Hi i am new to this but here goes. My ford Galaxy is X reg 2000 1.9 diesel.The problems i have at the moment are with the power steering and electric fan. First the steering,have replaced belt and had power steering pump bled by my local garage,everything ok for a while then steering became notchy again and started squealing, back to the garage who told me pump was partially seized and they had managed to unseize it, again everything ok for a while but problem is coming back again ,i would point out that car had been standing outside unused for some considerable time, would i just be better off replacing pump?. Electric fan running constantly on start up and a short period after ending journey, temperature gauge gives no reading at all does not move?
