Yep, right O birdie, any way back to the think tank task at hand, where to now?
Do we tick the fans off the list and should the temperture switch be investigated? Is there an override switch?
Should the radiator be investigated further however was not the problem there before the radiator was upgraded?
Still thinking head gasket/cracked head?
Aren't cars just soooo much fun ;P
The old rad apparently deteriorated to create the same observations, but supposedly did the job adequately previously.
Hopefully op will get back to us with a revised idea of what his temp gauge's real readings are and whether the fans are switching on in the 95 deg range, which I believe is fine, they should only be there for the 1% of the time when the car isn't moving and it's not that imperative that its operating at its optimum temp while stationary, it's certainly not going to sustain any damage.
Cracked head?, there are no symptoms of oil in water or vice versa, but there was a suggestion of stranger bubbling in rad? Exhaust getting into coolant, there is a test for exhaust gases in the coolant?
Would this perhaps not show up in a cold engine coolant pressure test or perhaps it would seal backup and not reveal itself, the op has not mentioned any coolant loss. Perhaps an engine off hot pressure test, would reveal that, but possibly only cylinder value type pressures (150+ psi)maybe getting through and testing the cooling system to even 20psi may reveal nothing.
Trying a rad of known capabilities would be my first choice but for the op this is probably not an option
