I didn't read any torque specs for the 6-mm bolts on the WP. I looked it up for threads w/lubricant and the value was 9 ft-lb.
It is strange that there are 6-mm bolts also on the water pump. especially since the two top ones are 6-mm. With different torque values, the pump would be asymmetrically loaded.
I tightened them to that value but one bolt seemed to "keep going".
I stopped and checked the wrench on another 6-mm bolt and it clicked fine (I have one of those clicking torque wrenches).
I should have stopped.
So I went back to the bolt and made another turn with the wrench but then the head sheared off.
The bolt must have been over-tightened previously .. hmm but that would have been at the factory since I was removing the original WP.
I hope I don't have to take the WP off soon, because it is the lower 6-mm bolt and I don't even know if I can a drill in there to tap the hole and extract it.
Hopefully with 425,000 mi. on the vehicle, I won't need to worry about that since I hope to have enough money saved away for my Enzo Ferrari.
kidding ..... of course
