How do you top up the engine coolant in a peugeot 307?

To top up the engine coolant in a Peugeot 307, first ensure the engine is cool and locate the coolant reservoir, typically marked with a blue cap. Open the cap and add the appropriate type of coolant mixed with water, if necessary, until it reaches the "MAX" level on the reservoir. Be careful not to overfill, and securely close the cap when finished. It's advisable to check the owner's manual for specific coolant specifications and recommendations.
