Hello Have a 2002 Volvo V40 2L Turbo with 163hp. In the cold state you can hear the hydro-pump cores, but then give up after a short time. Think that these are finished. Where can I find the suitable ones? Skandix offers nothing. Do I need to change the shocks special tool, or do the camshafts have to be out? I’m from the compartment but my active screwdriver time is already something… Thank you very much..
