This alternator and power steering V-belt is a versatile replacement belt used across several Volkswagen Type 25 (T3) and early T4 Transporter models, covering both Waterboxer petrol engines and diesel T4 applications. Manufactured to the correct width and length, it ensures reliable drive to essential engine accessories under everyday and long-term use.
On Waterboxer engines, this belt is responsible for driving either the alternator or the power steering pump, depending on engine year and configuration. Correct belt tension is critical: too loose and the belt can slip, reducing charging output or steering assistance; too tight and it can overload bearings in the alternator or pump. This belt matches original specifications to maintain proper tension and alignment.
On early VW T4 diesel engines, the same belt size is used to drive the alternator, making it a practical multi-application solution for workshops and owners maintaining more than one model.
How it works
The belt transfers rotational force from the crankshaft pulley to driven components such as the alternator or power steering pump. Its reinforced rubber construction allows it to flex around pulleys while resisting stretch, heat and wear. Correct sizing ensures smooth power delivery, reduced squeal, and long service life.
Fitment notes
Always check pulley alignment and condition before fitting
Belt tension should be rechecked after initial running-in
Ideal replacement during routine servicing or engine bay refresh
