(1) For all-season conditions, use SAE 75W-90 or ATF Dexron-II. For temperatures greater than 0°F (-18°C), use SAE 80W-90 or SAE 90. (2) Use SAE 75W-90. (3) For all-season conditions, use SAE 75W-90. If temperature is below 0°F (-18°C), use ATF Dexron-II. (4) On Navajo, use SAE 80W-90 or SAE 75W-90. On all other models, use SAE 75W-90 for all-season conditions, and SAE 80W-90 for temperatures greater than 50°F (10°C). (5) Specification is total fluid capacity of transaxle, not refill capacity after pan removal. (6) On 929, specification is total fluid capacity. On all other models, specification is the amount needed to refill transmission after pan removal. Mazda calls this "replacement fluid capacity" in their maintenance tables and "pan" (as opposed to "total") in their transmission section. (7) On Navajo, use SAE 90. On all other models, use SAE 90 for temperatures greater than 0°F (-18°C), and SAE 80W for temperatures less than 0°F (-18°C). (8) On Navajo, use Mercon ATF. On Protege, use SAE 90 for temperatures greater than 0°F (-18°C), and SAE 80W for temperatures less than 0°F (-18°C). On all other models, use SAE 75W-90 or ATF Dexron-II for all-season conditions, and SAE 80W-90 or SAE 90 for temperatures greater than 0°F (-18°C).

DRIVE BELT ADJUSTMENT (NEW BELT)

ENGINE COMPRESSION

Note. Compression Tester (49-F018-9A0) or equivalent must be used to test compression on RX7.

RX7

  1. Warm engine to normal operating temperature. Disconnect crank angle sensor connector. Hold throttle plate fully open. Remove both trailing spark plugs (the 2 top spark plugs). Connect Compression Tester (49-F018-9A0) to upper spark plug hole of front rotor housing.
  2. Crank engine for 5-10 seconds at specified cranking speed. Note the compression of the 3 combustion chambers. Repeat procedure at the rear rotor housing.

Except RX7

  1. Warm engine to normal operating temperature. Remove all spark plugs. On Navajo, use remote starter switch to crank engine (DO NOT crank engine with ignition switch). On all other models, disconnect ignition coil primary wire connector.
  2. On all models, hold throttle plate fully open. Crank engine at specified cranking speed.
