Mopar 2017 Ram 1500 36l V6 Cai Reviews

The 3.6L V6 Pentastar is a 3.6-liter half-dozen-cylinder gasoline engine introduced first at the New York Motorcar Show in 2009 for the 2011 model-year Chrysler, Dodge, and Jeep vehicles. This new V6 is one of the most technologically advanced engines to engagement, created past Chrysler. This V6 is used in popular vehicles around the earth such as the Contrivance Challenger, Jeep Cherokee, Jeep Wrangler, and Ram 1500. The 3.6L Pentastar V6 for 3 years in a row was among the height ten engines in the US marketplace. Let's take an in-depth await at the 3.6 Pentastar engine blueprint, its common issues, reliability, and longevity.

The new 3.6 V6 engine is 38% more powerful, consumes 11% less fuel, and 42 lbs (19 kg) lighter than its 3.5-liter predecessor. Information technology is also smaller in size: 94 mm shorter than the 3.7 and 34 mm than the 3.5 V6. The engine has a high-pressure level die-cast aluminum cylinder cake with a lx-caste Five angle between cylinder banks. Information technology has an open-deck design that saves material, lighter and cheaper to produce, and has cast atomic number 26 cylinder liners for increasing longevity. The engine cake is equipped with iii piston oil cooler jets. Each oil jet cools two pistons preventing detonations past managing heat. In that location are forged steel connecting rods, the nodular iron crankshaft, and bandage aluminum pistons with depression-friction rings and reduced brim area for less weight and friction. The engine uses a chain-driven, vane-blazon variable deportation oil pump. Engineers removed all brackets for the engine accessories. The alternator, air conditioner compressor, and belt tensioner are bolted to the engine cake. They are driven by a serpentine belt every bit well. This arrangement has significantly reduced the level of vibration and racket.

The three.6L Pentastar has sand-cast aluminum cylinder heads fabricated of T7 heat-treated aluminum. The cylinder head features four-valve per cylinder and dual overhead camshafts with roller finger followers with hydraulic lifters. The intake and frazzle camshafts are concatenation-driven (there is a carve up timing chain for each head). Timing chains are a "silent chain link" design. All four camshafts come up with torque-actuated phasers. The intake valve has a single-piece design and is made of forged heat-resistant (martensitic) steel; the intake valve diameter is 39 mm. The exhaust valves have a ii-piece blueprint with a forged austenitic head welded to a martensitic stem. The exhaust valve diameter is 30 mm. Cylinder heads feature high-flow intake and exhaust ports and an integrated exhaust manifold. On elevation of the engine, there is a lightweight composite intake manifold fitted with a 74 mm throttle torso and an electronically controlled multi-point port fuel injection system.

90% of maximum torque is achieved in the range of 1800-6350 rpm. Thus, the engine can provide fantabulous driving dynamics without requiring high-octane (premium gasoline). While Pentastar engines are not demanding on fuel quality and sufficiently simple to maintain, they feature first-class fuel efficiency, low emissions, and smooth operation. Pentastar V6 engines are pop both in the U.s.a. and beyond. They come across Federal Tier two BIN five emission requirements, Ultra-low Emissions Vehicle Two standards, and Euro6 standards. It is also designed to meet stringent future standards, including LEV III and PZEV California standards.

In 2016, FCA released an upgraded Pentastar engine family and a new version of the 3.6L V6 for the Jeep Grand Cherokee and Contrivance Durango. The revised engine now has a 2-stage variable valve elevator (VVL). The VVL system provides low and high valve lifts. Low-lift settings at low speeds save fuel (up to a 2.7% increase over the previous version), while high valve elevator turns on when ability is needed. Unfortunately, the manufacturer was forced to install a cooled frazzle gas recirculation (EGR) system. The modified engine also features a new plastic intake manifold with longer runners, increased torque, high-tumble intake ports within cylinder heads, new valve springs, and low-tension piston rings. The fuel arrangement received new eight-pigsty injectors. And the adept news is, the engine has kept a port fuel injection. The variable valve timing (VVT) system was recalibrated. The compression ratio was increased from 10.ii:1 to 11.3:1. These improvements assist to produce more ability and torque together with meliorate fuel efficiency and emissions.

In recent years, the Pentastar V6 engine successfully competes with the more technologically avant-garde ii.0L turbo four - 2.0-liter Turbo Hurricane.

3.vi V6 Pentastar Common Issues and Reliability

Is the iii.vi Pentastar a adept reliable engine? Well, this iii.half dozen-liter V6 has been around for a long fourth dimension (well-nigh xi years), and for a good reason. The three.6 Pentastar has high power for the V6 NA engine and is efficient and reliable. Notwithstanding, owners of these engines may face some mutual problems. Let's take a expect at these issues in this article beneath.

Pentastar 3.six cylinder caput failure. The left side cylinder head problem had been institute in about 0.5% percent of 2011-13 vehicles with three.6-liter V-six Pentastar engines. Engines with cylinder head failure can be easily recognized past a ticking audio from the left side. Sometimes they had other symptoms, including a check engine light illuminated, misfires, and ability loss. The failure was caused by excessive wear. In August 2012, Chrysler made the design upgrade. Revised heads come with hardened valve guides and seats, and the problem is rarely reported now. All 2011, 2012, and some 2013 model twelvemonth vehicles with 3.6L Pentastar engines have extended engine warranty on the left side cylinder caput to 10 years or 150,000 miles.

FCA 3.6L Pentastar rocker arm problems. Very frequently, this problem is confused with the one described above. The most common symptoms are very similar - a ticking/borer sound from the upper engine area and a cylinder misfire. You can also notice a diagnostic problem lawmaking (DTC) indicating misfire. To accost this upshot, the FCA issued a service message in March 2014. Nevertheless, some newer Pentastar 3.6 engines still experience rocker arm failure, and there are no whatsoever boosted warranty periods for this trouble from the FCA.

Cooling system problems and oil pump failure. Some owners complain of problems with chock-full-upwardly radiators and frequent replacement of water pumps, thermostats, oil cooler, and oil pumps. The trouble may lie in the production and training of an individual engine before assembly. The heads are sand-cast and undergo serious inspections for cleanliness before reaching associates plants. Only any residual sand that remains from the casting procedure inside the engine tin can also circulate through the vehicle'southward cooling systems, causing clogs in the radiator and oil cooling arrangement. Fortunately, this problem is not as common as the ones listed in a higher place, but it is very annoying since many stories on the internet from owners who went through these aforementioned repairs multiple times.

Summary

So, is the 3.6L Pentastar engine reliable? Summing upwards, we can say the Pentastar 3.6 reliability is mode higher up average. Information technology is time-tested well enough, and over 10 million Pentastar engines were produced to date. Despite that they had some issues early on on, the three.6L V6 Pentastar is bang-up, durable, 1 of the most reliable engines bachelor on the marketplace correct at present. With proper maintenance, the iii.half dozen Pentastar engine longevity is around 250-300k miles (there are even a few cases of the Pentastar last up to impressive 500,000 miles).
