To lower the wear on your engine, the literature is clear -- have everything run at around 185 degrees or so. If you drive your Cobra for an hour, and the engine coolant gauge and the oil temperature gauge both read 185, then that's about as perfect as you're going to get. And if you have any doubts at all, use a vacuum pump and pull a sample of oil out of your pan and ship it off to the oil lab for an analysis. An analysis will tell you if you have any moisture or contaminants in there.
Thanks for your response.

She's running about 180 coolant and as stated about 220 after warming up, weather it's 35F or 75F best ambient this year so far...

Before the t stat it would over cool and never reach more than about 140-150F...

I wonder if the guts in the canton Tstat are adjustable or replaceable?
