Product Details

Electric Vacuum Pump (904-857) by Dorman®. 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.

Works Great

I had an awful noise coming from the front of the truck and it was the old vacuum pump giving up the ghost. I bought this one and it was simple plug and play taking out the old one and putting this one in. It's been 2 months of driving and I haven't had any issues with it and the noise is gone. I didn't have any error coeds come up and it's been great.
