Silicone sealant on anode retaining bolt

[macedonia]

I've searched the forum but couldn't find a discussion of this subject.

The Suzuki Service Manual for a 2007 DF140 states that the anode retaining bolt should be covered with Suzuki silicone sealant (page 2-18). The implication is that even the internal anodes should get this treatment. I've applied the sealant to external anode bolts and the ones on the rectifier (there are two other internal ones that I've not be able to remove yet). According to the manufacturer's specs, their silicone sealant can withstand 392 degrees F for 10,000 hours and over 650 deg F for short periods. Still, applying sealant to the internal anode bolts seems counter intuitive.

Does anyone have experience with applying the sealant to the internal anode retaining bolts?

Thanks,
Nick

I've attached a screenshot of the service manual page to help in understanding if the silicone sealant should be applied to the internal anodes.

Thoughts?

Resolved. The silicone should not be used on the internal anode retaining bolts.

I don't follow...

Since the service manual says to apply the silicone seal to the anode retaining bolt head how did you arrive with the resolution to NOT APPLY the silicone to the retaining bolts??

IMHO; The picture shows the securing bolt going through anode being covered only at the top and no further than the recession in the anode. The other bolts would be the cover bolts, and not the anode securing bolt. I think the idea is to protect the bolt from corrosion so it can be removed later.
