The Mazda Millenia Timing Belt is the precise connection between the crankshaft and the camshafts, ensuring the valve movement of the engine is perfectly aligned with the movement of the pistons to avoid devastating metal-to-metal contact. This Millenia Timing Belt is fastened around toothed crank and cam pulleys, and a spring-loaded tensioner and smooth idler keep the grip precisely needed to provide reliable valve timing, and no oily chains or bulky gears are needed. Drives made of steel were commonly applied in older engines in general, but Mazda chose the lighter belt as it threaded easily in an overhead-cam system, was near silent in operation, and saved weight and money. The original belts were made with flatter teeth and plain rubber, and were expected to last 30,000 miles, although developments in materials created curved-tooth designs, which can be strengthened with fiber and last a reliable 30,000 miles more, without adding any extra noise. Visual checks, nevertheless, are essential, as cracks, lost teeth, frayed cords, or fluid contamination indicate impending failure to the extent of stopping the Mazda engine immediately, and, in interference engines, allowing the pistons to strike the open valves. When installing a replacement Millenia Timing Belt, failing to reinstall the automatic tensioner, idler pulleys, and water pump would risk the next tear-down to replace a couple of cheap components. Buyers who install a second Timing Belt have the liberty to be at ease because the re-sharpened system will ensure the Mazda purrs on again.
