Having the radiator rodded is a good move. Retest. If it has an electric radiator fan check temp sensors. If the fan has a clutch it may need to be replaced if its slipping with the engine hot. Check bellts. Its likely a fan air flow issue if the engine overheats when the care is not moving or is moving slowly. If the engine overheats only with AC on that narrows it down. Write back if that's the case. Lots of things can cause this. Antifreeze and a good radiator cap discourages boiling. Pressure in the radiator raises the boiling point but it can't build up pressure if the cap is bad. Antifreeze also raises the boiling point. If actual boiling happens in the engine then steam builds up in critical places and drives the collant out of the block making the engine even hotter than it already is. Replace the cap. Check the antifreeze.

Dipstick, oil filler , filter etc are under the passengers front seat.
If you lift the carpet immediately in front of the seat, you will see a pair of clips holding down the seat, unlatch them and lift the seat ( in some models they hide a clip in the centre console).
The brake fluid is under a cover in the dash.

hi the problem you are having could be down to a few problems, now the first thing i would try is the thermostat you can remove this and place it in boiling water to test if it opens up or not if it dont open up the getting this replaced should solve your problem.
now another thing that could be causing you problems is going to be the water pump now if the bearing has gone it wont be pumping the water properly and this can cause the engine to over heat, it can also over heat if the water pump is leaking and letting in air as the air would cause an air lock and the water would not circulate around the cooling system properly.
you should be able to test the thermostat by trying the heater in the car if you get the engine warm then turn the heater on to hot if the air comes out cold then this indicates the thermostat is stuck in closed possition.
your problem could also be water leak so check your coolant level and see if you are losing any water.
another cause could be that your fan is not cutting in when it should you can test this by leaving your car parked up with the engine running and then when the temp reaches near the red or top of the gauge the fan should cut in and then this should cool the coolant and bring the temp down.
I know you say you have had the head gasket checked but check the oil for signs of water take out he oil level stick and check for signs of a whitish liquid like mayonaise if this is present then this points towards head gasket failure.
I hope i have given you some things to check and look for, you should find your problem if you check the things i have told you, if your fan dont cut in then you need to replace the switch that powers the fan so if you follow the wires from the fan they will go to a switch on the engine's coolant system so if your engine boils up before the fan cuts in then this switch will need replacing.
please bare in mind that the engine over heating can cause the head gasket to fail and even worse it can crack the head, so you need to find the fault as soon as you can to prevent further damage being done to your engine
