Fleece Billet Coolant Block Off Plate 01-19 6.6L GM Duramax AERO-3030XL A must for the enthusiastOkay, lets be honest, yes, this part looks awesome, but once installed, you're not likely to see it. That being said, it absolutely serves a purpose by curing the notorious rear block off coolant leak on all Duramax's. The factory cover is known to leak over time, so this unit from Fleece is built thicker than the stock plate and features an integrated o ring for a superior construction that will not leak over time.
