🛡️ Safety Features

Crash Test Info:

Specific NHTSA/IIHS ratings for this era are scarce, but the chassis design emphasized driver safety with a reinforced cabin. The manual will contain body integrity and structural repair data.

Braking System:

Four-wheel disc brakes. Turbo II models typically featured larger ventilated discs and optional Anti-lock Braking System (ABS).

Suspension Design:

Independent front and rear suspension, contributing to handling and stability.

Seat Belts:

Three-point inertia-reel seatbelts.

Vehicle Systems Integration:

Basic vehicle systems are electronically managed by the ECU. Manual details wiring diagrams for all electrical components.

🔧 Maintenance

Oil Change Interval:

Typically every 3,000-5,000 miles or 3-6 months. Rotary engines require specific oil types and monitoring. Manual will detail precise intervals and conditions.

Spark Plug Replacement:

Intervals vary by plug type and usage, but typically between 15,000-30,000 miles. The RX-7 uses multiple spark plugs per rotor. Manual will specify correct types and intervals.

Timing Belt Inspection:

Rotary engines do not have a traditional timing belt; they utilize an eccentric shaft. However, accessory drive belts require regular inspection and replacement. Manual will detail accessory belt tensioning and replacement.

Engine Oil Type:

Rotary engines have specific oil requirements. Typically a high-quality synthetic or semi-synthetic oil with a viscosity like 10W-30 or 10W-40. Crucially, the manual will specify oil meeting Mazda's rotary engine oil specifications (e.g., for lubrication and cooling of rotor seals). An oil metering injection system also requires specific oil.

Coolant Type:

Ethylene Glycol based coolant (e.g., 50/50 mix with distilled water). Manual will specify capacity and correct mixture.

Brake Fluid Type:

DOT 3 or DOT 4 brake fluid. Manual will specify type and flush intervals.

Rotary Engine Apex Seals:

Wear and failure of apex seals is a known concern for rotary engines if not maintained properly or if subjected to abuse. The manual is critical for understanding proper operating temperatures and rebuild procedures.

Oil Consumption:

Rotary engines inherently consume some oil for lubrication. The manual will detail normal consumption rates and how to monitor the oil metering system.

Turbocharger Reliability Turbo Ii:

Turbocharger systems can be sensitive to maintenance. The manual will guide on turbocharger inspections, maintenance, and common failure symptoms.

📚 Vehicle History
