How do I cure my BMW's overheating?

Hi, I have a BMW 320 Convertible, which had a reconditioned engine with new radiator about eight months ago, but it now keeps losing water! Sometimes I fill it and it will be fine for weeks; other times it empties in days. Now the temperature gauge is shooting straight into the red even when filled up with water.

What do I do?

Hi Leah,

The first things we'd look at are whether the thermostat is stuck closed or the system needs bleeding of air. Please do not drive the car with the temperature gauge in the red for any length of time or you could cause major engine damage.
