How often should the coolant be replaced in a 10th-generation Civic?

[StAlina]

The coolant replacement interval for the 10th-generation Civic is every 200,000 kilometers or 10 years for the first replacement, and then every 100,000 kilometers or 5 years thereafter. Method for adding coolant: Turn off the engine and wait for ten minutes: Before replacing the coolant, always wait for 10 minutes after turning off the engine. The coolant can be extremely hot after driving and may cause burns. Lift the car and drain the old fluid: Use a jack to lift the vehicle. Loosen the screw at the bottom of the radiator with a wrench and use a waste fluid pan to catch the old coolant. Wait for the old fluid to drain completely: Remove as much coolant from the engine as possible. Add softened water and let the engine idle for 5 minutes to thoroughly clean the internal cooling system. Add new coolant: Fill with new coolant up to the upper limit. Let the engine idle for 5 minutes, then check the coolant reservoir's level and top it up if necessary.
