I don't know, but is sounds like two problems. Number 1 your radiator cap is to stiff. Do you have the right radiator cap on??(meaning each radiator cap has different temp points) or your clutch fan is too weak. (Wait until your car is warm, before you have someone start the car for you. Hold the clutch fan. If it grabs your in business, but of it dosen't you clutch fan is too weak. Had the same problem a few years back. The radiator was fine, the water pump was fine, the thermostat was fine, which only left me with one thing. The clutch fan!! Unless your timing is way out LOL. Some original photos have not been recovered yet.

Sound like radiator cap spring or seal has failed and it's not holding the 15psi of pressure it's supposed to.

let it heat up with cap off put a funnel at where the cap goes and tape it up so it doesnt leak once warm rev it and look for bubbles then bang youve got a blown headgasket if not and still getting hot pull your thermosat out and get your kettle and boil it and drop it in it should open if not change it. if it opens then go to your cap then possible blocked radiator flush it then change it then if still bad headgasket. hope its in order but there your possabilities

blocked radiator, shagged water pump, thermostat, cap or clutch fan. put a cut thermostat in it to make it run cooler. Cut the two fins of the thermostat at the central mechanism and put the cut unit back in, itll restrict the flow enough to cool it down but still let it flow nicely. Take the radiator out and reverse flush it with the hose (it can still have water running in and out freely and still have a blocked core, very deceitful) New coolant and make sure the clutch fan is good, had the same problem on mine.
