Replaced mine when I first got the car as it was leaking.5 yrs/40,000 miles later no leaking,but after replacing everything else from the pump forward,trying to fix a problem mentioned elsewhere on here,finally replaced it,160 quid,and problem solved....so far.Make sure you check,unlike me,if it's the 2 pipe or 3 pipe version before travelling 20 miles on a motorbike to bring the wrong one home.Embarressing taking it back to swap!
