aprox 2 hours - its a real fiddly job - the water pump is outside of the timing chain so no re timing is required, support the left side of the engine from underneath remove the engine mount to gain access to the pump, losen the 3 bolts on the pump pulley, slacken and remove fan belt, remove water pump pulley then pump itelf! when refiting the pump make sure the matiing surfaces are cleaned of all old gasket sealant, use sealant when installing new pump - dont rely on the rubber seal to do its job! - make sure engine mounts are tight after re fitting! - a special torx socket should be used for this job!
