SERVICE ACTION
Owners of affected vehicles are being notified that Ford Motor Company is providing additional coverage for the affected engine camshaft chain tensioner and lower intake manifold gaskets.
If either the camshaft chain tensioner or lower intake manifold gasket should require replacement, dealers are instructed to install both of these upgraded parts at the same time, at no charge to the customer.
The no charge coverage for this condition is available for 6 years or 72,000 miles from the vehicle's warranty start date, whichever occurs first, and will automatically transfer to subsequent owners. If the vehicle already has more than 72,000 miles, this coverage will last until April 30, 2001.
REASONS FOR THIS PROGRAM
[Ford Motor Company has] incorporated enhancements into newly produced Explorer 4.0L SOHC engines. The long-term benefits of these improvements are being offered to prior customers.
The need to install a replacement camshaft chain tensioner is typically indicated by an engine rattling noise that occurs just after cold engine start up and goes away within a few minutes after the engine is running. Rough idle and low idle are symptoms which may, in some cases, indicate an intake manifold leak.
The condition of either or both of these components will not cause engine damage or failure, but may decrease the customer's satisfaction with their vehicle.
This is the only bulletin I could find...hope this answers your questions.
