How do you stop the steam on SOS island?

Answer 1

There are two steam challenges in the third rescue.

1) The radiator : beginning from the first open pipe, turn each swivel valve to direct the steam through closed pipes until it reaches the expansion joint at the upper left, which explodes. Enter the Boiler Room.

2) The Engineer: climb the center section to the upper right, and avoid the steam there. the engineer will show you how to stop the steam: she turns the Green valve, which is connected to another valve at the far left. Go there and turn that valve. Repeat the process for the other three pairs of valves:

Blue : middle right and then lower left

Orange : bottom right and then middle left

Red : bottom left and then middle left
