I'm in the middle of replacing my water pump / timing belt. I thought that all of the 10mm bolts for the water pump were the same length. One of them, however, is shorter than the others. Does anybody know where this short bolt goes? I tried placing them in the water pump itself to make them all equal length, but this results in the top two shorter than the bottom two (see pic).

(This is with the short bolt on the top right, closest to the larger 14mm that is for the alternator bracket)








Bolt #19 - does it go on the top right, closest to the alternator bracket (as shown in the diagram?)

It's odd to me that the top two bolts would have significantly less length inside the block than the bottom two.

 

The short bolt goes into a short hole. Screwing it into the block at each hole should reveal where it goes.

 

It's odd because even in the FSM it doesn't show a different length bolt.




I will test them all by hand, thanks.

 

In case anyone was wondering, the short bolt goes on the bottom left hole (while looking straight at the side of the engine).
