Irratic kooling temps
This Thread is about 92 C4 that's having Irratic cooling temps but both digital and analog readings do match when the heat goes up or down
I picked up a thermostat and was going to change it thinking it would be a cheap fix at first but am having 2nd thoughts being I donot wanna take a chance on water dripping on the opti!!!!!even with rags wrapped around the thermo housing
Maybe changing the coolant and thermo might fix the problem but am not sure and thinking if anything needs to be changed or drained will let the shop do it so if anything does happen to the opti theyd be responsible. Anyway am looking for solutions other than shop time in an actual shop but might have to go that route

Burp the air out and take the top of the shroud off and clean it out.

You haven't mentioned the fans running appropriately but you "hint" maybe they are when you mention temps rise/fall. Clearing the cooling/refrigeration module is to be considered maintenance. You haven't mentioned the temps either so .....
Why would you suspect the t'stat? Something you haven't shared?

I'd think it very difficult to try and hang a shop out there for an opti- failure eve if it occurred shortly after the t'stat change. Very difficult!

Can you give more information...temps, driving conditions, etc.
BTW, the thermostat is probably the easiest thing to change on the LT1. I recently changed it on my 95 and barely spilled a drop. I did tuck rags below it just in case. I removed the cover with the upper hose still connected.

When I had my 95, I too was afraid of the Opti so I drained some of the antifreeze in a bucket ( just to make sure) it was very easy. My 95 had a burping screw which simplified things.

I would check the Coolant temp sensor. It lives on the front of the water pump and is obvious as its the only electrical connector. It It could be giving bad readings.. Don't unthread it as coolant will run out, maybe just a test with a OHM meter to start. If its bad then you will have to draint he coolant anyway and you can change the sensor and thermostat all at once.
Also make sure the radiator is clean and free of obstruction. Look from underneath.

also if the shop did do something to have water drip on the opti your damn right theyd be responsible being it would seem awful funny the opti dying right after it had been in the shop when its never given me any trouble and was just replaced along with the water pump in 2014

Might just have sucked a plastic bag up inbetween since it was sudden. You must take the top shroud off to see. Or sneak a camera in there.

Sounds like the thermostat is cycling. Temps are not getting high enough for the fans to come on...unless you are running a/c at the time. My car cycles about the same (95 M6), but since that is a sudden change, you might want do do as Antfarmer said and inspect the front of the radiator for blockage.

You might as well put that idea right out of your mind before you hire anyone to do anything to your car. You should discuss the opti issue with them if your worried about it. You will never impose this responsibility upon your mechanic and neither will your attorney. Thinking you can is pure fantasy. Don't set yourself up for unnecessary grief.
