Thread sealant for bolts holding diff cover.

[Snagglefoot]

I pulled the diff cover on a 14 Bolt Chev and noticed the last mechanic to do this applied a small amount of red sealant on each bolt about a third way down ( none on the head). The bolt holes are blind. The cover has a gasket. I'm not sure there is any advantage of putting sealant on the bolts other than helping to keep the bolts from loosening. And no, I'don't think this was thread lock). Anyone have a recommendation on this? Thanks.

Thread Sealant or Thread Locker ?

You do not need thread sealant on those bolts, they do not penetrate into anything needing sealing. I wouldn't put thread locker either. Those bolts are not going to loosen if you torque them correctly.

It was red sealant much like you find on some water pumps bolts.

Seems like there would be no reason given they're blind holes. But, blue or purple Loctite would harm nothing.

Nothing to seal . Never saw a diff cover fastener loosen and fall out .

Sounds like he was liberal with the rtv & it just got on the bolts when assembled

That discussion was on water pump bolts. This one is on diff cover bolts.
