G3 Timing Belt Tensioner Pulley - 1.4-1.6

This timing belt tensioner pulley is a direct replacement for a wide range of Volkswagen petrol engines, maintaining correct belt tension to ensure accurate valve timing and reliable engine operation.

The tensioner pulley applies controlled pressure to the timing belt, compensating for belt stretch and thermal expansion as the engine heats and cools. Correct belt tension is critical—too loose and the belt can jump teeth, too tight and it can overload bearings and shorten belt life.

Over time, tensioner pulleys commonly fail due to bearing wear, noise, rough rotation, or seizure. A worn or noisy pulley can quickly destroy a new timing belt, leading to loss of valve timing and potential engine damage. Replacing the tensioner pulley whenever the timing belt is changed is essential preventative maintenance.

Fitting notes: Always replace the tensioner pulley as part of a timing belt service. Inspect the timing belt, idler pulleys (if fitted), and water pump at the same time. Ensure the pulley rotates smoothly before fitting and follow the correct belt tensioning procedure for your engine.
