When I take the water pump off do I

the reason im trying to take the water pump off is that when i got the car the alt.bolt that goes through the water pump is broke off inside..

Does anyone know if the bolt is threaded in the water pump or just goes through the pump and threads into the block?

There was not enough bolt left to try anything so i grinded it down and the pump is stuck. I can wiggle it a little but nothing else..
 
I'm pretty sure that the alternator bolt goes into the RH head. It most likely broke off roughly even with the front of the head. Once the alternator is removed, you should be able to center punch the broken bolt, center drill it and finally use and 'easy-out' to remove it. It would be a good idea to retap the hole before installing a new bolt.

If I remember correctly, the upper alternator bolt does not go through the water pump but instead goes throught the bracket and into the head. The lower bolt goes through a clearance hole in the timing cover I think.
I could be way off here though.

If you do have to remove the pump, loosen the shroud (if you have one), move it rearward, and then unbolt the fan. Put a piece of cardboard between the front of the fan and the radiator to keep the fins from getting bent and to keep the skin on your knuckles. :D
 
the upper alternator bracket bolts to the water pump. But yeah, the alternator itself bolts thru the bracket to the head. I don't remember if the bolts for the upper bracket thread into the water pump or just pass thru it on their way to the timing cover or block.
 
The bolt that goes through both alternator brackets (lower arm and main fixed) is a long and thin bolt, which is easy to twist off. If this is the bolt you are talking about, then yes it goes through the waterpump and threads into either the timing cover or the block (leaning more towards the block).
 
It sounds a little lame, but is really easy to forget which bolt goes where in the waterpump/timing cover. If you have not already removed the bolts, it might be a good idea to poke them through a piece of cardboard in aprox. the same position as on the engine. It might save you half an hour later when you reassemble it.
