Right lads. my water pump on my UK Turbo is leaking, how much work is involved in replacing one? How long it takes?

 

Bottom hose disconnected/drain coolant.. cam timing chest removed... cambelt removed... waterpump removed.

Makes sense to fit a new cambelt and/or uprated oil pump/front oil seal and/or new thermostat while you're in there. If you don't fit a new oil pump, then re-torque and lock-glue the oil pump's retaining bolts.

When reinstating coolant after refitting everything, do it the 'proper' way so as to bleed the system. Do a search to find out...
