DHD 900-101 Duramax Engine Oil Cooler Install Kit 2001-2010

Use this kit when replacing/installing your engine oil cooler. New GM oil coolers do not come with the gaskets. This kit does not include the thick green block seal required on some replacement GM oil coolers. If you suspect you need that seal, order # 12631281.

This kit does not include any seals for the engine oil cooler housing itself. For a complete seal kit with full coverage to do the job, see our Deluxe Seal/Install kit DHD 900-100.
