Installation Considerations
While specific installation steps vary by vehicle model and oil cooler design, the following general guidelines apply when installing the Dorman 926-601 Oil Cooler Assembly Seal Kit:
- Safety First: Always ensure the engine is cool and the vehicle is securely supported before beginning any work. Disconnect the battery if necessary.
- Drain Fluids: Depending on the oil cooler's location, it may be necessary to drain engine oil or coolant before removal.
- Clean Surfaces: Thoroughly clean all mating surfaces where the new seals will be installed. Remove any old gasket material, dirt, or oil residue to ensure a proper seal.
- Proper Orientation: Pay close attention to the orientation of each seal. Some seals are designed to fit in a specific direction.
- Lubrication: Lightly lubricate new rubber seals with clean engine oil or a suitable assembly lubricant before installation to prevent pinching or tearing.
- Torque Specifications: When reassembling, always refer to your vehicle's service manual for the correct torque specifications for bolts and fasteners related to the oil cooler or filter housing. Overtightening or undertightening can lead to leaks.
- Post-Installation Check: After reassembly, refill any drained fluids and run the engine to operating temperature. Carefully inspect for any signs of leaks around the newly installed seals.

Maintenance
Oil cooler seals are critical components that prevent fluid leaks. While they do not require routine maintenance beyond proper installation, it is advisable to periodically inspect the area around the oil cooler and filter housing for any signs of oil or coolant leaks during routine vehicle inspections or oil changes. Early detection of a leak can prevent more significant issues.

Troubleshooting
If you experience issues after replacing your oil cooler seals, consider the following common problems and solutions:
- Oil Leak After Installation:
- Cause: Improper seal seating, damaged seal during installation, incorrect torque on fasteners, or debris on mating surfaces.
- Solution: Re-inspect the installation. Ensure seals are correctly seated and not pinched. Verify fasteners are torqued to manufacturer specifications. Clean mating surfaces thoroughly before reassembly.
- Persistent Leak Despite New Seals:
- Cause: Crack in the oil cooler housing or filter housing itself, or a leak from an adjacent component.
- Solution: Thoroughly inspect the oil cooler and filter housing for cracks or damage. Confirm the leak source is indeed the seal area and not another component.
