I have isolated a root cause of leaking antifreeze,posted previously.
It is due to a drip coming from the retapped side plate bolt which
holds the alternator bracket. This was snapped off when installing
a new arm the the indigo alternator and ratapped.
I did not notice the leak until now.
The engine has always 20 years at least, probably from begining when new
been fresh water cooled.
At Don's suggestion, I have ordered the replacement side plate with
welded on bracket. But I don't want to mess with this until after haulout,
Because I have trips coming up starting next week
I need a one season temporary fix.
especially since the one I did retap is dripping.
Don suggested using aviation permatex on the bolt and using a solid
bronze washer, not a split lock washer. He also mentioned letting
the aviation thicken over night.
Since the aviation permatex I have had been previously opened, I tried
it yesterday with 10 min air cure. It did not stop the dripping.
The order which I tired was : bronze washer, bracket and bolt.
I had coated the bolt very generously first.
There is antifreeze present at the bracket bolt hole
Any suggestions appreciated
Thanks
