Engine Options:
Available with 3.2L V6 and 3.6L V6 engines. Some later models and specific trims might have offered variations.
3.2L V6 Horsepower:
Approx. 220 hp
3.6L V6 Horsepower:
Approx. 255-270 hp (depending on year and tune)
Fuel Delivery:
Multi-port fuel injection (MPFI).
Timing Mechanism:
Both 3.2L and 3.6L V6 engines utilize a timing chain system, not a belt. The manual correctly addresses timing belt *replacement* for vehicles that have them, but for the CTS itself, it's chains. The manual's mention of 'Timing Belt Replacement' and 'Timing Belt Service Procedures' might be a general inclusion for a wider range of manuals or a slight inaccuracy in the product description if referring strictly to the CTS's inherent design.
Transmission Options:
Typically paired with a 5-speed automatic transmission (e.g., 5L40-E). A manual transmission option might have been available on certain performance-oriented trims or specific markets.
Manual Transmission Availability:
Limited availability; primarily automatic transmissions were standard.
Automatic Transmission Features:
Driver Shift Control (manual shifting capability), performance algorithms.
NHTSA Front Impact Rating:
Generally performed well in NHTSA crash tests for its era, often achieving 4 or 5 stars for frontal impact. (Specific year ratings vary).
IIHS Crash Test Performance:
Good performance in IIHS tests, particularly in frontal offset crash tests for its generation.
Traction Control:
Standard.
Electronic Stability Control:
StabiliTrak (optional or standard depending on year/trim).
Airbags:
Front airbags, side curtain airbags (optional/standard depending on year/trim), front side-impact airbags.
Oil Change Interval:
Typically every 5,000-7,500 miles or 6 months, with synthetic oil recommended for optimal performance and protection. Consult the manual for specific oil type and viscosity based on engine and climate.
Transmission Fluid Change:
Recommended every 50,000-100,000 miles, depending on driving conditions. Use specified Dexron automatic transmission fluid (e.g., Dexron VI or equivalent specified by GM).
Engine Oil Type:
Typically Dexos 1 or equivalent synthetic oil, SAE 5W-30 or 5W-40 depending on engine and climate. Always verify with the manual or oil cap.
Coolant Type:
GM's orange silicate-free coolant (AF-DL2) or equivalent.
Common Problems V6 Engines:
Ignition coil failures, water pump leaks (especially on the 3.6L), timing chain guides and tensioners (3.6L, can lead to rattling noise and potential timing issues if neglected), throttle body issues, oil leaks from valve cover gaskets or oil pan gaskets.
Common Problems Transmission:
Potential issues with the 5-speed automatic transmission solenoids or torque converter clutch (TCC) engagement, especially with higher mileage. Regular fluid changes are critical.
Common Problems Suspension:
Worn suspension bushings, tie rod ends, and ball joints can lead to noise and imprecise steering. Strut mounts can also wear out.
Cadillac Legacy:
Cadillac, America's premium automobile manufacturer, known for luxury, comfort, and technological innovation since its founding in 1902.
First Generation Introduction:
The Cadillac CTS was introduced for the 2003 model year as a significant departure from Cadillac's traditional large sedan lineup, targeting a younger demographic and competing more directly with European luxury sedans. It was built on the GM Sigma platform.
Manufacturing Location:
Lansing, Michigan, USA.
