Anyone know how I can replace my water pump on my 1J? Ive read I could use a 2J water pump from a supra but am not sure. Mine is whining like a b*tch and makes the car sound horrible. Any guidance on this subject goes very much appreciated.

Basically, if your fan is directly bolted to your water pump (assuming you did not convert to electric fans) it is a mechanical pump. On the hydro pump, the fan is not directly attached, and run off a separate dohicky. If it's a hydro pump, you should have an extra reservoir labled fan fluid.

Go ahead and buy all the major 90k service stuff if you're getting the pump done. You can get a new GTE water pump for ~$160 and timing belt is only like $30.
