Some 2008 Focus models built up to Oct. 31, 2007, may develop a small leak at the upper radiator hose. According to Ford Motor Co., one likely cause of the leakage is small cracks in the plastic hose clamp. The cracks result in the clamp stretching and losing tension, which in turn leads to pressurized coolant leaking between the upper hose and radiator fitting.
Removing the plastic clamp and replacing it with a conventional steel worm-drive clamp should eliminate further leakage issues.
