Parts for your 2020 Suzuki Splash-Sump plug washers

2020 Suzuki Splash sump plug washers

Based on Suzuki technical literature for the K12B/K10B engines used in the Splash (Workshop Manual: Periodic Maintenance section, Suzuki Electronic Parts Catalogue listings for “Gasket, Oil Drain Plug”), the 2020 Suzuki Splash uses a replaceable crush-type sump plug washer. These sources specify a separate sealing gasket for the oil drain plug and instruct replacing it whenever the plug is removed during an engine oil change. Typical Suzuki listings show an M14 drain plug with an aluminium or copper crush washer.

On the Splash, the sump plug washer’s job is simple but crucial: it provides a one-time, deformable seal between the sump and the drain plug to stop oil seepage. When the plug is torqued, the soft aluminium or copper washer compresses to fill tiny imperfections, preventing drips that could otherwise leave spots on the driveway or, worse, lower the oil level over time. Because it crushes to seal, it’s designed for single use.

Best practice for this model is to fit a new washer at every oil change. The Suzuki workshop guidance backs this up, as reusing a flattened washer risks weeping around the plug. A fresh washer also means the plug can be tightened correctly without overtightening—handy for protecting the alloy sump threads. A typical tightening torque for many Suzuki M14 sump plugs is around 35 N·m, but they should confirm the exact spec in the service data for their vehicle.

Signs the washer needs replacement include a sheen of oil around the drain plug, a drip forming after a drive, or a visibly crushed, grooved, or hard washer during removal. If any of these show up, a new washer is cheap insurance. Most quality aftermarket 14 mm crush washers (aluminium or copper) will do the trick, though many prefer aluminium for Suzuki sumps.

Basic servicing tips for the Splash’s sump plug washer:

• Warm the engine slightly so the oil flows, but don’t work on a hot sump.
• Always have a new 14 mm crush washer ready before you crack the plug.
• Clean the plug and sump face, fit the new washer, and torque to spec.
• After refilling oil, run the engine, then check underneath for any weeping.

Done right, a fresh washer each service helps keep the Splash tidy, leak-free, and easy to maintain over the long haul.

FAQs

What size sump plug washer does a 2020 Suzuki Splash use?
Most Splash models with K12B/K10B engines use a 14 mm crush washer on the M14 drain plug. Aluminium or copper versions both work, aluminium is commonly supplied by Suzuki. If in doubt, match the old washer or check the VIN against a parts catalogue.

How often should the sump plug washer be replaced?
It should be replaced every time the drain plug is removed—usually at each oil change. The washer is a crush-type seal and is designed for one-time use to maintain a proper, leak-free seal.

What torque should the drain plug be tightened to?
A common figure for Suzuki M14 sump plugs is around 35 N·m, but they should always confirm with the specific service data for their Splash. Using a torque wrench helps avoid overtightening and protects the sump threads.
