Title: Manual transmission fill & drain plug washers
Post by: BrendanP on March 20, 2026, 15:43:57

I've changed the gearbox oil a couple of times on my 2015 diesel, and never bothered to change the crush washers. It could be they were stuck to the plugs and I didn't notice them. This time I will change them, and they seem to be a ridiculous price on-line, but my local Kia dealer supplied them for the princely sum of £1-01 each.
Part number is 17511 16000.
For the record, they are aluminium, 1mm thick. 23.7mm external diameter, 16.2mm internal diameter. This might be useful for anyone trying to find a 3rd party crush washer as an alternative to the original part.

Thanks for the hot tip, Brendan. There really should be no reason for aluminium washers of any type to be expensive.
