G3,G4 Timing Belt Tensioner Pulley

This high-quality timing belt tensioner pulley is a direct replacement for the original unit fitted to a range of Volkswagen petrol engines from the early 1990s through to the late 1990s. Designed to maintain the correct tension on the timing belt, this pulley ensures smooth and accurate rotation of the belt, preserving essential valve timing and protecting the engine from premature wear or catastrophic failure.

The tensioner pulley works by guiding and stabilising the timing belt as it travels around the crankshaft, camshaft and auxiliary pulleys. Its precision-machined bearing allows the belt to run quietly and with minimal resistance, preventing slippage and ensuring the camshaft and crankshaft remain perfectly synchronised. A worn or noisy tensioner can lead to belt misalignment, excessive belt wear, or in severe cases, loss of engine timing.

This replacement unit features a 24mm width and 66mm outer diameter, matching original VW specifications for a perfect fit. The pulley is manufactured using high-grade materials and sealed bearing construction to deliver long service life and consistent operation under engine heat and load.

We strongly recommend replacing the tensioner pulley whenever fitting a new timing belt. For best results, inspect the timing belt idler, water pump and belt covers at the same time, as worn companion parts can shorten belt life or affect tension accuracy.
