Re: Water pump replace, broke 2 bolts! HELP!
<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: r2j2</div><div class="ubbcode-body">Put the new water pump on yesterday. Torque spec was 35-45 ft/lbs. I torqued all 9 bolts to 40 lbs. Test drove and one of the bottom bolts (driver side) was seeping. Rolled under the truck with the torque wrench set at 45 lbs and the bolt tightend some more. Never did hit the stop on the torque wrench with that bolt. Got up on top and started checking the other ones and broke 2 trying to retorque the bolts.
Now I am kind of in trouble because one of the two that broke is a long one (there are three lengths) and the broken off part is deep in the hole in the block. I havenít taken the pump back off yet so I donít know if the other one is proud of the machined face but the long bolt I am sure is deep in there.
1) What could have caused these bolts to break? The engine was hot after just test driving, could this be a factor?
2) Any suggestions as to how to deal with the broken off bolt deep in the long hole?
My last resort is to remove the broken one that should be right at the face, replace all bolts with new ones, and use RTV in the gasket area for the broken one and not have a bolt there.
Please help, I feel like someone just kicked me HARD!
</div></div>Where did you read the procedure to torque those bolts to 35-45 ftlbs. That is way to high. For a while the article on this site recommended that torque but after vocal criticism it was finally corrected to 15-22 ftlbs. Look here.
