Rounded sump bolt

Post by F2paul » Fri Aug 09, 2019 4:59 pm

Not on my Tig but my sons Fiesta ST. He had been planing doing an oil change then baffled by really rounded off oil pan sump bolt , from last oil change at an Independent garage we ,had, used. So i tried hammering a size smaller socket on but no good. I ordered a set of sockets from Amazon that bite onto knackered bolts and was successful. So oil and filter change done and replacement sump bolt set up with torque wrench.
Just thought I would post this if anybody has a similar problem though appreciate most of our MK2 Tigs are still under the care of dealers. I know I could have tried a monkey wrench , or used a chisel but my arthritis isn`t up to all that hammering.

Irwin bolt extractors are a must in anyone’s garage. They have saved my bacon on my Mk2 Golf GTI a number of times!

Do the Tiguan not have a disposable plastic sump plug ?

Some options (from when I used to be a mechanic)

Grind some flats onto the bolt and use a big spanner (only if you can grind carefully)

Weld a nut onto the top

Replace whole sump and bolt

If its not in a difficult location, I would have tried 'stilsons' that grip more as more pressure is used.
