Injection Type:
Sequential Multi-Port Fuel Injection (SFI)
Fuel Type:
Premium Unleaded Gasoline recommended
Coolant Type:
Dex-Cool (Orange) OAT antifreeze/coolant or equivalent meeting GM specification.
NHTSA Crash Test Ratings:
Generally good for its era, with 4 or 5 stars in frontal and side impact tests. Specific ratings should be verified for exact year/configuration.
Active Safety:
Anti-lock Braking System (ABS), Electronic Brake-force Distribution (EBD), Traction Control System (TCS), StabiliTrak (Electronic Stability Control).
Passive Safety:
Front airbags, front side-impact airbags, available roof-mounted side-curtain airbags, active head restraints (early models).
Oil Change Interval:
Typically every 7,500 miles or 12 months, or based on oil life monitoring system. Refer to manual for specific recommendations.
Air Filter Replacement:
Approximately every 30,000 miles or as needed based on inspection.
Spark Plug Replacement:
3.6L V6 (Iridium): ~100,000 miles. 4.6L V8 (Iridium/Platinum): ~100,000 miles. Refer to manual for exact specification and gap.
Transmission Fluid Service:
Recommended around 100,000 miles for both transmissions, but inspect condition. Specific procedures and fluid types are crucial and detailed in the manual.
Engine Oil Type:
SAE 5W-30 synthetic oil meeting GM Dexos1™ (or equivalent specification for the year, likely GM 4718M or 6094M for earlier models). Refer to manual for exact specification.
Engine Oil Capacity:
3.6L V6: Approx. 5.5 quarts (5.2L). 4.6L V8: Approx. 5.0 quarts (4.7L). (with filter change, refer to manual for exact capacity).
Common Problems V8:
Northstar engine specific issues like coolant leaks (intake manifold gaskets, oil cooler lines), oil consumption, and timing chain tensioner wear are potential concerns if not properly maintained.
Common Problems V6:
Timing chain issues (rattle on startup) can occur with the LY7/LLT engines if not maintained. Ignition coil failures and oil leaks (e.g., valve cover gaskets) are also noted.
Suspension Components:
Wear in suspension bushings, ball joints, and control arms can lead to noise and alignment issues. Air suspension components (if equipped) can be prone to leaks or compressor failure.
Electronics:
Various electrical glitches can occur, including issues with power windows, HVAC controls, and infotainment systems.
