A check of the viscous fan would be beneficial, the newspaper test is a pretty definitive test of whether it is working or not, if it can shred a tightly rolled paper then it's working.
As for bleeding. the best way for the P38 is to take the overflow pipe off the radiator, fill the header tank then squeeze the top hose and plug the overflow with a finger when releasing the hose so it sucks coolant in and blows air out when you squeeze the hose. Keep doing that until coolant comes out of the overflow (it'll take a while and you'll need to top the header up a few times). Then put the pipe back on and carry on only this time plug the hole in the top of the header where the jet of coolant comes back into the header. Eventually, you'll no longer be able to hear bubbles in the system and at that point you know you've got the air out.

Hello and welcome
