Raul asks Nicole to bring him the tire spoon and the wheel. It's not a difficult task since the broken motorcycle wheel stands against the red locker (left from Raul) and the spoon lays near a large bowl in the left side of the workshop (close up). She hands the items to Raul (talk to him twice).
She moves to the right side of the workshop and takes a look at the compressor (close up) and picks up the tube. She presses the green button on the device and attaches the tube to the compressor to fill it with air.
Now time becomes an issue - Nicole has to pick up the tube and dash to the fountain before the air gets out of it completely - she needs to put it into the water to locate the leak. She marks the spot with the blue marker (you need to do all that before the timer on the left reaches 0). She then heads back to the workshop where she informs Raul where the hole is only to learn that she should look for something to patch the hole.
She heads back to the antique store and asks the old man about the umbrella she plans to use as a pole. After she agrees she takes the umbrella from the stand and goes into the garden, then tries to pull the piece of gum down from the roof. After getting it she heads back to Raul, who asks her to cut out a patch for the leak. Nicole uses the scissors she picked up earlier and cuts the gum to create a patch, and talks to the mechanic to receive a fixed wheel, which needs to be filled with air using the compressor.
