I may be one of the few folks that have had some close encounters with overheating.
Discussion Link.
The Integra has a rad-block during the coldest 1/3 of the year, but if outside temps get above 50F, I've seen coolant temps as high as 240F, so I had to remove it for the rest of the year. KC temps range from -1F to 101F, so seasonal adjustments have become a tradition.
Timing is at max advance, Stat = 190F; Fuel = 91 Octane, intake temp target = 100F, hood gaps sealed, radiator replaced 3 years and about 40,000 miles ago, Water/Coolant = 70/30.
I think the automatic transmission is partly to blame fr the heat build up. I notice the coolant temp rise in the following situations: mostly at highway speeds/RPMs, and secondly during stop and go traffic (especially with the A/C operational).
The solution has been to run a higher concentration of water-to-coolant, and check the level more often. I also opened a panel in the wiper area to allow more airflow across the engine during Summer.
To get ready for Winter, I'll probably have to increase the coolant ratio to prevent freeze-up.
