ive read the previous posts but those problems are either running under normal 40% temp or heating but to not my extent.
How is your coolant level?
I would flush out the coolant and get some new coolant in there, also does your fan come on?

You might have a coolant leak somewhere, if coolant level is fine and your fan doesn't come on then I'd have the fanswitch replaced.
It could also be caused by a thermostat dying/being stuck closed so no coolant will flow through, in which cause you'd need to get the thermostat replaced.
