Daston Posted January 19, 2007 Share Posted January 19, 2007 Ok after shering 2 studs off my water pump I have been thinking why do they use studs and not a bolt? Is it due to vibrations or somethin Quote Link to comment Share on other sites More sharing options...
merckx Posted January 19, 2007 Share Posted January 19, 2007 Dunno, I've never taken my water pump off. But it's often easier to locate something if studs are fitted, better than fiddling around trying to get bolts to go in. I might be wrong, I'll let you know when I remove my pump.

Chewie Posted January 19, 2007 Share Posted January 19, 2007 I agree with mercx. As a design engineer, I would use studs for location assistance. Are you frequently shearing studs? If so check the torque wrench calibration - if you're using one. If not then it's no wonder they're breaking. Quote Link to comment Share on other sites More sharing options...
Daston Posted January 19, 2007 Author Share Posted January 19, 2007 My old man told me it was because I was using a socket and not a spanner as the spanner should put less leverage on it. My main reason for asking was because my local halfords is a fair way away so cant get any studs but have a shed load of bolts Quote Link to comment Share on other sites More sharing options...
Chewie Posted January 19, 2007 Share Posted January 19, 2007 As they're holding a water pump I'd imagine it's probably more to do with heavily corroded threads than anything else. You'd shear bolts if the corrosion was severe enough. Just be careful. Quote Link to comment Share on other sites More sharing options...
Daston Posted January 19, 2007 Author Share Posted January 19, 2007 Yeah learnt my lesson drowed it all in WD40 and they have come out now. Will bung 2 bolts in there to hold the thermostat housing in whilst I go to halfords Quote Link to comment Share on other sites More sharing options...
