So, I had my 2007 Acura TSX serviced at my local Honda dealership a few weeks ago. At the time of service, my maintenance minder called for a coolant flush (100k miles). I did that service, and noticed today that my overflow reservoir coolant level is sitting at the minimum level line when the engine is cold. I was going to stop by Honda and see if they would top this off for me. However, I was just wondering if it’s ok to be driving around at the min level long-term.
