The cooling fan module can fail causing the fan to either run constantly, or not operate at all. If the fan runs continuously, the engine may not warm up properly, and if the fan does not run, the engine may overheat. Mazda has a voluntary recall on model years 2002-2003 to address this concern.

If the engine cranks but won't start, the fault may be internal to the distributor. Diagnosis will show no spark and trouble codes for the crankshaft position sensor (CKP) or the camshaft position sensor (CMP). Our technicians recommend replacement of the complete distributor assembly if these conditions occur.
If a rumbling noise is heard from the engine, along with a possible loss in power, it may be caused by a collapsed hydraulic timing belt tensioner creating excessive cam backlash. Our technicians recommend replacing the timing belt and water pump at the same time, if they have not been recently replaced.
