2017 Chevy Equinox 2.4L Ecotec Engine: Problems, Longevity, And Specs

By Nick Marchenko, PhD

The 2.4L Ecotec engine made its debut in 2006 and has since been upgraded multiple times by GM. The original version is the LE5, followed by the mild hybrid version known as the LAT. In 2010, GM introduced piston upgrades that increased compression and also switched to direct injection, resulting in the LAF RPO code. This direct injection version also had its own hybrid option and an option compatible with E85.

The GM 2.4L Ecotec engine has several advantages that make it a popular choice among small to mid-sized SUVs from GM. One of the key advantages of this engine is its fuel efficiency. With the introduction of direct injection in 2010, the engine's fuel efficiency was further improved, making it a great option for those looking for an economical vehicle. 

However, despite its upgrades, the Ecotec 2.4L engine from GM has been known to have problems. Timing failure and oil consumption are two of the most significant issues that have given this engine a notorious reputation.  

GM 2.4L Ecotec Engine Specs & Horsepower

This engine was produced at the Spring Hill Manufacturing plant in Tennessee from 2006 to 2019. It's a four-cylinder engine with an inline configuration, meaning all the cylinders are in a straight line. The engine block and cylinder head are made of lightweight aluminum.

This engine can run on gasoline and uses either sequential port fuel injection or direct fuel injection. It has four valves per cylinder and a double overhead camshaft layout. The bore is 88.0 mm (3.5 in) and the stroke is 98.0 mm (3.9 in), resulting in a displacement of 2,384 cc (145 cu in). It's a naturally aspirated, four-stroke engine with a compression ratio of either 10.4:1 or 11.2:1, depending on the model.

The GM 2.4L engine has a power output ranging from 164 to 182 horsepower (122 to 136 kW) at 6,200-6,700 rpm and a torque output ranging from 159 to 172 lb-ft (216 to 233 Nm) at 4,800-5,000 rpm. It weighs in at a reasonable weight and follows a 1-3-4-2 firing order.

The recommended engine oil weight is SAE 5W-30, and it has a capacity of 4.7 liters (5.0 quarts) with an oil filter. The recommended oil change interval is every 10,000 miles (15,000 km) or 12 months, whichever comes first.

This engine has been used in a variety of GM vehicles over the years, including the Chevrolet Cobalt SS, Chevrolet Malibu, Chevrolet Equinox, GMC Terrain, Pontiac G6, and Buick LaCrosse, just to name a few. It's a reliable engine with a good power output and fuel economy, making it a popular choice among car buyers.

Possible Problems with GM 2.4L Ecotec Engine

The GM 2.4L Ecotec engine is a popular choice for small to mid-sized SUVs from General Motors, including the Saturn Vue, Terrain, and Equinox. However, there are several issues that owners of this engine should be aware of.

Timing Failure

One of the most significant problems with the Ecotec 2.4L engine is timing failure. This issue is caused by a top bolt in one of the tensioners that loosens over time, creating slack in the timing chain. Eventually, the chain will jump teeth and cause the valves and piston to collide, resulting in catastrophic damage. It's essential to listen and check for scuffing on the chain if you suspect timing failure.

Oil Consumption

Oil consumption is another significant problem with the Ecotec 2.4L engine. The design of the piston rings allows excess oil to move past the piston and into the combustion chamber, where it is burned off. GM is facing numerous lawsuits due to this issue, which can lead to compression issues in the engine. It's important to check and top off your oil regularly to avoid running your engine out of oil.

Carbon Buildup

In 2010, GM upgraded the Ecotec 2.4L engine with piston upgrades and direct injection, which helps increase compression. However, direct injection engines are known for carbon buildup. While this is not as serious as timing or oil consumption issues, it can cause problems over time.

Oil Leaks

Many Ecotec 2.4L engine owners report problems with oil leaks. These leaks can occur in various areas, including the rear main seal, valve cover, head gasket, and oil pan gasket. It's crucial to keep an eye out for any oil leaks and address them promptly.

So to sum it up, the GM 2.4L Ecotec engine is a reliable option for small to mid-sized SUVs from General Motors. However, timing failure, oil consumption, carbon buildup, and oil leaks are all issues that owners should be aware of. Regular maintenance, including checking oil levels and addressing any oil leaks promptly, can help keep your engine running smoothly.

2017 Chevy Equinox 2.4L Engine Life Expectancy

The life expectancy of a 2017 Chevy Equinox with a 2.4L engine can vary depending on several factors, including maintenance, driving habits, and overall usage. However, with proper care and maintenance, it is not uncommon for this engine to last well over 200,000 miles.

Regular oil changes, filter replacements, and other routine maintenance tasks can help extend the life of the engine. Additionally, driving habits such as avoiding aggressive acceleration and braking can also help reduce wear and tear on the engine.

It's important to note that unexpected issues such as manufacturing defects or accidents can also impact the life expectancy of the engine. In general, following recommended maintenance schedules and driving habits can help ensure a long and healthy life for the 2017 Chevy Equinox 2.4L engine.

What Chevy Models Use the GM Ecotec 2.4L Engine?

These models may have variations of the engine with different codes, such as LE5 or LEA, but they are all part of the Ecotec 2.4L engine family. The Ecotec 2.4L engine is known for its fuel efficiency, reliability, and smooth performance, which is why it has been a popular choice for Chevy vehicles.

Is 2017 Chevy Equinox 2.4L a Good Engine?

The 2017 Chevy Equinox 2.4L engine has received generally positive reviews and is considered a good engine by many. It offers a good balance of power and fuel efficiency, with an output of 182 horsepower and 172 lb-ft of torque, while achieving an EPA estimated 21 mpg in the city and 31 mpg on the highway. The engine also benefits from GM's Ecotec technology, which provides improved fuel efficiency and reduced emissions.

The engine has also proven to be reliable and durable, with many owners reporting few issues or problems.
