Service Update
18209 Diesel Turbo Exhaust Leak

This service update should be performed on vehicles in dealer inventory only. Involved vehicles are marked “open” on the Investigate Vehicle History screen in GM Global Warranty Management system. This site should always be checked to confirm vehicle involvement prior to beginning any required inspections and/or repairs.

Parts

It is estimated that less than 1% involved vehicles will require parts replaced. Due to the small number of vehicles anticipated that will need this fix and the limited initial parts availability, dealers are encouraged not to order these parts for use as shelf stock.

Reminder: Parts may be removed from Retail Inventory Management (RIM). Dealers should review the affected parts to confirm RIM managed status. Parts may have quantity limiters in effect.

Warranty Information

Service Procedure

1. Remove the turbo heat shield. Refer to Turbocharger Heat Shield Replacement in SI.

2. Inspect the clamp between the turbocharger and the catalytic converter with the vehicle running.
   • If the clamp is properly aligned (1) and there is NO smell of diesel exhaust, no further action is required. Reinstall the turbocharger heat shield.

Note: It may be necessary to remove the catalytic converter to reposition the clamp if the clamp has seized due to heat or corrosion.

• If the clamp is misaligned (2) OR you can smell diesel exhaust, reposition the clamp if it is undamaged. If the clamp is damaged, replace the clamp. Refer to Catalytic Converter Removal in SI.

Dealers must take the steps necessary to ensure that the service update correction has been made to all involved vehicles in dealer inventory before selling or dealer-trading the vehicle, but no later than June 30, 2019.
