Good To Know

Q: Do I need to replace this gasket every time I open the pump housing? A: Yes, gaskets are single-use sealing components and should be replaced any time the housing is removed to ensure a leak-free seal. Q: Should I torque the housing bolts to spec? A: Always follow the service manual torque sequence to avoid deforming the housing or pinching the gasket.
