I have a 2003 chev blazer that I have swapped a vw tdi engine into, mated to the nv3500 5 spd manual. Due to clearance issues I deleted the belt driven vw power steering pump, and am running a volvo electric power steering pump from I believe a 2006 v50. While picking up oils in canadian tire I could find power steering fluids rated for gm or volvo, but not one that was rated for both. What would the experts here recommend, running the gm fluid to suit the gm steering box, or the volvo fluid to suit the volvo pump?
