For those that aren't on Facebook I came across an issue with a coolant hose. The hose fits into the top of the expansion bottle. Its made from plastic and became hard and brittle only noticed issue when I was loosing coolant slowly like 500ml over a 2 month period. As it was going for a service I asked them to find out where the leak was. My wife took the car in service was completed, they had located the leak and the part was going to take 5 days to arrive. The wife drove home just round the corner from the house steam everywhere. So I contacted garage to find out which pipe, asked them for the part number. I then rang another dealership I was told we will have it for you latter this afternoon. 15.00 and the part is on the shelf I fitted it in under five minutes. So if anyone has the same pipe as mine I suggest you get it changed I will attach pictures of original pipe and new part number. The new pipe is all rubber no plastic

I cannot believe how near we were at the weekend to an engine failure on this very same issue. As luck would have it we were putting a parking ticket on the dash of our car when we heard a whoosh/pop noise. Looked under the car and noticed coolant dripping from the under tray. It was the exact problem that the OP had.
( Another 10 seconds and we would have put the ticket in the window,locked the car and gone shopping only to come back oblivious to the fact our car was about to overheat and possibly seize without us knowing due to a major coolant leak.)

The old design of pipe is just ridiculous,a brittle plastic section coupled with a rubber piece. It was always going to fail at the connection!

As mentioned the new  part is now all made of rubber with a solid clamp at the coolant tank end, and is easily fitted in under 5 minutes. I do however believe that Ford should be recalling all owners with this old crappy design of overflow hose fitted to there cars and replace FOC before there is a wave of claims for engine/turbo failures.

Like the OP we have a 1.6 Ecoboost, ( in150 BHP guise ) engine in our Mk3 so am not sure if it affects all petrol models or even some diesels, but please check yours out before it's too late.

Another heads up guy's.
We have been losing a small amount of coolant from our 1.6 ecoboost over the last few weeks. Changed the expansion bottle cap as I thought that maybe the pressure valve maybe duff. This seemed to improve the situation but not resolve it completely. So today I lifted off the expansion bottle and found that it had some hairline cracks and a small bulge on the underside.
Will be fitting a new one on Monday and will post a picture of the old cracked one for reference.

i know this is an old thread, but as photobucket is not working on here, do you still have the part numbers for the hose and tank?

Well guys, car has been in the shop for just over a day, when leaving the house yesterday morning, i saw a few drops of oil on the road where i park it so rang the garage to ask them to check it over for an oil leak, as i am not the only who parks outside my house,(which is something that really p's me off) turns out its got a cracked head, but is covered by the recall so thats a plus, just waiting now for them to get a new one in stock for me, stay tuned to see how it all goes.
