Just a small update on this, I put everything back in this morning ready for them to come pick it up tomorrow and i was just reading about removing the belts and the fan.
I was thinking because the fan was all over the show maybe the pump has gone. I went back out and threw a 32mm on it and locked the shaft off and went to undo it and the whole this is moving all over the place which leads me to thinking the bearing has gone.
Do these have a bearing that can be replaced , That's why i think the belt has come off its because the water pump bearing has let go.
Not touching it any more anyway as that's what i pay Lumley insurance for, they can sort it out.
