Sump Plug Washer 18mm suitable for Toyota LandCruiser and Toyota Hilux – Engine Gearbox and Diff Drain Plugs
This is an aftermarket metal washer with an 18mm inside diameter. It seals the sump drain plug on Toyota engines from the early 1970s through to around the early 1990s, when most models changed to a 12mm sump plug. The same 18mm washer also fits most Toyota gearbox, transfer case and diff filler and drain plugs, so it is worth having a few on hand when you service the driveline. The price is for one washer.
🚗 Suitable for:
- Toyota LandCruiser 40 Series BJ40, BJ42, FJ40, FJ45 and HJ47
- Toyota LandCruiser 60 Series FJ60, FJ62, HJ60 and HJ61
- Toyota LandCruiser 70 Series BJ70, BJ73, BJ74, FJ70, FJ73, FJ75 and HJ75, up to the change to a 12mm sump plug in the early 1990s

❓ FAQs:
Q: 12mm or 18mm, which do I need?
A: Engines from about the early 1990s on mostly use the 12mm washer. Older engines and most gearbox, transfer and diff plugs use this 18mm washer. Measure your plug or send us your VIN.
Q: Can I reuse the old washer?
A: We don’t recommend it. It crushes to seal, and a used one is more likely to weep oil.
