Another overheating thread

The 160 vs 180 argument never ends. Personally, I see little use for a 160 except for the fact that it opens quicker the first time and affords that much more delay (maybe minutes at best) before your temps climb on up to operating temp. If you run a 180 or something closer to the actual operating range of the engine, then the t-stat may have a chance to actually close from time to time, allowing time for the coolant in the radiator to cool further, thus promoting a better "cooling exchange cycle." Then there is the argument that 160 is too cool for an engine to operate. It certainly is for an FE. But in my opinion a 160 t-stat is just a gate that opens once and never closes on most engines, so it doesn't really effect the overall operating temp anyway.

Probably more burping but we'll never know since more than one thing changed. The 16lb cap I have is vented so the coke bottle recovery will not work with it. Not too interested in going back since this is so much of an improvement.

Per the previous I'll probably stick with 160 but go to the high flow.

So you could go run it with the 160 and then another run with the 180 and compare. If it didn't draw the coke bottle contents back in then a recovery system is not the answer. If burping it was the solution you should be able to run with your current t-stat and either radiator cap and be fine. A hi-flow won't matter, IMO.
