1) Drain engine coolant. 2) Remove all cowling under the centre of the dash for access to the matrix.3) Remove two water pipes from matrix.4) Disconnect heater matrix valve cable.5) Remove matrix being careful not to spill water over the ECU.
Reverse instructions for refit.
6) With heater turned to maximum heat, top up cooling system with 50/50 anti freeze/water ratio.
Run vehicle and check that the radiator is free of all air and that the radiator fan cuts in when hot.
Run the car and recheck coolant level over the next few days of running in case of leaks.
Check under dash in case of leaks.

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.

SOURCE: Where is the blower resistor on a 2001 Nissan Sentra?

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.

Have a 92 Nissan sentra and the heater only blows cold air


let the engine warm up to operating temperature. turn on the heat full blast. feel the two hoses going to the firewall to the heater core; if they are both hot, then your problem is in the heater box or heater controls. if one hose is significantly cooler than the other, then you have a clogged heater core and you can replace it or try and backflush it.

Heater blowing cold air


My 05 sentra with 79k miles heat will warm up and then get cold after a mile of driving, we have tried to get the air pocket out, the mechanic stated he thought it could be a blown head gasket, another mechanic said it was a bad heater core. Any advice would be appreciated.
