When the head gasket was changed last time was the head skimmed or checked to make sure it wasn't warped? What sort of colour is your coolant and is the level ok? There could be a few causes, it may be worth taking the thermostat out and checking that the water pump impeller hasn't detached from the shaft.

If it's overheating with the engine just idling and with the fans bypassed running continuously then something must be seriously wrong- usually from what I've read with head gasket failure overheating occurs under load at higher speeds, not when idling. Is the coolant definitely circulating? Is there any debris in the coolant? And is it definitely overheating? It's not just a dodgy temperature gauge or sender giving a false readout?

Definitely overheating then! If the head gasket isn't already cooked it definitely will be if you drive it for long like that, and it sounds like it's too far gone for any coolant additive to make a difference- like I say if it's overheating at idle and with fans running continually then you've got a major problem. I'd check the coolant circulation next, if you're happy the water pump and thermostat are doing their job then the only likely causes are a coolant flow that's nearly completely blocked, which if all was running ok before seems hard to believe, or blown head gasket in a major fashion. Before stripping too much down you might want to get a cylinder leak down test done, which should hopefully tell you just how bad it is.

NO! Until diagnosed that's a last resort, if you have poor flow that additive will just block it entirely. A PD engine produces very little heat normally, remove the thermostat and check again

If the restriction in the pipe was blocked then aeration in the system cannot return to the bottle and builds up in the top of the cylinder head.
AS to whether any damage has been done only time will tell, keep a close eye on coolant level for fluctuation also excess pressure in the system and when cold does there still seem to be pressure present when removing cap? if the answer is yes then I think your success may be short lived lets hope for the best :)

As I said I think it will be short lived, you got nothing to lose by trying steel seal.
