Hi, I had this problem with my 1995 LT1.
I tried everything you did and more. Finally, I found a guy that everyone here is talking about. He was a GM dealer machanic for 30 + years. He took it in and found it was the head gaskets afterall. Others told me that it wasn't and it had passed the pressure tests etc. I came so close to giving up on this love and this guy saved the day. Trust me and him, it is almost guarenteed to be the headgaskets. I could have saved myself a lot of expence and fustration if I just went straight to this. But heck, why not change the water pump and thermostate anyway while your at it for what it's worth.
Best Regards

I purchased my Torch Red 96 LT1 in August of 2007 (after selling my 84) and never had an issue until recently. This experience has become increasingly frustrating as my Vette is currently my DD.
Some days the car runs perfect. I drove over 100 miles from San Diego to Los Angeles with the engine temp floating around 200.
As I pulled into Burbank the engine temp shot up from 200 to past 260 in a matter of Seconds. I let the car sit for 15 minutes, started it back up and it was like nothing ever happened. The "Low Coolant" light comes on, however the reservoir is almost full and bubbling like crazy. Overheats are completely sporadic. There is no oil visible in the coolant. The fans come on automatically at 230.
Things I have done over the past week (None of which fixed it)
1. Replaced the water pump.
2. Had the system professionally bled and flushed. (Multiple times)
3. Replaced the 160 thermostat.
4. Replaced the radiator cap with a 16psi.
When the engine is not overheating the car runs very strong which leads me to believe it is not a head gasket issue.
Any advice from the Vette experts?
