02 Civic SiR. I just noticed the coolant is about an inch below the "low" mark on the reservoir. There are no operational problems, runs normally, doesn't overheat. Is this low enough to have caused any damage?
I don't have any extra on hand, but it's booked into the shop tomorrow morning for an unrelated maintenance item, so I'll ask them to top it up. The manual is very specific about using a particular Honda brand coolant. This is just an independent shop (no Honda dealer in town), so I have no idea if they'll have it in stock.
