I've had my '05 GT for 14 years and 35,000 miles. All of the service has been done by my local and delivering Ford dealer as per the maintenance manual. Does any member have any information about when to replace the coolant hoses?
I've never changed any coolant hoses on any car except on condition. If it's cracked or bulging, then replace. Even then, you can go a long time before it fails completely.
