Regular oil changes are essential to keep your 2019 Husqvarna FE350 HQ running strong and delivering peak performance on every ride. This step-by-step MotoSport.com guide details the exact process, highlights important model-specific tips, and lists the precise tools you’ll need.

Tools and Materials Needed

  • Socket wrench set (13mm recommended for drain bolts)
  • Torque wrench (for precise reinstallation of bolts)
  • Flat-tip screwdriver (for removing the oil screen and filter cover)
  • Oil drain pan
  • Oil filter (compatible with Husqvarna FE350 HQ)
  • Fresh engine oil (refer to service manual for type and viscosity; typically 10W-50 full synthetic for this model)
  • New crush washers (for oil drain plug and oil screen cover)
  • Measuring cup (to ensure accurate oil fill volume)
  • Contact cleaner or brake cleaner (for cleanup)
  • Clean shop rags
  • Funnel
  • Pin wrench or needle-nose pliers (to remove and insert the oil screen)
  • Owner’s manual (for reference to torque specs and oil capacity)

Step-by-Step Oil Change Instructions

  • Warm up your engine: Briefly run your FE350 HQ for 2–3 minutes. This warms the oil, ensuring it drains completely.
  • Place the bike securely: Prop your dirt bike upright on a stand to keep it level throughout the procedure.
  • Remove the skid plate (if installed): If your bike has a skid plate, unbolt and remove it for easier access to the oil drain plug and screen.
  • Drain the oil:
    • Place the drain pan directly under the engine’s drain plug.
    • Using your socket wrench, remove the main drain plug (located on the left side of the engine case). Allow the oil to drain fully.
    • Don’t forget the oil screen plug (located on the lower right side of the engine). Remove this and let any remaining oil flow out.
  • Remove and clean the oil screens:
    • The FE350 HQ features an oil screen accessible behind a threaded plug. Remove the cover and extract the oil screen using a pin wrench or needle-nose pliers. Clean the screen thoroughly with contact cleaner and let it dry before reinstalling.
  • Replace the oil filter:
    • Locate and unbolt the oil filter cover (right side of the engine).
    • Remove the old oil filter. It’s recommended to “pre-soak” the new oil filter in a bit of engine oil to saturate the media before installing it.
    • Slide the new filter in place, ensuring it is properly seated.
    • Clean and inspect the oil filter cover O-ring, replacing it if damaged.
    • Reinstall the oil filter cover and tighten to the manufacturer’s specified torque.
  • Reinstall and torque all plugs:
    • Clean all sealing surfaces and threads. Fit new crush washers where required to prevent leaks.
    • Install and hand-tighten both the main drain bolt and the oil screen plug, then torque them to spec (typically around 15 Nm, but always confirm in your service manual).
  • Refill with fresh oil:
    • Insert the funnel into the oil filler opening on the right side of the engine.
    • Pour in the correct amount of oil. For the 2019 Husqvarna FE350 HQ, it’s typically 1.2–1.3 liters (about 1.27 US quarts), but always double-check your manual for precise capacity.
    • Add the oil in increments, pausing to check the level in the sight glass. The oil should sit between the top and bottom marks when the bike is upright.
  • Start the bike and check for leaks:
    • Run the engine for about 60 seconds. Keep an eye out for any oil leaks around the drain plug, screen plug, or oil filter cover.
    • Shut off the engine, allow oil to settle for a couple of minutes, then recheck the oil level and top off if needed.
  • Dispose of old oil and filter properly: Take your used oil and filter to a certified recycling center or automotive shop that accepts them.

Model-Specific Tips for the 2019 Husqvarna FE350 HQ

  • Oil changes are recommended every 10–15 hours of riding, or sooner after heavy clutch use, extended trail riding, or racing conditions.
  • Always use a new crush washer on both the drain plug and the oil screen cover to prevent leaks. Never reuse the old washers.
  • Pre-oil the new filter: Adding a small amount of clean engine oil to saturate the filter before installation helps prevent dry starts and ensures oil galleries fill quickly during the first start-up after an oil change.
  • Be careful not to overtighten the drain plugs. Over-torquing can strip threads or damage the engine case. Use your torque wrench for accuracy and consult your owner’s manual for specs.
  • Check the sight glass carefully: Oil level should always be checked with the bike standing upright and level, not on the side stand.
  • The oil filter and screen design is shared with KTM/Husqvarna 250/350/FE models of the era, so many aftermarket filter kits and tools will be compatible.
  • For best longevity, many riders opt to change oil every 5–10 hours during hard riding or racing conditions.
