I called my local VW dealer today to see what it would cost to have the dealer change the timing belt in my Jetta and was told $540 ish dollars, not to bad really, but then I asked what it would cost if they changed the water pump at the same time. The new price was roughly $1030 not including a tensioning pulley and i am guessing the serpentine belt will be extra as well. I have looked at Chitty's step by step guide to replacing the timing belt and water pump and both look pretty straight forward. Am I missing something with the water pump? Or is it just the dealer flat rate charge thing hitting me twice for the work to get to the both the water pump and the timing belt?
