⚙️ Engine Specifications
Primary Engine Options
Engine Variants:
Likely includes 2.2L F2 (SOHC and DOHC variants), and potentially the 1.8L F8 (early models) and 2.0L FE (later models for 626). MX-6 likely focused on the more powerful 2.2L DOHC turbo (F2T) and naturally aspirated 2.2L DOHC (F2).
Performance Data
Horsepower And Torque:
Specific figures vary by engine and trim. For example, the F2T engine typically produced around 145-164 horsepower and 170-190 lb-ft of torque. Naturally aspirated 2.2L DOHC engines produced around 110-140 hp. The manual will contain precise specifications for all variants.
Fuel System
Fuel Delivery:
Electronic Fuel Injection (EFI) for most models, including Sequential Multi-Port Fuel Injection (MPI). The manual will detail specific injector types, fuel pump pressures, and control module operation.
Engine Management
ECU Details:
Engine Control Unit (ECU) diagnostics, sensor data interpretation (e.g., MAP, TPS, O2, ECT sensors), and ignition timing control.
🔧 Transmission
Standard Transmission
Type:
Likely a 5-speed manual transmission for both 626 and MX-6, with specific gear ratios detailed in the manual.
Optional Transmission
Type:
4-speed automatic transmission likely available on most models, with detailed service and diagnostic procedures.
Features
Drive Type:
Front-wheel drive (FWD) is standard for both 626 and MX-6. All-wheel drive (AWD) was an option for some 626 models (GV chassis wagon).
Fluid Specifications
Manual Transmission Fluid:
Specific GL-4 or GL-5 gear oil, with viscosity grades like 75W-90 or 80W-90. Capacities will be listed.
Automatic Transmission Fluid:
Dexron II or equivalent, with specific capacities and change intervals detailed.
📐 Dimensions
