Performance Characteristics:
Designed for economical and reliable everyday motoring, not high performance. Acceleration and top speed are modest by modern standards.
Carburetor Types:
Often equipped with single or twin SU carburetors (e.g., HS2, HS4) or Zenith-Stromberg carburetors. Specific model variants will dictate exact carburetor fitment.
Fuel Type:
Designed for leaded or low-lead petrol. Unleaded petrol may require an additive or hardened valve seats depending on engine modifications.
Engine Orientation:
Transverse, front-wheel drive configuration.
Cooling System Type:
Pressurized liquid cooling system with a radiator and fan.
Oil Change Interval:
Typically every 3,000-5,000 miles or 6-12 months, depending on usage. Consult the manual for specific recommendations.
Ignition Tune Up Interval:
Spark plugs, points (if applicable), and condenser inspection/replacement every 10,000-15,000 miles. Timing check as needed.
Fluid Check Interval:
Regular checks recommended at every refueling or at least monthly for coolant, brake fluid, and clutch fluid.
Engine Oil:
SAE 20W-50 or 20W-40 (API SF/CD or equivalent) is commonly recommended for the era. Consult manual for exact specifications and capacities.
Coolant:
Ethylene glycol-based antifreeze mixed with distilled water (50/50 ratio). Specific coolant types may be recommended in the manual.
Brake Fluid:
DOT 3 or DOT 4 hydraulic brake fluid (glycol-based). Ensure compatibility if replacing.
