Correct Drainage Operation Steps
Step 1: Ensure the engine is cool to avoid scalding from hot coolant.
Step 2: Place a container under the drain plug to collect the old coolant.
Step 3: Loosen the plug slowly (use a wrench matching the plug size) to allow coolant to flow out gradually.
Step 4: After drainage, clean the plug surface, replace the gasket if necessary, and tighten the plug to the manufacturer-specified torque (over-tightening may damage threads or the engine block; under-tightening causes leakage).
