I have done a lot of work on my cooling system...
New hoses, new seals on logs, new water pump, (all from Murph), also replaced cap and temp sender and radiator switch rigged switch to allow me to turn fan on. Ugh! All this in the last 6 months. Now I noticed that the upper radiator hose had collapsed after a short ride. I removed radiator cap and it sprang back to position. Could I have air in the system. I did just fill it up couple of days ago.
I followed the shop procedure I think? Filled radiator with water pump bleed screw out until fluid exited water pump installed screw then filled it until it exited at thermostat bleed port, closed bleeder. Then filled it to top of radiator neck... I am not sure where to go next. Sympoms of bad radiator cap or air in system? Any ideas?
