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.

A loud ticking noise (hydraulic valve lifter noise) may be heard from the top of the engine, particularly when the engine is still cold. The noise may occur more frequently on higher mileage vehicles; Hydraulic valve lash adjusters may need to be replaced to correct this issue. Following the maintenance schedule for oil changes will also help prevent a recurrence of the noise.
If the engine will not crank when the vehicle is parked on an incline, the transmission linkage may need adjustment. Some diagnosis is required because this may also be caused by inhibitor switch failure. The inhibitor switch tells the computer that the transmission is in "Park" or "Neutral", and allows the engine to start. If the inhibitor switch has failed, it will need to be replaced along with the "manual plate". Our technicians recommend checking with Mazda for updated parts.
