drain cock

[cellar door]

how do I drain down the cooling system on my 8n can't seem to find a drain? Thanks

should be a block and rad drain.. sometimes the drains get broke and plugged.. in the end you can always pull a lower hose..

The pic shows a modern draincock just in front of the starter. The OEM draincock looked like a little spigot w/ a thumbscrew. A couple of my N's have pipe plugs; no draincock in the block.

Here is a pic. of the OEM drain cock:

After this one is finished being overhauled and lapped, it will be going back into my 2N block....location, is as shown in Bruces' picture.

Yep, that's the correct one for the block......it has the "B" on it.

I've never put the radiator & block drains side by side to compare the difference; any idea what it might be? I'm thinking thread pitch.

ary & Bruce:

Since Sven is all apart and most of the parts are clean, I went out & snapped this picture. The thread pitch is the same. The only difference I see in them is the color. Is it possible they made them of different metals?

1 is labeled 'R' and the other is 'B' - self evident where they go. Unlikely they are different except for the 'stampings', probly discolored from different heat ranges. (I think) HTH

Looks like brass v.s. copper in your picture, but I'm sure that's not right.
