Deliver pliers (tools) and a wrench to Valerie

Valerie is located in Vault City proper, in the maintenance building west from the Amenities Office. If you ask her what's wrong, she tells you that she needs a pair of pliers and a wrench.

Getting Pliers
The tool can be found all over (Klamath, and the Den. You can even buy one from a shop in Vault City!)

Getting a Wrench
Wrenches can be a bit harder to come by. Here are some options:
 * Curtis can tell you where one can be found after completing the Find Mr. Nixon quest.
 * You can find one on the third level of Vault 8 (Vault City's vault), in the storage room. NOTE: to enter the vault, you must either be a citizen of Vault City (or walk past the guards in combat mode). You also need a high lockpick skill).
 * You can find another one in Redding, at the Morningstar Mining headquarters, in a locker
 * Occasionally the general purpose store in San Francisco has them in stock

Reward
Once you have both the wrench and tools, return to Valerie. She thanks you grudgingly, then asks you to come see her the next day. Do that, and she'll give you a Super Tool Kit for your help.

NOTE: The Super Tool Kit (well, five of them, really, but she keeps the other four herself, unless you steal them) arrives a day after you deliver the wrench and pliers, so you'll have to wait a day before getting it from her.

In addition, if Vic and Val have had their argument, and you have completed this quest, you can ask her to give her Vic a chance for 250 further experience points.
