, Mercury Voyager, will cause the vehicle not to start. In most cases a bad ignition will cause the engine not to turn over.
IF the computer was really defective, either the car would not run, or there would be a check engine light due to a fault code.
Look inside the driver side door jam is should tell you tire sizes. If you cannot find it, refer to your owners manual.
If the timing belt was broken, obviously the engine would not run. If you crank the engine and the distributor does not turn, that would be a good sign.
Go to your local parts house or Walmart, Pepboys, ect. and get trans fluid for a Ford automobile. The bottle will tell you it is for Ford autos.
If it's leaking and squealing, it's bad. If it's not, it's probably OK. It should be changed when you change the timing belt.
