which tool to take off old kitchen faucet?

[rachel_rz]

An old kitchen faucet stopped working. We are replacing it.
But we can't take off the old faucet.
Tried to loose the bolt/nut under sink,
tried wrench and other tools, but the space is so tight,
tried numerous bits, but nothing fit this nut.
Any suggestions? Thanks!

I use a deep well socket with a 12" extension. That works pretty well but if you don't have that, a basin wrench will work.

havasu, is spot on with his advice.

another method if the sink has been on the cabinet for a long time.

cut the caulk all the way around the sink, remove the p trap and pull the whole sink.

clean the cabinet, the sink also, change out old parts for new.

reset the sink in a new bed of caulk, dress up the caulking,

it will be good for another 10-15 years,
