I have a 94 caprice classic ls with an LT1, recently after an optispark and water pump change I had my scanner hooked up while driving back and forth to work. I noticed the coolant temp was 205.4 degrees while cruising 55 to 60 mph. The needle on the dash gauge seemed normal , just below half way. Well after two days of driving and making sure all the air was out of the system I decided to go ahead and replace the thermostat. The old one was maybe two years old 180 degrees and I replaced it with another of the same temp. I tested both in a pan of water and they both performed the same. I put the new one in and blead the system of air over another two days. Now while cruising the pcm says 207 degrees. So my question is, is that the normal operating temp ?
