Engine Type:
The 1996 Millenia was offered with two primary engine options: a 2.5L V6 (a conventional design) and a 3.0L Miller-cycle V6.
Engine Code Conventional:
Likely the JE-ZE or similar designation for the 2.5L V6.
Engine Code Miller:
KL31 for the 3.0L Miller-cycle V6.
Horsepower Conventional:
Approximately 170-175 hp for the 2.5L V6.
Torque Conventional:
Approximately 190-195 lb-ft for the 2.5L V6.
Horsepower Miller:
Approximately 210 hp for the 3.0L Miller-cycle V6 (with supercharger).
Torque Miller:
Approximately 210-215 lb-ft for the 3.0L Miller-cycle V6 (with supercharger).
Injection Type:
Electronic Fuel Injection (EFI) for both engine variants.
Octane Rating:
Premium unleaded gasoline (91 octane or higher) typically recommended for optimal performance, especially for the Miller-cycle engine.
Oil Change Interval:
Typically every 5,000 miles or 6 months, whichever comes first (refer to manual for specific engine and oil type recommendations).
Air Filter Replacement:
Recommended replacement every 15,000-30,000 miles, or as needed based on driving conditions.
Spark Plug Replacement:
Intervals vary based on plug type; platinum or iridium plugs can last 60,000-100,000 miles, while standard plugs may be around 30,000 miles. Manual will specify.
Engine Oil Type:
API SG or SH classification, SAE 5W-30 or 10W-30 recommended. Manual will confirm exact viscosity and API rating.
Coolant Type:
Ethylene glycol-based coolant with corrosion inhibitors. Specific type and mix ratio (50/50) will be detailed in the manual.
Brake Fluid Type:
DOT 3 or DOT 4 brake fluid.
Engine Reliability Miller:
The Miller-cycle engine, while innovative, could be complex to service and some early versions experienced issues with oil consumption or supercharger belt wear.
Engine Reliability Conventional:
The conventional V6 is generally considered reliable, but common issues for this era include intake manifold gaskets, valve cover gaskets, and occasional transmission control module (TCM) issues.
Suspension Wear:
Components like sway bar links, bushings, and struts/shocks can wear over time, leading to noise and handling degradation.
Electrical Gremlins:
As with many vehicles of this age, minor electrical issues such as faulty window regulators, door lock actuators, or dashboard warning lights can occur.
