I have checked all the hoses are connected..... its a TD5....... it has this other hole on the bottom..... there is the 2 pipes on the top the pipe on the side and a pipe on the bottom..... and this extra hole wich goes up into the resoviour for over an inch and a bit..... go out to your discoverys and have a look under it there is a moulded hole... its not on any diagram and its so hard to find a picture of the bottom of the resoviour haha so i dont know if its normal or not??? but even so the problem was never there untill this weekend also there is no pressure in any of the cooling system hoses?
