Frequently Asked Questions
Is this the right belt tensioner for a 2020-2026 Audi Q7 V6 3.0L?

Are the pulleys part of this Gates drive belt tensioner?
Yes. Gates 39527 is a single tensioner assembly with two pulleys, each 63 mm in outside diameter and 26 mm wide, plus a 17 mm bearing bore inside diameter.
Does the Gates 39527 box hold anything besides the tensioner?
The contents are one belt tensioner assembly.
How can I check a Gates 39527 belt tensioner for wear?
With the engine off and cool, look for uneven belt wear or a rough, cracked pulley. Squeal or rattling while driving can also point to wear; a shop can test the tension itself.
What does the spring and damping design in the Gates 39527 do?
The patented damping system absorbs extreme vibration, which is meant to extend the life of the tensioner, the belt and the accessories. The torsional round spring design gives consistent tension.
