VIDEO: Decoupler Pulleys
Andrew Markel shows how decoupler pulleys overcome belt issues like slippage from speed variations to keep the engine running efficiently.
Diagnosing Alternator Pulleys
When faced with an illuminated charge light diagnosis on most late-model vehicles, do not automatically assume the problem is inside the alternator and potentially unserviceable. The problem could be the pulley and belt drive system. Neglecting to test and diagnose the pulley can lead to unnecessary replacement.
Tension Pulley Installation: CT 887 for Daewoo and Chevrolet Aveo 1.4 16V, 1.5 16 V, 1.6 16 V
The moving indicator on the tension pulley breaks off during installation and severely damages the belt. Possible causes include: 1) Failure to loosen the water pump and to use it for adjusting the tension as described in the instructions; and 2) During the specified two full rotations of the engine at increased tension (hole marking on the base plate), the limit stop is subjected to excessive load and the moving indicator breaks off.

Avoiding Alternator Comebacks: Did Your Supplier Provide the Right Pulley?
Automotive repair businesses that install remanufactured alternators are urged to verify that their units are equipped with overrunning alternator decoupler (OAD) pulleys for the growing number of late-model vehicles now requiring this advanced technology.

Toyota Supercharger: Squeak/Rattle Noises From Idler Pulley
Due to a possible out-of-tolerance condition on the idler pulley shaft, some pulleys may have bearings that spin on the inner shaft and may cause a squeaking or rattling noise. The supercharger may be perfectly fine and the source of the noise may simply be the idler pulley.

Inspection Tips For Chain-Driven Water Pumps
If one water pump fails sooner and is replaced without an investigation, the new pump is likely doomed.
Alternator Testing For No Charge Conditions
Many alternator problems turn out to be nothing more than a bad connection at the alternator or a bad wiring harness.
