Stripped bolt

On the TD that I own, the threads on the engine block are stripped
where one of the bolts mount the water pump to the engine. My
question
to the group - is it better to drill & tap to the next larger size
bolt
or use a helicoil?
Any expierience/advise would be appreciated.
Thanks,

Dave,
I had the exact same problem with my TD about 25 years ago. I don't know if
they had helicoil back then or if I simply wasn't aware of it, but I tapped
it out to 10 mm. It solved the problem. But if it happened to me today, I'm
sure I'd opt for the helicoil solution!

Dave,
No question in my mind, do it right, use a Helicoil, 8.0 x 1.0 MM Metric
fine thread. These kits are readily available at good fastener stores. Now
you can also repair all those stripped holes in the bell housing and timing
chain cover using the correct Helicoil inserts.
Before I would drill and tap to the next size, I would use 8.0 x 1.25 mm
standard metric thread , or 5/16"- NF helicoil. These are bastard sizes for
the XPAG but better than tapping to the next sizes.
Remember there is not a lot of room under the water pump and the next size
nut will be harder to get a wrench onto, especially if its the bolt holding
the engine steady bracket.

Dave:
Go the 8mm helicoil route.
