I can get you a diagram on monday but it goes from the alternator to the power steering pump then around the tensioner pulley then around the crank pulley then to the a/c compressor then pull on the tensioner to give you some slack and slip it on the waterpump.I hope that helps.Let me know if you still need the diagram

Hi maroon,

• Get a 14mm or 9/16" socket and a long handled ratchet or breaker bar.
• Get the belt around all the pulleys except the A/C compressor or Alternator. Double check your routing.
  
• 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

On my 2005 Tacoma with the 4.0L V6, I found it easier to change the belt from under the truck. Just remove the skid pan. Plenty of room to install the belt. The tensioner pulley is the one at about 2-o'clock from the crankshaft with the belt nearly all the way around it.

To loosen and remove the drive belt on a 2004 Toyota 1.4L engine you simply use a wrench and pull up on the spring-loaded tensioner.
You should be aware, however, that if you are experiencing problems with belt squeal or rattling noise, there is a Technical Service Bulletin (TSB) for your vehicle that provides information for an updated tensioner assembly.
