Big Nuts and Bolts

To maintain your VW you will need a metric socket set and some wrenches but typically these sets only cover 8-19mm and even then they aren't complete 12pc sets.

I've compiled a list of uncommon size tools you will require to maintain your Baywindow bus. These are only some of the tools you'll need to do everything yourself but this list covers the common ones for maintenance.

Note: when you see a bolt size in Bentley it's only referring to the width of the threads. The diameter of the head of the nut/bolt and thus the size of the tool you will need is rarely mentioned.
