FAQs
Is this a smooth or grooved pulley?
The Gates T36079 is a grooved pulley featuring 6 grooves for v-ribbed belt systems.
Can I use this on a vehicle that uses a 5-groove belt?
No, this pulley is specifically designed for 6-groove belt systems to ensure correct tracking and load distribution.
What is the outer diameter of this pulley?
The outer diameter of the T36079 is 67.5 mm.
Does this pulley include a mounting bolt?
The product typically ships as the pulley unit itself; please check your specific packaging or reuse the existing mounting hardware if it is in good condition.
How often should an idler pulley be replaced?
It is generally recommended to inspect the idler pulley every time you replace the serpentine belt or if you hear abnormal noise from the accessory drive.
Troubleshooting
Persistent squealing noise after installation
Verify that the belt is correctly aligned within all 6 grooves of the pulley.
Pulley does not spin freely
Check if the mounting bolt is overtightened or if debris is trapped between the pulley and the bracket.
Belt tracking issues
Ensure the idler pulley is mounted perfectly parallel to the other pulleys in the drive system.
Pros and Cons

- 6-groove design prevents belt slippage
- Durable construction ensures long service life
- Easy installation for standard auxiliary systems
Cons
- Not compatible with smooth-surface idler applications
- Requires proper alignment tools for installation
- Specific 17 mm bore size limits universal application
Setup, Compatibility & Care
To install the T36079, first ensure the engine is completely cool. Use a socket wrench to relieve tension from the serpentine belt tensioner and carefully slide the old pulley off the mounting bracket. Before installing the Gates T36079, clean the mounting surface of any debris or oxidation. Ensure the bolt is torqued to the manufacturer's specification; over-tightening can compromise the pulley's rotation, while under-tightening may cause the pulley to detach.
Regular maintenance involves checking the pulley during every belt change. Rotate the pulley by hand; it should spin smoothly without any grinding noise or side-to-side play. If you feel any resistance or hear a dry, metallic rattle, the bearing inside the pulley has likely reached the end of its cycle and should be replaced immediately.
