Inspection Before Removal
WARNING: This page is about a different car, the 2018 Nissan Titan XD. However, it is still accessible from the selected car via links, so may be relevant.
- With the engine stopped and the drive belt installed, record the drive belt tension generated by the existing drive belt auto-tensioner. Use a suitable tool to measure the tension in the drive belt.
Belt tension minimum
: 178 N (18.2 kg-f, 40.0 lb-f)
Belt tension maximum
: 365 N (37.2 kg-f, 82.1 lb-f)
NOTE: If the measurement is out of the specified range, replace only the drive belt and perform the tension test again. If a new drive belt has been installed and the measurement is still outside of the specified range, replace the drive belt auto-tensioner. - With the engine stopped, check the drive belt auto-tensioner arm, pulley, and stops for cracks (A). If any cracks are found, the drive belt auto-tensioner must be replaced.
- With the drive belt installed, verify that the drive belt auto-tensioner arm stop is not in contact with the spring case stop (A). If either of the stops are touching:
- Verify the correct drive belt part number is installed.
- If the correct drive belt is installed, replace the drive belt.
After replacing the drive belt, if the drive belt auto-tensioner arm stops are still in contact with the spring case stop (B), the drive belt auto-tensioner must be replaced.
- Check the location of the drive belt on the drive belt auto-tensioner pulley. The drive belt should be centered (A) on, or close to the middle of, the pulley. Misaligned drive belts (B), either too far forward or backward, can cause drive belt wear, drive belt roll-off, or increase uneven drive belt auto-tensioner bushing wear.NOTE: Drive belt misalignment is not always a result of a malfunctioning or faulty drive belt auto-tensioner. Make sure the adjacent pulleys and brackets are aligned and installed correctly.
