Stripped hole repair
I have a 2006 Chrysler Sebring convertible with the 2.7L engine that needs a
new water pump. One of the bolt holes that takes a bolt that passes through
the timing chain cover and throught the water pump has become stripped. I
messed up trying to drill and tap it and use a heli-coil; the heli-coil won't hold.
Any suggestions on how to repair the hole? I am considering re-drilling and
tapping and using a larger bolt, but there is only so much leeway throung the
water pump. I have also seen some things about filling the hole with J B
Weld and either waxing and setting a lubricated bolt in it while it cures to
form new thread or to re-drill and tap it.
