I had what I thought was an overheating issue with my 92 Sonoma. If I drove faster than 45mph (when the trans shifts into overdrive) the temp gauge would climb until it just barely hit the red. If I put the engine under load on the highway, it would continue into the red. As soon as I slowed down to city speed the temp would fall back towards 200F. If I idled it, it would fall back right to 200. During one drive while the gauge said it was piping hot near red zone, I pulled off to a gas station and popped the hood before the gauge had time to drop too far and felt the radiator and the hoses. Everything felt normal, the radiator was cool on the side going to the engine and hot on the side receiving from the engine. Ended up being a loose ground on the back of the drivers side head.

I had the mystery overheating issue. I noticed the car gradually started running hotter. Being super over protective of my car I even took it to two different dealers who looked at it and even then couldn't find anything wrong. I thought I was crazy... thought I was going mad the car was running hotter and only I seemed to be noticing the problem... and then I noticed the car felt like she had less power I didn't know what to think but I kept searching for ghost problems. Changing the waterpump, flushing coolant, new radiator, new cap, new hoses etc. etc. etc. and then one day while leaving the drive thru of a restaurant the car gave me her only clue.
I had one of those riser hoods with the open air vent in the back and all this hot air came out in a burst and fogged up my windshield. Strange I thought... then the car started feeling less powerful over the next few months. Nothing I did seemed to make a difference. It did okay sitting still but when you tried to drive it it started getting hotter and hotter... till one day that wasn't the case. It was summer again by this time and a very hot day. Soon as I'd start the car and get ready to pull off after warming up that needle climbed into the danger zone. I had no choice but to tow it home.
Some weeks later I started slowly tearing the motor apart and there I found the true problem... the ol' #8 gasket leak. I pulled my drain pain and there was the subtle Dannon's Yogurt just laying there. . A headgasket leak none the less but worse it was a stealth headgasket leak that went undetected for almost a year. How could this have been detected earlier? Trace Dye.... do a tracer dye test and see if there's coolant in your oil. If your LT1 is having strange coolant issues after you've fixed the obvious.
