2000LX..172k miles...I had a hunch that my radiator fan was not working..the one on the passenger side..right?..with the engine running , when I turn on the aircondition the drivers side fan..condenser fan..starts spinning right away( It cycles on and off ).so I know thats working .im in Florida..In park I revved the engine for a while and the Rad. fan did not come on..perhaps I did not do it long enough..In any case I disconnected the harness and did a fan test directly from the battery bypassing the sensor and relay. Still the rad. fan did not work. I repeated the test procedure with the condenser fan and it worked..directly from the battery. Isn't reasonable to assume the Radiator fan is dead? I had a fender bender a while back and the rad fan was replaced..."Denso" brand is what I see on the condensor fan and the radiator replacement fan has no name..i guess its generic..any thoughts? If I might add..funny thing I dont have an overheating condition..The temp gauge always show that the engine temp is normal. Then again I rarely sit in traffic for any prolonged period.
