suprastarr Posted August 18, 2013 Share Posted August 18, 2013 I broke off 2 bolts while trying to install my water pump how do I fix this? Link to comment Share on other sites More sharing options...
johnegg Posted August 18, 2013 Share Posted August 18, 2013 1) buy a left handed dirll bit slightly smaller than the blot shaft diameter and drill it out in reverse. at some point the drill bit should start to ''un-thread'' or unscrew the bolt. you might want to mark the bolt hole depth on the drill bit so you do not drill too deep. 2) buy a torque wrench and read a manual so you know what the correct torque spec is.

EJ25subie05 Posted August 18, 2013 Share Posted August 18, 2013 if you have very little mechanical experience have someone that knows what they are doing fix it. Aluminum is very easy to mess up. Link to comment Share on other sites More sharing options...

Bassnectar Posted August 20, 2013 Share Posted August 20, 2013 easy out's rarely work from what I have gathered as being in your position many times.. left handed drill bit, or a cobalt drill bit is your best option, get ear plugs may take a little bit Link to comment Share on other sites More sharing options...
