A7 OOH Posted July 19, 2019 Share Posted July 19, 2019 Bit of a struggle to get too, can someone tell me the size of the drain plug -2005 1800 K series Link to comment Share on other sites More sharing options...
DJ. Posted July 19, 2019 Share Posted July 19, 2019 I can't remember the hex drive size, but access is much easier from above with the boot floor removed. I always findc the plug is very tight to undo.Duncan Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted July 19, 2019 Member Share Posted July 19, 2019 Do you only need the size of the hex recess (10mm), or the spec of the plug itself?As well as removing the boot floor you can manipulate the suspension to improve access.

SM25T Posted July 19, 2019 Share Posted July 19, 2019 I end up using a hex bit on a long breaker bar to undo it ... from above with boot floor out. Link to comment Share on other sites More sharing options...

Wrightpayne Posted July 19, 2019 Share Posted July 19, 2019 There is no drain plug on the sierra diff albeit you can suck the oil out of the filler hole. I did a write up a while ago where I used a Machine Mart oil syringe.RegardsIan Link to comment Share on other sites More sharing options...
Tom_Arundel Posted July 21, 2019 Share Posted July 21, 2019 I filed 2 flats on the plug boss and use a spanner (whack it with a hammer first!) Link to comment Share on other sites More sharing options...
ECR Posted July 21, 2019 Share Posted July 21, 2019 And I welded a 19mm hex head on mine. So much easier to undo. Link to comment Share on other sites More sharing options...
