yeah it didn't work well, lol. trid this on my girlfriends 98 sentra. EDIT: i just realized i put this in b13, force of habbit. oops.
i was attempting the two bucket method, wherby you disconnect the hose that goes into the radiator and rout one end into and empty bucket and have the other sucking from a full bucket of clean ATF.
well, it was hard enough to disconnect the hoses...very stubborn. then i found i had the wrong size tubing (3/8" ID as opposed to 5/16" ID), but i tried it anyway. i hoped zip ties would seal it off...they didn't. a mild ATF drip and no suction.
so i got the right size tubing...but forgot to put zipties on the barbs. about 3 seconds in the hose popped off and sprayed the entre engine with ATF, and most of the garage floor.
third time i implimented zip ties. all went as planned except no suction? there was a little, but not enough to pull the ATF up from the bucket. oh well.
i ended up doing a drain and fill 3 times, i think its just as good as a flush, and i called it a night. lesson learned, just drain and fill the damn thing! lmao, it was all fun though.
BTW: it took 3 gallons of cat litter to clean up the spilled ATF, lol.
