Replace heater core in 2001 nissan sentra - 2001 Nissan Sentra

SOURCE: How do I replace a serpentine belt for a 2001 nissan sentra.

Hi gj,

It's easy and you won't need a prybar.

• Get a 14mm or 9/16" socket and a long handled ratchet or breaker bar.
• For putting the belt on: Get the belt around all the pulleys except the A/C compressor or Alternator.
• The tensioner pulley is on a spring loaded arm. Get your socket on the center nut of this pulley.
• Slowly pull the ratchet toward the center of the engine. The pulley will pivot on the arm allowing you to get the belt on the final pulley.
  
• Slowly release the tension.
  
• You're done

You can't find one, because it doesn't have one.

Its actually not that bad to change. If you open the glove box and remove the screws then the screws along the bottom of the glove box at the bottom of the dash the box will slide out. Remember to disconnect the light if it has one. Now you will be able to see the underside of the dash. You can see a large black box that has wires and vacuum lines all over. You need to locate a small flat plate with two screws and a plug in the middle. Disconnect the plug and remove the screws. The resistor will come straight out. The back side will look like small coiled up springs of different sizes. Install in reverse.Hope this helps. Good luck. Please re-post with updates. Thanks cj2176.
