The serpentine belt is a crucial component in your 2005 Acura TSX, responsible for powering various engine accessories. Understanding its routing is essential for proper maintenance and replacement. Here's a comprehensive guide to help you navigate the serpentine belt system in your TSX.

Serpentine Belt Layout

The 2005 Acura TSX serpentine belt follows a specific path around several pulleys. The belt wraps around the following components in this order:

1. Crankshaft pulley

2. Air conditioning compressor pulley

3. Idler pulley

4. Alternator pulley

5. Power steering pump pulley

6. Tensioner pulley

It's important to note that the belt runs on the backside of the idler pulley, which helps maintain proper tension and alignment.

Belt Replacement Tips

When replacing the serpentine belt on your 2005 Acura TSX, keep these key points in mind:

  • Use a serpentine belt removal tool or a long 14mm combination wrench to release the tensioner pulley.
  • Turn the tool clockwise to loosen the belt tension.
  • Compare the new belt to the old one to ensure proper length and rib count. The TSX belt should have seven ribs.
  • When installing the new belt, start by looping it over the crankshaft pulley first.
  • Follow the correct routing, ensuring the belt sits properly in all pulley grooves.
  • Double-check the belt's position before releasing the tensioner.
