I am about to replace the water pump but according to the info that i have, the 4 bolts that mount the pump to the block are torque to yields. I have them on order right now but that puts the project off for 2 weeks. in the duration of the research part, a friend called the dealer and several part stores and I get conflicting info on whether or not they are really that type. if I can reuse them with out potential of damage, that would be nice but if they are torque to yields, id just as soon replace replace them at that point. are they or are they not TTYs?
