whats the differance between series1 and series 2 water pumps? is it series 1 has 2 hoses going to it and a series2 just has the 1 hose?
only reason I ask is my cars supposed to have a series 1 engine, and I want to make sure I order the correct pump, mine has 1 hose going to it,

My car started out as a mk4 1600i

cheers
