Thanks for the reply. Th hole was in the small metal pipe, i looked at it this morning to see how i could patch it, whilst fiddling, i managed to snap the metal pipe (engine end). This actually made my lie easier. All i did was block off the throttle body pipe, and cover the now big hole by pulling the bigger coolant pipe snug up to the engine and secured with two jubilee clamps. I dont know if that made much sense but the leak is sorted, engine staying at good temp and fan is working. I will be replacing the thermostat as the cold start doesnt seem to be working. Progress is slow, but im staying optimistic.
