Is it dangerous to drive with a worn pulley?

A pulley that fails completely can throw the belt off, disabling charging and other belt-driven accessories — repair before this happens.

Do some alternator pulleys have a special "decoupler" function?

Yes, many modern vehicles use an overrunning alternator pulley (OAP) or decoupler pulley, which absorbs engine vibration and can freewheel slightly for smoother belt operation — these can fail independently of the alternator itself.

What is the pulley made of?

Steel or reinforced composite, sometimes with an internal freewheel or damping mechanism.

What is this part and why does it matter?

I ordered a Heater Blower Motor Resistor for a Toyota Avensis. Delivery took eight days from Latvia to Ireland. I installed it, and everything works perfectly. I wish this company success.

No complaints about Evro Trans itself, everything's fine. But the delivery..... It felt like the order was being carried by turtles. 4 days from Riga to Daugavpils. Judging by the tracking, the parcel just sat somewhere behind a shed for 3 days, then they found it and delivered it the next day. I think that's why I won't be ordering there again.

Bought a front fender for my car. I liked it! After payment they sent more than 20 photos of the problem areas, and it was packed very securely - took a while to unwrap.
