99 ls1 passenger coolant sender thread?

I am working on an engine conversion with the drivetrain from a 99 ws6, I mounted the sender in the block, in that little threaded bung that sits above the starter. Either it is a poor location to read temperature or the block is still air locked because it is not reading accurate temps. Do you guys know much about this location? I am thinking mounting it in the pass head, near #8 where the plug allready exists. do you guys know the thread this location?
thanks

The threaded water port on the cylinder heads is 12mmX1.5. You didn't mention what gauge/sending unit combo you're trying to use, but if you're going aftermarket I would recommend using an electric gauge vs. a mechanical.
I went with an aftermarket electric water temp gauge to avoid the large temperature probe on most mechanical water temp set ups. I have the electric sending unit installed in the pasenger cylinder head. This required two things; a metric to npt adapter and a shortened electric sending unit due to the small I.d. of the adapter.

Both items can be had for under $20.00 and make this a very simple install.

Its near where the crank sensor bolts to, there is a small bung that threads in that uses an allen drive.
I am allready using the stock sender for the ecu, but for my in car gauge i am using an electric sender, that metric to npt adapter is just what i was looking for.
Thanks for the info guys

That big plug on the side of the block is a block heater plug. I have my sender there. It is a pretty common place to put it with Datsun Z car swaps.
I have checked my stock gauge against more accurate gauges and they track consistently. Since the stock gauge has a total of 3 tick marks on it I couldn't tell you if they are off by even 10°, but IMO who cares. Like I said it goes up and down consistently and does tell me whether I am running hotter than normal.
