A massive thanks to Julian,
On the way home from JAE I had to pull over to the hard shoulder on the M1, the car overheated. I knew he was a few miles behind me towing his caravan. He went out of his way to get me some water so that I could get on my merry way.
Looking at the issue I think the fan is buggered as it wasnt rotating fast at all, along with the front mount restricting the airflow and the heat of the day conbined in my breakdown.
anyway thanks again matey
Steve
