Default 2006 Expert. Cooling Water disappearing

Van constantly requires topping up with water and yet there is NO visible sign of a leak.
I can top it up and within about 10 minutes the level has dropped. There is no evidence at all that the water is leaking out. This has been happening for the last couple of months but the other day during a Motorway run, the STOP light started to flash. The vehicle has been recovered but will not start now.

The cap on the expansion tank appears to be just a Brake Master Cylinder cap.
I am assuming that this has been fitted by someone in place of the original.

There is no pressure release spring in this cap so presumably the pressure can just rise and rise.

Or is the pressure release spring somewhere else in the system.

2006 should be older type is this correct ?

If so relief valve is built into cap it has probably fallen out

If its not starting you may have overheated it did you ?

I am not familiar enough with the van to know whether it is the older type or not. It may have overheated, given the circumstances of the STOP flashing and then no water in the expansion tank. Would this mean that something else is damaged.

On the cap, the mechanism has not fallen out. I think it more likely that someone previously has replaced the cap with the wrong type. I must admit, I was surprised that the Brake Master Cylinder and the Expansion Tank Cap, have the same thread and therefore could be interchanged.

It may be worth mentioning that the Oil Level is normal and looks good, ie there is no trace of the mushy appearance that normally suggests that there is water in the oil.

A head gasket can (blow) In many ways the gasket can leak coolant into the cylinders which then burns off (steamy exhaust) What has it used as coolant It should not be plain water this alone can erode gaskets if used over a prolonged period ,If the coolant jacket passes through the Inlet manifold it could be leaking coolant into the Inlet Manifold get a garage to do a sniffer test which tests for leaks of combustion gases into the coolant system If they can get it started

@Jagn
Thank you, a sniffer test sounds a good idea but at the moment, the van will not start.

Do you have any views on where the water is actually going when the level can drop very significantly over a period of 10 minutes or so.

Incidentally, does anyone know the coolant capacity of this vehicle.

I am a little disappointed that my 3 threads were merged.
They were different topics with a title relevant to each.

This applies especially to my request for details of a Workshop Manual and the overall title above is probably unlikely to be of any help in locating anyone who can help me with the Workshop Manual question.
