Should i change it

My mk3 has now done 80,000
going back to Austria this year i have bought a new water pump to take with me
nothing wrong with the old one i might add
but does anyone think i should change to the new one before i go
Thanks folks.
Mike.

No but change the cooling system expansion bottle. Expensive but they can crack at that mileage and the temperature guage is too slow to warn you before the engine is toast.

I agree with Drumtochty. I went for this one, not cheap, but a lot less cost than a new engine.
