Update:

Jamsport found that my water pump is leaking anti-freeze onto my belt so that's why it's been squeaking!
But that's not all of it! Ford the f'ing fraudsters said they couldn't find a leak when I took it to them last month but I asked them to fit a new pump anyway! Lazy *********
Getting a new pump fitted at a local garage tomorrow I hope and never trusting /fraud AGAIN!
