    Coolant level change for a milage.

    I'm curious about coolant level decries for a milage. I got max to min level for about 11K km (6.8K miles). And I don't see any leakage. What is your experience?

    Coolant additives that improve heat transference

    In my C7 Corvette I run this stuff https://www.amazon.com/Red-Line-80204-Water-Wetter/dp/B000CPI5ZK to improve the heat transference from the coolant to the radiator and it works wonders, typically coolant temperatures are 10F+ lower than what they used to be without the additive, I also use it...
