How do you bleed a diesel 1500 CC Peugeot 106 cooling system?

To bleed the cooling system of a diesel 1500 CC Peugeot 106, start by ensuring the engine is cool. Locate the coolant reservoir and remove the cap. Fill the reservoir with a mixture of distilled water and coolant until it reaches the maximum level. Start the engine and let it run until it reaches operating temperature, then rev the engine a few times to help release any trapped air. Finally, recheck the coolant level and top up if necessary before replacing the cap securely.
