What engine do you have? There are actually several of them on both sides and they are round and of stamped metal.

Coolant drain plugs, not freeze plugs. One on the straight 6, two on the V8. That on the I-6 should be on the slanted side. Those on the V8 are on the outside. V8 driver side shown below the second hole.

Passenger side behind the sheathed thick battery cable to the starter.

Yep. It's on the passenger side right underneath the 6th (rear) cylinder on the block (if it's a 6 cylinder).

Be ready when you take it out. There is quite a bit of coolant in the block and it comes out quick
