View Full Version : 22re water pump query

05-07-2009, 02:27 PM
busted off the head off an old water pump bolt so i decided to buy all new wp hardware from toyota.

my question concerns the three studs and the one stud which seems to have plastic between its threads. i am wondering where this one goes, if the plastic needs to be inserted inside the housing or if it simply helps lock the nut to the threads outside the pump?

if anyone has a good diagram or atleast better than toyotas i would be very grateful since it seems to me the hardware on mine right now seems to be mixed and matched - and the employees at toyota are of no real help.

thanks alot

its been a while, but if not mistaken, there is 7 outer bolts, and 2 within the circumference of the pump housing. one of these 2 passes through the timing cover to the block. this would be the bolt with the plastic on the thread, (thus to seal it) if its a 12mm bolt, its the one on the right. if its only a 10mm head, its the one on the left.
