DHD 030-5001 Billet Rear Engine Cover Coolant Block Off Plate
DHD's Billet Coolant Passage Block Plate is used to stop the problematic Duramax coolant leak where the stock cast plate is installed on the rear engine cover. Use this to fix your current coolant leak or to prevent a possible future coolant leak. The plate is machined out of a block of billet aluminum and has a built in O-Ring for a 100% leak proof seal. No gasket is required for installation.
Note: This is an excellent upgrade to perform when changing, upgrading downpipes. We recommend accessing this plate via the passenger side wheel well.
