One of the most common problems Renault Megane 2 owners face is engine overheating. A rising temperature gauge or steam from the radiator is a serious warning sign.

Main Causes

• Faulty thermostat – Prevents coolant from circulating properly.
• Clogged radiator – Reduces coolant flow.
• Water pump failure – Coolant circulation is disrupted.
• Cooling fan not engaging – Electrical fault or bad fan switch.
• Blown head gasket – One of the most severe issues.

Solutions

• Check coolant and antifreeze level regularly.
• Replace thermostat and fan switch if faulty.
• Have the radiator cleaned or replaced if blocked.
• If a blown head gasket is suspected, stop driving and see a mechanic immediately.
