How to Replace the Coolant in a Skoda Rapid?

[StNorah]

Here are the steps to replace the coolant in a Skoda Rapid: 1. Before replacement, ensure the engine is cooled down. Do not perform the replacement immediately after turning off the engine as the hot fluid can be dangerous. 2. Before replacing the coolant, place a bucket under the engine to catch the old coolant, then loosen the screw to drain it. 3. Tighten the screw, remove the screw from the coolant reservoir, and fill the reservoir with new coolant until it reaches the full mark. It's okay if it slightly exceeds the mark as some will be consumed over time. Generally, it is recommended to replace the coolant every 30,000 kilometers. Detailed replacement steps (for reference only): 1. Unscrew the radiator cap, open the radiator drain valve, and drain the coolant. 2. Insert a rubber hose connected to a tap into the radiator filler port, turn on the tap to allow tap water to continuously flow through the engine cooling system. During this flushing process, keep the engine idling and continue until clear water flows out of the radiator. 3. Turn off the tap, wait until all water in the cooling system is drained, then close the radiator drain valve. 4. Add coolant into the radiator filler port until the radiator is full. Unscrew the reservoir cap, add coolant up to the "Max" mark, being careful not to exceed it. 5. Replace and tighten the radiator cap and reservoir cap. Start the engine and let it idle for 2-3 minutes, then open the radiator cap. As some air is expelled from the cooling system, the coolant level will drop. Add more coolant until it reaches the "Max" mark again.
