Oh hey I'm so on top of this sorta....there is a broken DA in my garage right now cuz it needs a new water pump- not even my car....And its snowy out.,..and my gsr is outside...any way.....
It's not that hard BUT you need a crank shaft pulley holder At least to do it on a 90 you do...or else you can't get to the pump. That's what I have to offer. Are you sure its the water pump? Cuz also I think its the heaed gasket broken on this guys DA that's in my garage- not the water pump....but nooo no one listens to the girl. (ps. the pumps not leaking and the rad builds up pressure..hmmm)
