FAQ
Will this fit my LB7 or LLY?
Yes—this gasket fits 2001–2005 6.6L Duramax LB7 (VIN “1”) and LLY (VIN “2”) in Silverado/Sierra 2500HD/3500HD.
Do I need sealant?
Follow GM/MAHLE procedures. RCE gaskets are typically installed clean and dry unless the service manual specifies an approved sealant.
What else should I replace during a pump job?
Consider the pump itself, thermostat(s), outlet/bypass seals, and fresh coolant to avoid repeat labor.
