Is it dangerous to keep driving with a worn tensioner?

Yes, a failing tensioner can let the belt slip or come off entirely, disabling the alternator, power steering, and other belt-driven systems — repair promptly.

Should the belt be replaced along with the tensioner?

It’s recommended, especially if the belt shows any cracking or glazing — it’s a similar labor job to do both together.

What is the tensioner made of?

A spring-loaded metal arm with a pulley bearing at the pivot point.

What is this part and why does it matter?

The tensioner pulley maintains correct tension on the accessory drive belt, keeping it from slipping while allowing for length changes as the belt wears.

Signs of a faulty part

If you notice any of the following, the part likely needs replacement:

Squealing or chirping noise from the belt area
Belt slipping when accessories (A/C, power steering) are under load
Rattling noise from the tensioner itself, especially at idle

Installation information

Bolts to the engine block — release tension carefully when removing, as the spring mechanism can snap back with force.

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.
