 I am currently having to top up radiator with about 1 ltr of fluid every 50 miles or so. There are no signs of coolant leaks under the bonnet or on the ground when standing.Also no evidence of head gasket issues.Car is not overheating, and heater works fine ( apart from control valve being stuck in open position ! )
I am wondering if the water is being blown from the radiator cap? Although this looks fairy new , pictures of radiator caps I,ve seen for the cars indicate it could be for a series 1 and not a 2/3. Does anybody know if pressure ratings are different  for different series cars? Could this be my issue or are there any other suggestions to help me out ?

Fulvias do not need the header tank full. They self level. So long as there is c 1/2" of antifreeze above the rad matrix and this remain stable then it is ok. Dont change the cap for a high pressure one.. Can't remember but think 1/2bar is correct.

Just checked and can confirm 0.5bar cap on my S2 radiator.

The coolant consumption you report is quite large and not normal at all. Assuming that you don't have a pool of coolant leaking from the heater matrix/valve and hiding under your carpets, regrettably the first explanation for your problem is that the cylinder head gasket is damaged somewhere. I suggest you do a cylinder compression test to find out this possibility. The 0.5 bar rating of the rad cap is correct. Andrea

Thanks Guys. Car is currently in paint shop having work done for next few days. When I get it back Ill check the cap rating.
Head Gasket failing will be my next port of call. Interestingly the engine has started to puff a bit blue smoke( not white) Undecided from exhaust when pulling away. Engine is performing fine and has no nasty knocks and good oil pressure.
Thought this may be due to valve stem seals letting oil by, as car has recently been recommisioned after a long lay up. However could it be another symptom of head gasket giving up?

Smoke could be a mixture of oil and coolant in the exahust ports. Hopefully this is not the case but it deserves investigation. Moreover, the valve stem seals (especially the old type ones) do wear out giving a puff of blue smoke when starting and when lifting the throttle. Modern seals are much more long lasting. The guides could also be worn. However, these potental problems will not give just high coolant consumption. Andrea

I agree with Tim,
I don't think you're losing it, my 2c has only ever settled just above the Matrix, I did the filling up every morning on my way to Portugal one year, then wondering where it had gone the next morning.
Eventually came to the conclusion that it was blowing it out of the overflow and finding its own level, 16 years on its still the same.
Series 1's don't have the seals anyway, 20 years and 36,000 miles later I get a bit of blue smoke!
But what I burn is negligible.

I agree with Brian, same with a Flaminia, I used to top it up until I realised that this how it was before expansion tanks.

 Radiator cap proved to be ok. Coolant seems to be holding its own for now. Wondering now if it is me topping up when car is parked on a slope and also if there have been air locks in the system as the temp gauge is registering intermittently . Still dont think it is ahead gasket issue. As the heater valve needs replacing I now plan to drain and flush the system and do a general overhaul. to make sure everything is working as it should.
The puffs of blue smoke are almost certainly down to worn valve stem seals. Another little job to add to to the list. Oh the joys of old Lancia ownership!
