Changed out the T-stat for another stock 2014-18 unit. Also repaired a pinhole exhaust leak. Buttoned it all back up and pedaled home - the stock temp gauge was spiking hard and would drop occasionally - not what I wanted to see. I hooked up the Torque app and it noted the temp was sitting calmly at 200°, calmer than I was.
Further thought noted I used a 1983 temp sender as it has an integral ground. Evidently it doe NOT use the same resistance value as the 1964-77 Pontiac sender. Mnnh.
So I ordered a TS6 and connector and will change the harness. The billet adapter will need to be retapped for the 1/2-18 NPT sender.
The speedo cable is also twitchy - this damn thing is brand new! I gather they are not lubed from the factory? I tried to pull out the cable portion from the trans end but something is hanging up...
