Hello James and I'm sorry to hear that you have two problems at once with your ZT KV6.
I'll begin with my number one tip ...

Don't guess!
In fact, I'd say it's extremely unlikely to be the water pump. Actually they are very reliable and durable. We frequently hear of precautionary water pump changes during cam belt renewal but that's only because it's such a major job to do later. It doesn't mean that the pump
is going to fail. Come to think of it, how many failures do we read about? Umm .... errr ..... hmmmm .....
The sign of a faulty water pump is a slow drip of coolant at the front plate of the engine at and above the oil filter canister. This doesn't match your description. Water pump problems result from a worn bearing (very high mileage, well above 100,000) or a damaged seal (poor repair technique) or replacement with an inferior aftermarket part.

Be careful James. Coolant leaks on K series engines are frequently misdiagnosed involving huge and unnecessary repair bills. Only in November I saved a cherished 2.5 litre faced with the threat of head gasket replacement or even a new engine
when all it needed was a bit of TLC and parts costing £8.
Take heed of Andy's tip (
trikey) and note his location.
You may like to forget about the local mechanic idea for now.
