Steps to Change the Coolant

- Drain the Old Coolant: Place a drain pan under the water pump. Use a socket wrench to remove the drain bolt from the water pump cover. Allow the old coolant to fully drain into the pan.
- Flush the System (Optional): If the coolant is particularly dirty, consider flushing the system with distilled water. Reinstall the drain bolt, fill the radiator with distilled water, run the engine briefly, then drain again.
- Refill with New Coolant: Reinstall the drain bolt securely. Use a funnel to pour new coolant into the radiator until it reaches the top. Check for any leaks.
- Bleed the System: Start the engine and let it idle for a few minutes. This helps remove air pockets. Check the coolant level and top off if necessary.
