Totyota Previa losing water

[Tigress]

I have a Toyota Previa, and 2 months ago the radiator burst, leaving me with a 2 hour wait to be rescued by the RAC. Anyway, I had the thing fixed, and all was going fine until last week when the thing started to lose water again. I thought that the head gasket might be on the way out, but apart from the water loss, there's no other obvious sign to me, I just can't think of anything else, unless there's a cracked pipe or something. I don't know, what d'ya think?

If there are no signs of water leaks, and no sign of water entering the sump. (Your oil will have a white froth in it ).
Then you may have a tiny leak in one of your hoses.
This will not show up until the engine temperature is high enough to cause pressure, thus forcing water through a leak that doesn't show when the engine is cold.
The solution, Park car, Run engine until normal temperature is reached, Then check for any water leakage.
WARNING!!! DO NOT REMOVE RADIATOR CAP WHEN ENGINE IS HOT.
Hope this helps.

This sounds very likely, as the radiator water is very clear with no signs of residue or oil in it. Ok, well I shall do what you suggested this afternoon, and hopefully the mystery will be solved. Thanks very much bird!!
