Water pump drain bolt

[Jag]

FYI. I recently drain, flushed, and refilled my cooling system. Had a small leak around the water pump drain bolt. I ordered a new copper washer and bolt from big T. Repair manual does not show copper washer but it's there. The new bolt came and has a larger bolt head and thus a larger flange, looks like an update to the original bolt. No leak now, here's some pictures. The new bolt is zinc plated the old bolt was low grade stainless steel.

It's always good to hear about upgrades and new info.

I'm more a fan of the stainless steel bolt and copper washer.
