Ive just taken my series 2 turbo to my mates garage in chertsey as its been over heating and just as i got there theres this huge ssssssssss noise i couldnt find where it was coming from, it sounded like the block

the hose underneath the top boost hose has split plus my water bottle is about to burst

so my question is what other damage have i done ? and if anyone in surrey has the hoses i need and a water bottle i can collect either tonight or tomorrow morning then please please let me know.
Thanks
a very unhappy sam
