4. Installation (Setup)
The following are general steps for replacing an oil filter. Always refer to your generator's owner's manual for detailed, model-specific instructions and torque specifications.
- Prepare the Generator: Ensure the generator is turned off, cooled down, and the spark plug wire is disconnected. Place a drain pan beneath the oil drain plug.
- Drain Old Oil: Remove the oil drain plug and allow all old engine oil to drain completely into the pan.
- Remove Old Filter: Position the drain pan under the oil filter. Use an oil filter wrench to loosen and remove the old oil filter. Be prepared for some oil to spill from the filter.
- Prepare New Filter: Apply a thin film of new engine oil to the rubber gasket of the new Generac 070185ES oil filter. This ensures a proper seal.
- Install New Filter: Thread the new oil filter onto the engine by hand. Once the gasket makes contact with the engine, tighten it an additional 1/2 to 3/4 turn, or as specified in your generator's manual. Do not overtighten.
- Refill Engine Oil: Replace the oil drain plug and tighten it to the manufacturer's specifications. Refill the engine with the recommended type and amount of new engine oil, as specified in your generator's manual.
- Check for Leaks: Reconnect the spark plug wire. Start the generator and let it run for a few minutes. Shut it off and check for any oil leaks around the filter and drain plug. Check the oil level and add more if necessary.
- Dispose of Waste: Properly dispose of the old oil filter and used engine oil at an authorized recycling center.

5. Function and Best Practices
The Generac 070185ES oil filter plays a critical role in your generator's engine health by removing contaminants from the engine oil. A clean oil filter ensures that the engine receives clean oil, which is essential for reducing wear on internal components and maintaining optimal performance.
- Regular Replacement: Adhere strictly to the oil and filter change intervals recommended in your generator's owner's manual. This is typically based on operating hours or time elapsed.
- Use Genuine Parts: Always use genuine Generac replacement parts, such as the 070185ES oil filter, to ensure compatibility, performance, and to maintain any applicable warranties.
- Proper Oil: Use the type and viscosity of engine oil recommended by Generac for your specific generator model.
6. Maintenance
The primary maintenance task related to the oil filter is its timely replacement. Regular oil and filter changes are the most important maintenance procedures for extending the life of your generator's engine.
- Scheduled Intervals: Consult your generator's owner's manual for the recommended oil and filter change schedule. This schedule is typically provided in terms of operating hours (e.g., every 100 hours) or calendar time (e.g., annually), whichever comes first.
- Inspection: During oil changes, visually inspect the area around the oil filter for any signs of leaks or damage.
7. Troubleshooting
If you encounter issues related to the oil filter, consider the following:
- Oil Leaks After Replacement:
- Ensure the old gasket was completely removed from the engine block.
- Verify the new filter's gasket was lightly oiled before installation.
- Check that the filter is tightened correctly (hand-tight plus 1/2 to 3/4 turn, or as per manual). Do not overtighten.
- Inspect the filter for any visible damage or defects.
- Incorrect Fit: Double-check that you have the correct Generac 070185ES filter for your specific generator model. Refer to the compatibility list in Section 3.2 and your generator's manual.
- Engine Performance Issues: While an oil filter is critical, engine performance issues are rarely solely due to a new, properly installed filter. If issues persist after an oil and filter change, consult your generator's owner's manual for further troubleshooting or contact a qualified service technician.
