FAN BELT

2002 Hyundai Sonata

Noises problem
2002 Hyundai Sonata 6 cyl Front Wheel Drive Automatic 36000 miles

I recently had my fan belt replaced because of a high pitched squealing noise, the belt was worn. The new belt is now making a noise, not as loud as the old, that goes away once the car is warmed up.

What could be the problem?

Hello –-

It appears that you need to replace your belt tensioner. I have attached that for you. Ensure you adjust as required.

[For 2.7L SOHC ENGINE]
The drive tension is adjusted automatically by the autotensioner.

NOTE: The belt tension must be measured between the specified pulleys. When a new belt is installed, adjust the tension to the center of the standard range indicated under "New." Let the engine idle for 5 minutes or more, and check the standard value indicated under "Inspection." When adjusting a used belt or a newly installed belt after 5 minutes or more of operation, refer to the standard value indicated under "Used." Refer to the standard value indicated under inspection for periodic inspections.

If the mean indicator is positioned over the max. position, replace the drive belt.
When replacing the drive belt, the mean indicator position must be between min. position and max. position.
