Shop parts for a 2009 Suzuki DRZ400SM Dirt Bike.
Changing the oil regularly on your 2009 Suzuki DR-Z400SM is essential for optimal performance and engine longevity. The process is straightforward but does require careful attention to specific steps and awareness of unique features on this make and model. The following guide provides step-by-step instructions, highlights required tools and materials, and notes important considerations specific to the DR-Z400SM.
Tools and Materials Needed
- Ratchet (socket wrench)
- 8mm, 12mm, and 17mm sockets
- Torque wrench
- Drain pan
- Funnel
- Oil filter
- New engine oil (10W-40, 2 quarts – 1.8 liters with filter change)
- Clean rags
- Replacement washer for drain bolt (recommended)
- Gloves & safety glasses (optional for protection)
Preliminary Steps
- Warm up the engine by running it for five minutes. This helps the oil drain more completely by lowering its viscosity.
- Turn off the engine and allow the bike to cool for a couple of minutes.
- Place the bike on a stable stand to keep it upright and secure during the procedure.
Step-by-Step Instructions
-
Remove the oil filler cap/dipstick.
The filler cap/dipstick is located at the top of the frame, near the throttle side. Removing it allows air in, letting oil drain faster and more thoroughly.
Tip for DR-Z400SM: The filler cap location can be tight–use a rag to keep the area clean and prevent contaminating the engine when you refill.
Caution: Oil may be hot after warming the engine. Wear gloves. -
Drain the crankcase oil.
Position a drain pan under the crankcase. Use a 17mm socket to remove the crankcase drain bolt and its washer on the bottom of the engine casing. Let the oil drain completely.
Inspect the washer for any deformation and replace if needed to prevent leaks.
Note: Always double-check that the used oil is fully drained before moving to the next step. -
Drain the oil from the frame.
Move the drain pan underneath the lower frame tube and use a 12mm socket to remove the frame drain bolt and washer. More oil will drain from here.
Replace the washer if it is damaged or excessively worn.
Model-Specific Callout: The DRZ400SM has an additional frame oil drain. Don–t skip this step—missing it will leave dirty oil in the system.
Tip: Not all dirt bikes have this separate frame drain; it's critical for the DR-Z400 series. -
Reinstall drain bolts.
When oil is fully drained from both the crankcase and frame, reinstall each drain bolt with its washer.
Tighten the crankcase (17mm) and frame (12mm) drain bolts to 15 ft-lb using a torque wrench to avoid over-tightening and potential damage.
Best Practice: Start threading the bolts by hand to avoid cross-threading. -
Replace the oil filter.
The oil filter housing is typically held by 8mm bolts. Loosen and remove them, then carefully remove the old oil filter.
Wipe the filter area clean with a rag.
Install a new oil filter (make sure to lube the rubber gasket on the new filter with a little fresh oil). Replace the two O-rings–one small, one large–if your filter kit supplies them.
Reinstall the oil filter cover and tighten the bolts evenly until snug.
DR-Z400SM Tip: The oil filter cover can be replaced in either direction but install it in the OEM orientation for best fit and sealing. -
Add new engine oil.
Place a funnel in the oil filler opening.
Pour in 1.8 liters (1.9 quarts) for oil and filter change; only about 1.7 liters needed if you do not change the filter.
Use 10W-40 motorcycle-specific oil.
Replace the oil filler cap/dipstick. -
Check oil level.
Start the engine and let it idle for about 5 minutes. Shut off and wait 2–3 minutes.
Use the dipstick to check oil level (with the bike level and upright, not on the side stand). Add oil if needed to reach the upper mark.
DR-Z400SM Specific: Underfilling is common due to the dual-drain design; always check again after running the bike briefly. -
Inspect for leaks and reinstall any removed skid plates.
Double-check all drain plugs, filter area, and filler cap for leaks.
Reinstall the skid plate (if removed) before riding. Final tip: Dispose of old oil and filter properly at a recycling center.
