This replacement of the water pump requires you to remove the timing belt to access and replace the water pump.In short the timing belt runs the water pump.And in order to do this requires removing the air charge pipes,both upper and lower timing cover,the fan clutch assembly,and fan shroud for room.You also have to drain the coolant and ensure the number 1 is in alignment with the raised arrow at the camshaft and the the notch at the crankshaft is lined up perfect with the mark on the crankshaft gear.This is not a novice job and even ifa manual can help I would suggest going to a shop if you are not mechanically inclined to do it.There are some steps I left off but,with a short version this should help you better understand the time,knowledge of taking on this task which is not easy even though this engine is pretty simple overall.

Hi Make sure it is not an after market pump, I put four after market pumps in my 92 until I was told to use a Mazda pump, all is running good.
