Extreme Heat Transmission Cooler

[MikeE024]

My results were very different last summer when I drove the TJ without a thermostat between system flushes. While it took the coolant temps longer to warm up, the temps were near enough to normal range when driving on the highway and in general sustained driving.

The radiator fan would drop the temps a bit at times when in idle or putzing along in town, but normal sustained driving would heat the temps back up.

I’m doing a flush right now, so this gave me a chance to share my temps driving through town this evening with the thermostat removed.




Also, I found an interesting take on the cooling conversation (that is well above my head). The thread also mentioned that dwell time is a myth. I’ve seen similar posts but they used the word effectiveness for the temp differential.
