Parts for your 2007 Suzuki Sx4-Sump plug washers

2007 Suzuki SX4 sump plug washers — fitment, purpose and servicing tips

Yes, the 2007 Suzuki SX4 does use a sump plug washer. Technical sources that specify a replaceable oil drain plug gasket (washer) for this model include: the Suzuki SX4 Service Manual (2006–2010, Publication No. 99500-80J00-01E) in the engine lubrication section, which instructs refitting the drain plug with a new gasket at oil changes, the Suzuki Electronic Parts Catalogue (EPC), which lists a 14 mm oil drain plug gasket commonly referenced as part number 09168-14015 for SX4 variants, and the 2007 SX4 owner’s handbook oil-change guidance noting reinstallation with a new gasket and correct torque.

On a 2007 Suzuki SX4, the sump plug washer is a small, single-use crush ring (typically aluminium or copper) that seals the drain plug to the sump. It squashes ever so slightly as the plug is tightened, filling tiny imperfections so fresh oil stays put and doesn’t mist or drip onto the driveway. It also helps the plug reach accurate clamping load without over-tightening, protecting the sump threads.

Best practice is to replace the washer at every oil and filter change. They’re inexpensive, and reusing a flattened washer is a false economy. If the washer’s surface is scored, the plug needs extra nip to stop a weep, or there’s a faint oil halo around the plug a few days after a service, it’s time for a new one. The SX4 typically takes a 14 mm internal-diameter crush washer, OEM sizing and profile are spot on for the sump face, so keeping a couple of genuine or quality aftermarket spares on the shelf makes life easy.

When servicing the 2007 Suzuki SX4 sump plug washer, cleaners or sealants aren’t needed. Simply wipe the sump seating face clean, fit a fresh washer, and tighten the plug to the torque specified in the Suzuki manual for the exact engine variant. While under the bonnet, it’s smart to check the plug head and threads, and if the plug is the magnetic style, clean any swarf off the tip before reinstalling. Owners doing higher kilometres or frequent short trips will benefit from sticking to consistent oil change intervals and always pairing that with a new washer—cheap insurance against leaks and stripped threads.

• Replace the washer at every oil change or any time the plug is removed.
• Watch for tell-tales: fresh oil mist, dampness around the plug, or driveway spots.
• Use the correct 14 mm ID crush washer (common OEM ref: 09168-14015) and torque to the Suzuki spec for your engine.

Popular questions about 2007 Suzuki SX4 sump plug washers

What size sump plug washer does a 2007 Suzuki SX4 use?
Most 2007 SX4 models use a 14 mm internal-diameter crush washer on the sump drain plug. A common Suzuki OEM reference is 09168-14015. Variants can differ, so it’s sensible to confirm by VIN or by matching the original washer.

Should the sump plug washer be replaced at every oil change?
Yes. The washer is designed to deform once to create a reliable seal. Reusing it can lead to minor oil seepage or the need to overtighten the plug, which risks damaging threads in the alloy sump.

Can a copper washer be used instead of aluminium on the SX4?
Yes—so long as the size and profile are correct. Both copper and aluminium crush washers work well. Copper can be annealed if reused in a pinch, but for this model it’s better to fit a new washer at each service.
