What size engine is in 1995 ford contour SE?

More than likely the engine in the car is the 6 cylinder 2.5 Liter engine. An easy way to tell is to look at the instrument cluster. To the left of the speedometer should be a tachometer on 6 cylinder models. On the tachometer on the top will be a V-6. If there is no tachometer or a tachometer that doesn't say V-6 the engine is a Inline 4 cylinder 2.0 liter engine.
