You want to know how many gallons a Jeep Grand Cherokee hold? Luckily, this vehicle has a tank capacity of up to 68 gallons, which is more than enough to carry all your essentials. Check the fuel tank capacity on the vehicle’s owner’s manual to find out the exact amount of gas it holds. Listed below are the different fuel capacities of Jeeps.
3.6-Litre V-6 Engine
The 3.6-litre V-6 engine in the Jeep Grand Cherokee was introduced in 2011. This is a new engine version that has been found on several other models since then. It offers an impressive 260 to 293 horsepower and a-speed automatic transmission. It is rated to provide an average of 19 mpg in the city and 26 mpg on the highway. Although the power of this engine is impressive, it does have some reliability problems.
One of the most common problems with the 3.6-litre engine was rocker arm failure. It led to a ticking sound, and the cylinder misfired. While the issue was fixed with a service bulletin, no additional warranty has been offered for the vehicle. Additionally, owners of the 3.6-litre engine also reported cooling system issues. The Jeeps overheated more than once, and owners had to replace the water pump and oil pump to prevent overheating.
For power, the 2020 Jeep Grand Cherokee lineup offers four different engines. The base 3.6-litre V6 engine has 290 horsepower and 257 pound-feet of torque. It also has Best-in-class towing capacity. You can choose the 5.7-litre V8 engine if you want a sturdier vehicle. A diesel engine is not recommended for this vehicle.
The 3.6-litre V-6 engine in the Jeep Grand Cherokee L is more refined than the other models. It serves torque early and throughout the engine’s power range. The Jeep Grand Cherokee L’s transmission also uses a pressure reserve element that provides dedicated transmission fluid at the engine’s restart to reduce transmission delay. The transmission can be pre-engaged when traffic moves.
5.7-Liter Hemi Engine
A 5.7-litre HEMI engine in the Jeep Grand Cherokee is a fantastic addition for anyone looking for the ultimate off-road car. It was a popular choice for muscle cars and was very popular on the street, drag strip, and track. It was one of the most popular engines on the market, so it was a natural choice to put one in a Jeep Grand Cherokee.
The Jeep Grand Cherokee has been a favoured platform for several decades now. Its solid chassis is sturdy enough to be a bridge girder if needed. The quiet ride of a Grand Cherokee isolates the occupants from the road realities. On the other hand, the power steering is very numb and does not feel natural on a slick surface.
The 4.7-litre HEMI V8 engine in the Jeep Grand Cherokee is another great option. It packs 235 horsepower and boasts excellent fuel economy. The 5.7-litre engine does not offer the same fuel economy as the 3.6-litre engine, but it does get 14 mpg in the city and 22 mpg on the highway. It is also available as an option on Limited, Trailhawk, Overland, and Summit 4×4 trim levels.
The 5.7-liter Hemi engine in the Jeep Grand Cherokee L is optional, but it is only available with a four-wheel drive. It delivers 357 horsepower and 390 lb-ft of torque and is paired with a ZF 8-speed automatic transmission. With a 5.7-litre Hemi V8, the Grand Cherokee L can tow up to 7,200 pounds.
4.7-Litre Straight-6 Engine
A 4.7-litre straight-6 engine in wranglers and Grand Cherokees is a popular choice, but not in every vehicle. The 4.0-liter was the entry-level engine until the third generation was introduced in 2005. A 3.7-litre Powertech V6 replaced that model. When emissions regulations caused Chrysler to cancel 4.0 production, the 4.0 was replaced by the 3.7L Powertech V6.
The 4.7-litre straight-6 engine in wranglers and Cherokees is the best-performing Jeep brand, but the newest generation has issues with it. Jeep recalled EcoDiesel engines in recent years because they could fail to regulate exhaust gas pressure properly. Some EcoDiesel-equipped vehicles were prone to problems with the cam gear, leading to catastrophic engine failure. But FCA has promised to replace the EcoDiesel engine with a new and improved 3.0-litre V6 in 2020.
While the 4.7-litre V8 engine in a Jeep Grand Cherokee isn’t as efficient as the 5.7-litre V8, it does accelerate the Jeep smoothly and sounds refined. It produces 260 horsepower and 330 lb-ft of torque at 5100 rpm, compared to 295 hp and 400 N*m for the standard 4.7-litre engine in a Jeep Cherokee.
The 4.7-litre engine in a Jeep Grand Cherokee is susceptible to oil foam. This is a symptom of a faulty PCV valve designed to vent out any excess condensation. If you notice this issue, take your Jeep to a mechanic for diagnosis. It may be a simple oil change, but if you notice oil foam inside, the next step is to replace the PCV.

3.7-Litre Straight-6 Engine
The 3.7-litre straight-6 engine in the Jeep Grand Cherokee offers a durable and efficient base engine. This engine produces 210 horsepower and 235 lb-ft of torque at 4000 pm. It replaced a previous 4.0-litre I-6 engine in the Jeep Liberty and was refined to deliver smooth V-6 power without compromising economy.
The 3.8-litre Pentastar V6 engine is one of the most advanced engines in the history of FCA. This engine delivers better horsepower and torque than other engines in its class. The torque curve is flat and broad, with 90 per cent of its peak torque available between 1,800 and 6350 pm. The 3.7-litre straight-6 engine in the Jeep Grand Cherokee is more than capable of handling challenging terrain.
The 3.7-litre straight-6 engine has a new cylinder head that features a modified cam profile. It also features new valve lash adjusters and a composite manifold. It has a higher compression ratio at 9.7 lbs/cubic inch. The valve cover is also made from a plastic-like composite material and features 21 grommets to prevent vibrations from causing damage to components and ignition coils.
The new WJ 1999 Grand Cherokee was redesigned in September 1998 and shared the same 127-parts as its predecessor, WJ. The rear tailgate glass opened independently from the ZJ 1998 model. PowerTech was a new engine that replaced the pushrodV8 engine. It produced less torque but was more fuel-efficient than the pushrods, which were notoriously heavy. Another update to the straight-six engine was a redesigned intake manifold that gave it an additional ten horsepower.
4.0 Straight-6 Engine
A 4.0-litre inline-six-cylinder is the base engine in the Jeep Grand Cherokee. This engine has 210 horsepower and is more fuel-efficient than a 4.7-litre V-8. This engine is known for its durability and typically lasts between 150-300,000 miles before needing replacement. Jeep Grand Cherokees come standard with rear-wheel drive. However, the Grand Cherokee also comes with a three-wheel-drive system.
The cylinder head on the 1995-2000 Jeep Grand Cherokee engine underwent only minor changes. A stud girdle and more webbing were added to the engine block to improve its rigidity, especially the main crankshaft bearings. In 1998, the cylinder head changed from a high-flow design to a lower-flowing design. In 1999, the 4.0-litre engine was given the Power Tech name and carried over to all other Jeep models.
While the 4.0-litre engine was not made in North America after 2006, the XJ Jeep Cherokee is still produced in slightly modified form with a 2.5-litre I-4 engine. It produced 190 horsepower at 4600 rpm and 235 lb-ft (312 N*m) of torque. This was the quickest engine Chrysler produced and gave Jeeps the capability of attaining over 25mpg.
The 4.0-litre engine is considered the best off-road engine in the Jeep Grand Cherokee. The 4.0L engine is famous for its low-end torque, making it ideal for rock crawling and trailing. In addition, the 4.0-litre engine has a fuel injection system, making it easy to modify the engine to improve performance. The engine is a highly versatile vehicle that allows the owner to do almost anything.
