WATER PUMP

1994 Ford Tempo

There is not much space to get in to remove and replace the water pump on my 1994 ford tempo. Can anyone tell me the easiest way to do this?

Sometimes you gotta disconnect a mount and jack the engine a bit.

Not familiar with the Tempo, it lists two engines, 2.3 and 3.0, remember sometimes there's always an extra or two that may have to be taken care of to do the job once you get into it, here's both engines from what I have: Water Pump
