Location Of Driver Side Coolant Draincock '99 Ls400?

[AZ Mike]

I found the engine block coolant draincock on the passenger side, but I don't see the draincock on the driver's side. Can anyone with a 2nd generation LS tell me where it is located?

Also, on the passenger side, it appears that there is a large bolt that threads into the engine block and has the hose nipple attached to it, and what appears to be a smaller nut threaded into the larger nut. Is it the smaller nut that is loosened to allow coolant to flow through the nipple?

Thanks.

I don't have a 2nd-generation LS, but I can tell you that the driver's side drain on my car is located near where the oxygen sensor plugs in. Have you checked that area?

Radiator drain at bottom of radiator, and engine block drains on both sides of engine block.
