Parts Desk Insights
Best Use Case: Replace a worn or leaking jet pump oil pump bellows during routine drive/oil pump service to help maintain proper oil pump sealing and operation. If the bellows is being serviced, inspect adjacent oil pump components and the mating areas during reassembly.
Common Issues: Common bellows-related concerns include oil seepage and degraded sealing performance over time. During installation, confirm the bellows seats correctly at the mating surfaces and verify related oil pump hardware is in good condition to prevent repeat service.
