the thermostat is located at the engine end of the lower radiator hose inside of the housing that the radiator hose connects to.
The flasher button on a 2001 altima is above the middle air conditioner vents by the dash. It is a sort of square button that you push in to make them come on and push in again to turn them off.
what solenoid?
If your 2001 runs like my 2003...I'm dumping it before 100,000 miles!!
Hi,I have the Nissan Altima 2001 too and the overdrive switch in on the gear shifter handle and just below the shift push button.
