G1988L Posted January 22, 2009 Share Posted January 22, 2009 I'm in the middle of replacing the water pump on my 88 GL Wagon, when taking off the bolts that hold on the water pump, the head on the first one broke right off no problem some vice grips fixed that, the others came out no problem (all very rusty)except one bolt is shorter than the others and after the one broke im fearing the rest of the one may still be in the block, are all the bolts the same length? if they are im in trouble, how can i fix this?

bratman18 Posted January 22, 2009 Share Posted January 22, 2009 Nope I think the lengths vary, it depends on where they bolt through the water pump. Link to comment Share on other sites More sharing options...
DaveT Posted January 22, 2009 Share Posted January 22, 2009 The holes in the block are about 1/2" deep. The bolts are different lengths, as stated previously. Link to comment Share on other sites More sharing options...
Gloyale Posted January 22, 2009 Share Posted January 22, 2009 I'd recommend buying an M6x1.00 tap, and chasing all the mounting holes. It's even beter if you grind off the *blind* portion of the tap tip, this way the tap can chase the threads all the way to the bottom of the hole. When you buy a replacement bolt(s) just get grade 5. Hardened bolts are even more likely to strip out these fragile little M6 holes. BTW there are 3 lengths of bolts. 3 short, 1 longer, 1 longest.
