Belt Tensioner With Belt Length Indicator
3. Check that the belt length indicator, if equipped, on the belt tensioner is in the acceptable belt installation and wear range. If the indicator is in the
belt replacement range, either an incorrect belt is installed or the belt is worn beyond the service limit. Install a new belt as necessary.
4. Eliminate all other non-belt related noises that could cause belt misdiagnosis, such as A/C compressor engagement chirp, A/C slugging noise,
power steering cavitations at low temperatures, variable camshaft timing (VCT) tick or generator whine.
5. If a concern is found, correct the condition before proceeding to the next step.
