it is normal to do the water pump at the same time on evos...........
Just had it alll done today, cam belt kit, balance belt, auxillary belt, air-con belt, air-con tensioner, balance belt tensioner, idler bearing and an oil service.
Keith from AI mentioned that the cam belt should be changed every 3 years or 20,000 miles, is the water pump supposed to be replaced every 3 years/20,000 miles

a pump should last far far longer or is it just that some owners want to replace them regardless of whether there is a problem with it.
Decided to drive the car home as it was such a nice day, had a really nice blast down the A4 and M4, had a smile on my face the entire time

and just fantastic when the turbo kicks, wish i had bought one far sooner
