V-belts
The drive belt drives the alternator and water pump.
A slipping drive belt leads to a lower battery charge current and reduced coolant circulation.
Replacing a drive belt in time before it breaks down involves only minor costs, but is vital for operational reliability.
Drive belts must be at the correct tension; they must not be pressed in more than 5 mm between the pulleys.
It is also important that the drive belt is not torn or fringed.
The rubber in the original Volvo Penta drive belt is unique in composition.
The belts have coarse-cut open side walls, where the rubber fibers are placed crosswise.
This provides the belt with both longitudinal flexibility and high lateral strength, qualities which lead to better grip and a precise fit in the pulleys.
