What is the solution for slight coolant leakage after replacing the cylinder head gasket?

[Stone]

Coolant leakage should be addressed by replacing the hose or re-securing the connection depending on the situation. Coolant replacement method: Drain the old coolant, then flush the liquid channels with clean water. Add clean water to the coolant reservoir, then continue adding water to the reservoir so that it continuously flows through the engine cooling system. Start the engine and let it idle for 3 to 5 minutes to circulate the water. The water initially flowing out from the reservoir will have a faint pink color. Continue adding clean water until the outflowing water runs clear. Note: Don't forget to remove the heater hose to drain the water from the heater core. After approximately 1 hour of draining, add new coolant through the radiator hose - this allows the coolant to flow into the radiator quickly. Then add another container of coolant to the reservoir until it's nearly full. Run the engine for about 10 minutes; as some air is purged from the cooling system, the fluid level will drop. Add more coolant until it reaches the "MAXT" mark on the reservoir.
