I noticed this while washing out my engine bay just now, and I am shocked that there isn’t a system prompt when it gets close to the minimum operating level. I assume this is because my exhaust gas heat exchanger has a leak, given how many posts there are about that issue already. hybrid cooling Loop seems to be running normally. How is there a notification pushed to my phone when the washer fluid res is low, but not the main cooling system? Doesn’t make sense, but this is unacceptable on a truck with 24 k miles.
