    FAQ

    A deflection or guide pulley for a V-ribbed belt is a component that directs and guides the belt along its correct path. Its function is to maintain proper belt alignment and tension, ensuring efficient operation of engine accessories such as the alternator, power steering pump, and air conditioning compressor.

    Key specifications include pulley diameter, width, bearing type, material, mounting design, and compatibility with the belt system. It must withstand continuous rotation, load, and engine heat.

    Replacement is necessary when the pulley is worn, noisy, or has a damaged bearing. Common symptoms include squealing noises, belt misalignment, or visible wear. It is often replaced together with the V-ribbed belt.

    Porza offers a fit guarantee option where your vehicle details are checked against product specifications to ensure correct compatibility.

    Porza provides high-quality belt drive components with fast delivery across Europe and options for online ordering or in-store pickup.

    If the fit guarantee is selected, compatibility is verified before shipping. If the product does not fit, it can be returned according to the return policy.
