Quinton Hazell QTT332 Timing Belt Tensioner Pulley

Replacement Quinton Hazell timing belt tensioner pulley for Mazda MX-5 MK1/NA and MK2/NB/NB-FL 1.6 and 1.8 petrol models, including the 1.8i Turbo, as listed in the compatibility table.

The timing belt tensioner pulley helps maintain the correct timing-belt tension as the belt runs around the crankshaft and camshaft pulleys. QTT332 is designed as an aftermarket replacement for the original component.

A worn tensioner bearing can develop noise, roughness or excessive play and may affect timing-belt tracking and tension. Because access requires removal of the timing covers and timing belt, the tensioner is commonly renewed as part of a complete timing-belt service.
