I've just been out to take some measurements and the top of the fins are 4 cm above the 'Max' marker. Now, looking at the photo, does the coolant level look 3.5 cms below the top of the fins to you? I'd guess it's between 0.5 and 1 cm below meaning that the tank is significantly overfilled.

So your claim that I am "nit-picking" is inaccurate and rather discourteous I have to say.

I'm afraid I didn't take any measurements before taking the photo. But if you don't like mine why don't you post up your own photo? Or write up an official HowTo?

As to the expansion in the header, my own observations and the theoretical figures indicate at least a centimetre tolerance for the maximum cold coolant level. I've stated that many times in coolant threads, along with the photo without it ever being queried. I could go through the maths to justify it, but I won't.

that water you stated under the car, was that coolant coloured or clear water.
If clear and your have the aircon on , it is from the aircon evap unit coming from a pipe under the car.
Re coolant loss , as simon says, need to remove under tray and get under the car and find the red stain.If leaking externally you will see it.Check the V under the manifold for thermostat leak.
Check the radiator top hose connection.
If leaking internally , oil cooler etc , you will have water in oil or oil in water.

That MAX marker is just a rough guide. The engine will work quite happily above or below that marker with no obvious problems.---

Naturally the level changes as the engine goes from hot to cold.---

So stop it you two.-----

Sorry Jon, neither of those two statements is true. The manufacturer's position is that the 'Max' marker is the maximum permitted coolant level when the engine is cold. 'Max' means maximum to allow for expansion without the risk of coolant ejection. The 'Max' marker is significantly below the level stated by T-Cut to be correct. His contradictory claim is therefore open to reasonable challenge, as any scientific theory should be.

Jees - Please, post up your own scientifically correct and carefully measured photo so everyone knows and we can let it drop.

Yes, but not under the MIN mark!

Seems to be alot of variables here, has it been bled properly etc.
If water is in the top tank and then disappearing no matter what level was there its going some where!!!
Hopefully externally !!

Yes it is Pater as Bill tells us in post no. 1:

Sorry Simon but I don't agree with you.

Filling a header tank on a cars cooling system is NOT precision engineering.

If it was then the manufacturers advice to its customers would be---Stay clear of the header tank unless your dash display tells you different.--Play with the levels at your peril.-----
