Dorman 904-801 GM 96-02 6.5L Diesel Mechanical Vacuum Pump
Replaces AC Delco Part# 215-479 Replaces GM Part# 12562793 Dorman Vacuum Pumps are 100% new, not remanufactured. Since they are new, they do not contain any used components that could lead to premature failure. Most premature failures occur with the bearing. A bearing failure will prevent the pump from producing vacuum. Depending on the vehicle, this may result in a loss of vent or temperature control inside the cabin, impaired or partial loss of braking or 4WD. Dorman has re-engineered the original needle bearing on the CAM which seizes, causing pump failure. Direct replacement for ease of installation Re-engineered radial ball bearing provides a greater load capacity for improved durability Mechanical and electric vacuum pumps available No core return hassles Housing Material: Metal Package Contents: Pump Assembly Pulley Included: No Vacuum Pump Connector: Barbed Vacuum Pump Drive System: Belt Drive Vacuum Pump Inlet: 3/8 In. Vacuum Pump Outlet: 3/8 In. Vacuum Relief Valve: Yes
