Product review (5 stars): Replaced this one too when my cold water one was leaking on LG washer
Water was puddling under the washer.  LG model WM2701HV about 7 yrs old.  Took top of washer off (undue the lower screw on the two brackets on each side in back of washer, and slide the top back about an inch, then lift off).  Noticed the original cold water valve was all corroded and leaking.  While I was replacing that one, I did this one too, even though hot was still OK.  Ordered this off Amazon.  Turn off water at the wall and unscrew the exterior washer hose.  Unplug the harness.  Use pliers to squeeze hose clamp and slide up hose an inch or two.  Twist off the hose, and put it on the new valve.  Unscrew the two screws holding the old valve in place on the back of the washer, and remove old one.  Install new one.  replace hose clamps and three harnesses.  Check for leaks.
