Managed to get a couple of piccies, although its from the top at the moment.
Its coming from below the part (the one thats rusty) just right and below of the thermostat housing and left and below of the tensioner.
Had a look at some piccies I have found form Ford showing the thermostat housing it does look the right place for the water pump but not sure.
How easy is it to remove the water pump on these, doesn't look much space?
