Last fall my 92 LT1 was running ar 198-200F. Early this spring it was running around 206F. Since then it has gone up slowly. For the past month it has been running around 220+F. I noticed a tiny leak at the thermostat housing in the spring - but it didn't seen to leak much of anything or leak very often.

Today I changed out the thermostat at a cost of $13 to fix the leak and see if it made any difference, and all I can say is WOW. The car runs at 190F now. I took her for a 10 mile road test, running it up to 80+mph several times and as slow as 25mph. The oil stayed around 208-212F (it has been about 4500 miles since the last oil change, I change at 6000 miles ), the coolant stayed right at 188-194F. This is an improvement of -25 degrees (F) in temperature.
:eek:

If you have not replaced the thermostat in your LT1 and its running over 195F, you may want to consider a quick change out. Be careful, some of the coolant could leak down to the optispark, so have lots of towels on hand to catch it before is can cause damage.

Just so ya know, the stock Tstat for my car is rated at 180F. That's what I replace it with.

Get a fan switch or a reprogram and your car will never top 182*(in 100* weather). My car no longer runs hot.
