Overall Length:
Approx. 150.7 inches (3827.8 mm) - varies slightly with bumper options
Overall Width:
Approx. 67.7 inches (1720 mm)
Overall Height:
Approx. 63.5 inches (1612.9 mm) - varies with top and tire size
Curb Weight:
Approx. 2800-3200 lbs (1270-1451 kg) - varies by configuration
Crash Test Data:
No formal crash test ratings from modern organizations due to the era of production. Design prioritizes off-road capability over occupant safety in high-speed impacts.
Braking System:
Hydraulic drum brakes on all four wheels. Later models may have offered optional front disc brakes.
Seatbelts:
Typically lap belts. Shoulder belts were not standard or commonly available for much of this production run.
Roll Over Protection:
Basic roll bar or hoop structure provided with some soft tops and hardtops. Not engineered to modern ROPS standards.
Engine Oil Change:
Typically every 3,000 miles or 6 months. Refer to specific year for exact recommendation.
Transmission Fluid Change:
Manual transmission fluid inspected at regular intervals, changed as needed or every 20,000-30,000 miles. Transfer case and differentials also require fluid checks and changes.
Tune Up Schedule:
Periodic spark plug replacement, ignition timing adjustments, and carburetor tuning were common.
Engine Oil:
API SG/SF service classification, SAE 10W-30 or 10W-40. For older engines with flat tappets, a high zinc content oil (ZDDP) is often recommended. Manual will specify exact viscosity based on temperature.
Transmission Fluid:
GL-4 gear oil, SAE 80W-90 for manual transmissions. Automatic transmission fluid (if equipped) would be Type A or Dexron.
Coolant:
Ethylene glycol-based antifreeze. 50/50 mix with distilled water. Capacity varies by engine, typically 10-12 quarts.
Engine Common Problems:
The Hurricane engine can be prone to oil consumption and head gasket issues. Overheating due to radiator efficiency and fan design can occur. Valve seat recession on unleaded fuel for earlier engines.
Transmission Common Problems:
Wear in synchronizers and bearings for manual transmissions. Transfer case chain stretch or wear.
Chassis Common Problems:
Frame rust, especially near spring mounts and outriggers. Bushing wear in suspension and steering components. Brake drum expansion and shoe scoring.
Electrical Common Problems:
Corrosion in wiring connectors, failing generator/alternator output, switch failures, and grounding issues.
Jeep Legacy:
Carries the renowned Jeep legacy of military-derived, rugged, and go-anywhere capability, tracing lineage back to the original Willys MB.
