Answer
Jim, might as well replace the ECT sensor while you are replacing the thermostat.   Remove the Top timing cover and then you can access the thermostat housing.  You need a torx 40 to remove the screws.  The rest is pretty easy.  Buy a genuine Volvo ECT sensor or you will have problems.  Been there done that.  Roger

Jim, I suggest EBay.  They have all sorts of manuals on Disk or actual hard copies.  Good luck.  Roger
