Drained radiator, replace hoses, fill surge tank. Vent some air through radiator vent screw top of radiator passenger side. I put cap back on tank, run at 2500 rpm for a few minutes, heat works fine, gauge is centered on dash, display reads 195? I think, all good I think. Next day I check tank a little bit low, so I remove cap, hear a slight hiss, pressure relieving I believe, top up tank replace cap. Go for a ride around the block and the needle goes up to almost red zone, display reads like 250. Park it, try bleeding radiator again, seems okay. Squeeze both hoses in and out of radiator, trying to work out air, gauge reads 270 now, engine off for five hours now, seems like engine is air bound. I cannot get it out, pulled his to heater core that has coolant in it, will wait overnight and try after work tomorrow maybe everything will settle overnight. Will start fresh tomorrow, any ideas? What to do now? Does surge tank need to be completely full up to black line in your pictures? Above the small hose coming back to tank? If it was below that could I be letting more air in? Need some help please? Thanks

Just to update; what I did to bleed was fine, just a freak thing. While I loosened cap evidently the temperature sensor in the lower section of thermostat housing went bad. Just a coincidence, replaced sensor and all good.
