VXOC Astra-J/GTC

Hi everyone,

Car overheated on Saturday, checked coolant level and nothing remaining in reservoir. Topped it up and made it home. Not easy to see where the leak is coming from, I think it may be the water pump, which I believe is a known issue on these cars. 

Taking it to a garage tomorrow. If is a water pump, what work would usually be completed additional to the pump replacement. Timing belt? Tensioners? 

Whats a reasonable price for water replacement?

Cheers

Not sure if the pump is driven off the cambelt, but if the water pump is driven off the cam belt then yes do cam belt tensioners might as well do the aux belt to as it has to come off in the process.
