SERVICE INFORMATION
On 1989 240SX vehicles manufactured within the Engine No. Range, the timing chain guide may have a diminished service life resulting in failure at
relatively low mileage. Should this component fail while the vehicle is in operation, it may cause severe engine damage. Affected vehicle owners have
been notified by letter. A copy of this letter is attached to this bulletin. Affected vehicles in Dealer inventory should be corrected before delivery to the
retail customer! A countermeasure timing chain tensioner and timing chain guide has been developed and should be installed immediately on vehicles
within the applied Engine No. Range. This Technical Bulletin contains an inspection and replacement procedure for these components.
