Bosch 1987948491 - V-ribbed belt 5PK 1432 mm

The Bosch V-ribbed belt drives the engine's ancillaries - the alternator, power steering pump, air conditioning compressor and water pump - transmitting torque from the crankshaft pulley. Made of abrasion-resistant polyurethane, it ensures stable system operation and limited stretch in service.

Belt parameters

Model 1 987 948 491 has 5 ribs and a length of 1432 mm, matching the original belts fitted at the factory in many popular models from the VAG group. The polyurethane material copes well with the high temperatures in the engine bay and with contact with oil and grease.

When to replace the belt

• Visible transverse cracks on the surface of the ribs
• Frayed or chipped rib edges
• Belt squeal at start-up or when turning the steering wheel
• Exceeding the mileage recommended by the vehicle manufacturer (usually 60-100 thousand km)

Installation

Replacement requires releasing the tensioner (by hand or with a wrench), taking the old belt off the pulleys and fitting the new one according to the routing diagram in the engine bay. It is recommended to check the condition of the tensioner and idler pulleys at the same time.

Specifications

Before buying, check compatibility with your specific vehicle model and year using the VIN or the original part number.
