4Ws System Calibration:
Specific procedures for diagnosing, repairing, and calibrating the optional 4-Wheel Steering (4WS) system.
Depth:
Comprehensive, covering everything from basic fluid checks and tire rotations to complex engine and transmission rebuilds, full electrical system diagnostics, and bodywork.
Oil Change Interval:
Every 5,000 miles (8,000 km) or 6 months, whichever comes first.
Oil Filter Replacement:
At every oil change.
Spark Plug Replacement:
Every 60,000 miles (96,000 km) or 4 years.
Timing Belt Replacement:
Every 60,000 miles (96,000 km) or 4 years. CRITICAL for KL-DE/ZE engines to prevent catastrophic damage.
Coolant Flush:
Every 30,000 miles (48,000 km) or 2 years.
Engine Oil Capacity:
4.5 US quarts (4.3 liters) with filter (for KL-DE V6)
Engine Oil Viscosity:
10W-30 API SG or SH recommended. 5W-30 for colder climates. Refer to manual for specific recommendations.
Coolant Type:
Mazda long-life coolant or equivalent ethylene glycol-based coolant (typically a 50/50 mix with distilled water).
Brake Fluid Type:
DOT 3 or DOT 4 (Check specific manual for exact Mazda recommendation)
Timing Belt Failure:
The KL-DE/ZE engines are interference engines. Timing belt failure results in catastrophic engine damage. Strict adherence to replacement intervals is paramount.
Vacuum Leaks:
Aging vacuum hoses and gaskets can lead to vacuum leaks, causing rough idle and performance issues.
Power Window Motors:
Common failure point for window regulators and motors, particularly on older vehicles.
Cv Axle Wear:
Front CV axles can wear out over time, especially with aggressive driving, leading to clicking noises during turns.
4Ws System Faults:
The 4-Wheel Steering system can develop faults with hydraulic leaks, sensor issues, or control unit problems, often indicated by warning lights.
Fuel Pump Reliability:
While generally reliable, some units may experience eventual failure, leading to no-start conditions.
Brand Focus:
Mazda has a long history of producing sporty and engaging vehicles, often characterized by their 'Jinba Ittai' (horse and rider as one) philosophy.
First Generation:
Mazda Luce/Cosmo (Japan only), shared platform with Ford Probe in North America.
Second Generation Ge:
Launched in 1991, redesigned with a focus on performance and refinement. Featured a unique chassis design and Mazda's first V6 engine for a mass-produced passenger car. Introduction of AWD and 4WS options.
Discontinuation:
Discontinued in 1997, largely replaced by the Mazda Xedos 6 / Mazda 626 Coupe (GF chassis) in some markets, and the Mazda RX-7 (FD chassis) as its spiritual successor in the performance coupe segment.
Assembly Location:
Hofu, Yamaguchi, Japan
Production Volumes:
Moderate production volumes, making it a less common sight today compared to mainstream sedans.
