Engine Coolant
 

Hello,
I have 2002 Honda Civic, and I am wondering how often does Engine Coolant needs to be replaced? 30K, 60K, 90K, 110K?
Thanks!

umm I think like 60,000 miles but don't quote me on that, check a haynes manual. I think it depends on the buildup of carbon in the system which can vary on environment and driving. Usually if it's at a certain level it's wise to do a coolant flush and then fill it back up.

Replacements should also be based on time as well as mileage, with 5 years at the longest. If it's still the original that came with the car, it is due.
