In the past few days my escort cos has been runing quite hot. The temp guage normally sits well below the half way mark but just lately its going as high as the 'n' on the norm bit, and stays there for the duratio of the jorney. I have checked all the obvious stuff like coolant levels and oil etc. Anyone got any ideas?

The only things i can add to this are the clutch is slipping and the tappets need sorting, both on my to do list, but i dont think they will have any thing to do with it
