When your have been driving and the engine is hot, stop the car and check your resevoir. It should be at the max level. When the engine is cold, the level should be about 1cm below maximum.

just buy new coolant and do a whole system flush. not worth the 40 bux putting your motor at risk of overheating etc

Honda All Season Antifreeze/Coolant Type 2 (P/N OL999-9001)

His car is a 2008 Civic. No point changing coolant.

I've seen a quite a few Honda engines with corrosion from using wrong coolant. Having said that, many aftermarket coolants being sold today are compatible with Honda's coolant, unlike 10 years ago.

Also, if you already have Honda coolant in there and don't need to flush, then you're better off using Honda coolant to top up and not use a different brand. If you want to drain all the coolant, feel free to use another brand. Just choose the correct type to avoid water pump corrosion.
