Engine Overheating problem

Kobus (mechanic) came to my house on Wednesday and identified the problem as a hole in the water pump. A new part was purchased and fitted by Kobus, and although I thought I still had a problem when I started the car on Thursday morning, Kobus came again to my house and confirmed that the problem was an airlock in the cooling system. I drove the car a lot today (Friday) and the engine remained cool. I am a happy client.
