Despite its rather lengthy list of problems, the GM 3.6 V6 is known to be quite bulletproof. The v6 power plant is powerful and tech-laden. Its Achilles heel though has to do with its engine oil changes.
What year did GM fix the 3.6 engine?
By the 2012 model year, GM had made several changes to help address the timing chain issues the 3.6L engine was having. Although vehicles after the 2012 model year may still have timing chain problems, it is much less common than years past.
Does GM 3.6 have a timing belt or chain?
The timing chain system on the GM 3.6L uses 3 separate timing chains, a primary chain and two secondary chains. The primary chain affects the timing on both banks while each secondary chain only affects the timing on the cylinder head or bank it is on.
How much horsepower does a Chevy 3.6 VVT have?
Variable Valve Timing (VVT): variable valve timing, or cam phasing, helps the 3.6L V6 deliver optimal performance and efficiency, and reduced emissions.

Is the Chevy 3.6 L V6 a good engine? – Related Questions
Is a 3.6 L V6 fast?
3.6L Pentastar V6 Engine
The 3.6L Pentastar V6 includes a TorqueFlite eight-speed automatic transmission. The power provided by this engine allows you to go from 0-60 mph in 6.5 seconds. If you want to drive the SXT trim, you will speed up from 0-60 mph in 6.6 seconds.
Is V6 twin turbo better than v8?
V-6 engines have improved performance compared to V-8 engines, especially when timing acceleration properly because there’s less tendency to drift to the outer edge. However, you can lose a little bit of the power ceiling with the weight advantage.
How much horsepower does VVT add?
Furthermore, VVT also broadens the torque curve before the peak, and prevents horsepower from dropping off rapidly after the horsepower peak. “With variable valve timing, we typically see a 5-10 percent improvement in output at the ends of the torque and power curves,” Godbold says.
How much horsepower does a 3.6 L V6 24v VVT engine?
The 3.6 liter Pentastar engine is rated at 305 horsepower and 270 lb. -ft.
Is the 3.6 L V6 24v VVT a good engine?
The 3.6 L FCA Pentastar V6 Engine is an overwhelmingly durable and reliable engine. That’s why it’s been used in in more than ten million Chrysler, Dodge, and Jeep vehicles since 2010. With proper maintenance the 3.6L Pentastar engine can provide years of reliable service.
How much horsepower does a VVT-i have?
1.8L 4-Cylinder DOHC 16-Valve with Dual Variable Valve Timing with intelligence (VVT-i): This engine option delivers an impressive 132 hp and 128 lb-ft of torque.
What RPM does VVT kick in?
“On the dyno, we’ve noticed that once you exceed 380 pounds of open spring pressure, the VVT system starts losing control of the cam phasing at engine speeds above 5,000 rpm.
What GM cars have the 3.6 VVT engine?
GM Flint South began production of the 3.6-liter, V-6 engine with variable valve timing (VVT), which is used in the 2007 Cadillac CTS, SRX and STS; Saturn Outlook; GMC Acadia and slated for the 2008 Buick Enclave. The 3.6L, V-6 VVT is an all-aluminum, dual overhead camshaft engine with variable valve timing.
What are the disadvantages of VVT?

| Advantage: |
VVT improves torque delivery at low / medium speed; Variable lift and duration lift high rev power. |
| Disadvantage: |
More complex and expensive |
| Who use it ? |

Why do people delete VVT?
Eliminating the VVT system is required when swapping to a non-VVT camshaft. These cams offer higher valve lift and longer duration for more performance. A VVT delete kit removes the VVT components and replaces them with standard parts.
How long do VVT-i engines last?
The Dual VVT-i 4.0 V6 engine found in the 09+ models is smooth, quiet, and reliable with engine longevity easily reaching over 200,000 miles (320,000 km).
Why would you delete VVT?
If VVT does such a stellar job of providing the best of both worlds, why would one want to remove it? In two words: more power. As everything gets bigger and factory parts are replaced with non-stock pieces, the VVT system will struggle to accommodate higher-lift cams and stiffer valve springs.
What does VVT stand for?
Variable Valve Timing or VVT is the timing for which the valves open. The VVT system controls the duration for which the intake and the exhaust valves open and the incline of the lift. All this activity happens within the engine while it’s operating.
Which is better VVT vs CVT?
In answer to your question – VVT can certainly offer efficiency improvements. CVT incurs greater drivetrain losses than manual transmissions and so wouldn’t really be considered efficient. Lift is employed solely as a performance measure and so is also not something that would be considered efficient.
