Important Model-Specific Call-Outs for 2019 Husqvarna FX450
- The FX450 shares its engine with KTM and GasGas models, so oil change steps are similar to those models, but bolt torque specs and filter orientation can differ – always double-check the manual.
- This model has multiple drain plugs – at least one main and one screen plug. Don't skip either plug when draining.
- Be sure to remove and inspect both oil screens during the change; these are unique to Husqvarna's design and must be cleaned at every change.
- Capacity is 1.2 liters of oil – do not overfill, as Husqvarnas are sensitive to oil level.
- If your bike has an aftermarket skid plate, it may need to be removed for full access to the drain plugs.
Step-by-Step Oil Change Procedure
-
Preparation and Safety
- Run the engine for a few minutes to warm up the oil for easier draining.
- Shut off the engine and place the bike securely on a stand.
- Allow engine to cool enough to avoid burns.
- Put on safety glasses and gloves.
- Remove skid plate if necessary.
-
Remove Drain Plugs and Oil
- Locate main oil drain plug (bottom of crankcase), as well as the oil screen plug (often fitted on the right side under a small cover).
- Using your sockets or Allen wrench as required, carefully loosen and remove both plugs, allowing oil to drain completely into the drain pan.
- If the plug uses a crush washer, remove and set aside to be replaced.
- After the main flow slows, tip the bike slightly side-to-side to dislodge any trapped oil.
-
Remove, Inspect, and Clean Oil Screens
- Carefully remove the oil screens (one or both, depending on the model year/configuration) using pliers or the appropriate tool.
- Inspect the screens for debris, metal shavings, or buildup – a small amount is normal, but large particles could signal issues.
- Spray the screens with contact cleaner, wipe down, and set them aside on a clean towel.
-
Replace Oil Filter
- Locate the oil filter cover on the right side of the engine (typically 8mm or 10mm bolts).
- Remove cover bolts and the old oil filter. Take note of filter orientation – the open end usually faces outward, but confirm with the manual for the 2019 FX450.
- Clean the inside of the oil filter cavity with a clean, lint-free rag.
- Install the new oil filter, ensuring proper orientation.
- Replace/inspect O-rings on the cover and lightly coat with fresh oil.
- Reinstall the oil filter cover, torque bolts evenly and to spec (do not overtighten).
-
Reinstall Screens and Drain Plugs
- Install cleaned oil screens back into their bores.
- Install new crush washer on each drain bolt as required.
- Tighten main and screen drain plugs to factory torque specs (consult the manual, but typically 10–15 Nm/7–11 lb-ft).
-
Add Fresh Oil
- Insert funnel into oil fill opening.
- Pour in 1.1 liters (not the full amount; you will top off later) of recommended oil.
- Wait a few minutes, check for leaks at drain plugs and filter cover.
- Start engine, let it run for 30–60 seconds, then shut off and let the oil settle for 2–3 minutes.
- Check oil level via the sight glass or dipstick (if equipped). Slowly top off to the specified level, never above the max mark.
-
Final Inspection and Clean-Up
- Clean any spilled oil with contact cleaner and a rag.
- Reinstall skid plate if removed.
- Recycle old oil and filter responsibly – never dispose of oil in household drains.
- Take the bike for a short ride, re-check for leaks, and confirm oil is at correct level when hot.
Quick Tips for 2019 Husqvarna FX450 Owners
- Oil Change Interval: Husqvarna recommends oil changes every 10 hours of riding or after every race/event for optimal engine health.
- Filter Placement: The FX450 uses a specific oil filter type and orientation – always double check before installing.
- Drain Plug and Oil Screen: Forgetting either the screen or the crush washer can result in a slow oil leak. Replace crush washers every time.
- Capacity: Overfilling can cause excess crankcase pressure and leaks. Always use just enough to reach the correct mark.
