Heist Prep: Maintenance Gear Part 2

"Now, more prep for the handyman con. We need a maintenance van and some maintenance to do. Something major... maybe we pour hazardous chemicals into the roof ventilation. I don't know. Just... get a Water & Power van from the location on your GPS and we'll talk."

- Lester's briefing.

Maintenance Gear Part 2 is an optional prep mission featured in Grand Theft Auto Online as part of the The Diamond Casino Heist update. It is a freeroam mission needed to progress The Diamond Casino Heist. The player must have completed Maintenance Gear Part 1 in order to play this mission. Completing this mission allows players to use the Los Santos Department of Water & Power maintenance worker entrance disguise in the The Big Con Approach.

Overview
Lester informs the player that they still need both a maintenance van and some maintenance work to be done at the casino. First, he sends them to a warehouse in Cypress Flats to steal a LSDWP Boxville van from some workers. When inside the van, the workers do get hostile, but they can easily be outrun. After that, the player heads to the roof of the Casino and dumps hazardous chemicals into a ventilation unit. After this is done and the van is delivered to the Arcade, the mission is complete. The player also gets to keep the Hazardous Jerry Can used in the prep, but the liquid doesn't do anything in Freemode.

Lester Dialogue
"It's fate, that van is loaded with chemicals. Head over to the casino and take 'em up to the roof."

- After stealing the van.

"Almost there, find the broken vent and dump all that poisonous goo. By the time it burns through the system, we'll be ready to roll. Then bring back the van to Planning when you're done."

- After arriving at the Casino.
