Surely if it was a blocked radiator the boiling would occur when the engine is working i.e. a drive on the motorway.davieboy said:could, among other things, be a partially blocked radiator.
still don't know what was wrong with the old engine.......
only asked 12 days ago, possibly could be a related problem.
The engine wasn't overheating, according to the OP.empip said:Electric cooling fan? Is it actually working correctly?
It will be the one on the expansion bottle.shorn said:Other than that I have a plastic cap on teh reserve tank, but that is not really a sealed one or anything like that.
Thanks!

Or maybe someone replaced the pressure cap on the expansion bottle with a plastic one? Difficult, don't know the full history or the underbonnet layout of this vehicle.Softus said:johnb80 said:It will be the one on the expansion bottle.shorn said:Other than that I have a plastic cap on teh reserve tank, but that is not really a sealed one or anything like that.

Apologies to johnb80 for this, but I think it's the radiator cap.
My error was forgetting that some cars have both rad cap and expansion vessel. If water is regularly escaping into the expansion via the little tube on the boss where the rad caps fits, then the rad cap is faulty.
You need to get the correct cap - the main dealer isn't necessarily the only place to get one, but you'd more certain of getting the correct part.
