• Mazdas come in a variety of models, such as the 626 and Protogé. The company uses similar systems and materials for the different vehicles, allowing for universal specifications for the different aspects. The torque specifications used on the different bolts for Mazdas apply to drain plugs, spark plugs and lug nuts.
  
  

Drain Plugs

• The drain plugs on the Mazda operate with the oil pan and the automatic and manual transmissions. The oil drain plug uses 22 to 30 foot-pounds of torque. You should check the gasket and threads of the bolt before installing it in the vehicle. Replace the bolt and gasket if you notice any signs of damage. The automatic transmission uses 12 to 21 foot-pounds of torque on the drain plug and 71 to 88 inch-pounds of torque for the transmission pan bolts. The manual transmission uses 33 foot-pounds of torque on the fill plug and 29 foot-pounds on the drain plug.
  
  

Spark Plugs

• Spark plugs require 156 inch-pounds of torque when installing. Consult the owner's manual for the proper gap, and adjust the gap as necessary using a gap tool. The gap tool slides between the electrodes to adjust the gap. Replace the spark plug if the gap is too large. Check the spark plug wires for signs of damage. The connection between the plug and the wire should be solid without any signs of corrosion inside of the wire. Always work with one spark plug and wire at a time, so you do not confuse the position of the wire.
  
  

Wheels

• The lug nuts on Mazdas torque to between 65 and 87 foot-pounds of torque. You should hand-tigthen the lug nuts while the vehicle is raised off the ground, so you can apply the torque evenly. Torque using a torque wrench set to between 65 and 87 foot-pounds. Apply the torque in a star pattern to the lug nuts. Start with the lug nut on top, and proceed in a star pattern across the remaining lug nuts.
