How to drain DEF tank on Volvo truck?

1. Place a drain pan / container capable of containing around 18 gallons (or if your able, perform this procedure when your DEF tank is about ¼ full, therefore not requiring you to drain so much DEF) underneath the DEF tank

2. Unscrew the drain plug on the bottom of the DEF tank, there is only one bolts in the tank itself and the metal housing has a cut out specifically for the plug

3. Drain the DEF and tighten the plug back up
