What radiator options??

Have you considered the switch/gauge being faulty. My old neighbours charade was overheating, he tried everything and finally replaced the switch and that was causing all the issues (the car was never really overheating). His car also overheated when driving on the highway though

Also what are people talking about not diluting your coolant and diluting it...

You get 2 types of coolant, ready mix (which you don't dilute) such as OEM and others and then you get concentrate (which you have to dilute)

By switch are you referring to the one which controls the thermo fan, if so this is working, as I just tested now, it opens up and turns off like any other car.

Update.

Have purchased thermostat, will be installing it tomorrow, I am also considering replacing the top and bottom radiator hoses.

Also I need a new thermo fan as mine just f****n broke which I just replaced it 2 weeks ago for $65!!

So now hopefully I will see if the water pump is working by when I change my thermostat. If water pump is fine and new thermo goes in and it still overheats I will be taking it to my mechanic/tuner to get that test which detects the presence of exhaust gases in the coolant to determine if I have blown my headgasket.

Should a frustrating couple of days, YAY! :@

Yes, one of these switches is temp switch. How did you test it?
Put it in hot water? and check that the switch was "on"?

Then there is the gauge temp sending unit. This is what may also be stuffed.

I'm stopped overheating with the following changed

Motl 15-50 (was using Edge 5-30)
Castrol mixed 20-30% (was using Honda OEM)

Not one overheat since!
