Diagnostic Ports:
OBD-I or early OBD-II compliant diagnostic connectors, depending on specific market and year, for ECU communication. This manual would detail their wiring.
Oil Change:
Every 3,000-5,000 miles or 6 months, whichever comes first. Rotary engines are sensitive to oil quality and consumption.
Spark Plugs:
Refer to manual; typically replace apex seals and spark plugs as part of major engine overhauls. Spark plugs are interval-dependent based on type (e.g., platinum).
Coolant Flush:
Every 30,000 miles or 2 years.
Engine Oil:
API SG or higher, SAE 10W-30 or 10W-40 recommended. Check manual for specific viscosity based on ambient temperature and rotary-specific oil additives if used.
Transmission Fluid Mt:
GL-4 SAE 75W-90 Gear Oil (e.g., Mazda Manual Transmission Fluid 75W-90 or equivalent).
Differential Fluid:
GL-5 SAE 80W-90 Gear Oil.
Coolant:
Mazda FL22 or equivalent Long Life Coolant (50/50 mix with distilled water).
Vacuum Lines:
Degradation of rubber vacuum lines leading to boost leaks and rough running.
Oil Consumption:
Rotary engines naturally consume oil as part of their lubrication system; however, excessive consumption can indicate apex seal wear.
Emissions System:
Issues with air pump system, catalytic converter (especially on US models), and associated solenoids.
Electrical Connectors:
Corrosion or degradation of electrical connectors, particularly in humid environments or on neglected vehicles.
Mazda Rotary Legacy:
Continuation of Mazda's pioneering and unique commitment to rotary engine technology, tracing back to the Cosmo and RX series.
Fd Introduction:
Introduced in 1992 (for 1993 model year in Japan), the FD represented a significant redesign focusing on lighter weight, improved aerodynamics, and enhanced rotary performance. It was the third generation of the RX-7. This manual covers the second iteration of the FD chassis (often referred to as Series 7 in Japan).
Series Changes 94 95:
Minor updates for 1994-1995 models (USDM '94 and '95 models, Japanese Series 7 and early Series 8) included subtle ECU remapping for emissions and drivability, minor suspension tuning, and interior trim refinements. The core electrical architecture remained consistent.
