The Mazda 626 Distributor Cap directs high-voltage energy to all the spark plugs from the ignition coil to ensure the engine starts firing in the correct sequence and runs smoothly. The Mazda component is sealed in a hard plastic shell that contains molded posts for each of the cylinders, and a rotor rotates below, sweeping contacts in order to conduct current at the precise point of need. The cap keeps the entire ignition system in step by ensuring that these components are not contaminated by dirt, heat, and splashed water. Simple single-post layouts were applied in early years of production, with some variations that might add a few additional posts to be able to have setups that could fire two plugs or use a wasted-spark design, although all styles obey the same principle of delivering voltages in a well-organized manner. The plastic can be cracked by heat, vibration, carbon tracks, or eroded terminals, which widen gaps so the Mazda will idle roughly, stall, backfire, squeal, or hard-start, which warns the Mazda owner that a replacement Distributor Cap is needed. Because rapid temperature changes between frozen air and hot engine parts cause damage to the plastic material, cold climates accelerate the damage. Seeping moisture outside the O-ring may find its way into the circuit, which will cause a short unless a wipe with a dry cloth or a spray of water can temporarily reinstate the spark. Due to its low cost and simple replacement, many drivers include the cap as part of routine maintenance; others even unscrew it as a basic anti-theft device that will prevent their Mazda from starting. Routine checking of this minor yet important Distributor Cap assists the 626 in remaining dependable and efficient.
