Understanding Your 2020 chevrolet equinox engine Options

Chevrolet offered two main gasoline engines for the 2020 model year, both utilizing turbocharging to maximize displacement efficiency. The standard offering is the 1.5L LYX Turbocharged Inline-4, which focuses heavily on fuel economy for the average commuter.

For those who need more “get-up-and-go,” the 2.0L LTG Turbocharged Inline-4 was the premium choice. This engine significantly increases horsepower and torque, making it much better suited for towing or heavy highway use. It is worth noting that 2020 was the final year the 2.0L was available in this generation, making it a sought-after option for enthusiasts.

The 1.5L LYX Turbocharged Inline-4

The 1.5L LYX engine produces approximately 170 horsepower and 203 lb-ft of torque. It uses a small, quick-spooling turbocharger to provide low-end torque, which helps the vehicle feel responsive in stop-and-go city traffic. This engine is typically paired with a 6-speed automatic transmission.

Efficiency is the primary goal here, with direct injection technology helping to squeeze every bit of energy out of the fuel. However, like many small-displacement turbo engines, it works harder under load. This means that keeping up with the 2020 chevrolet equinox engine maintenance schedule is non-negotiable for long-term health.

The 2.0L LTG Turbocharged Inline-4

Stepping up to the 2.0L LTG engine provides a substantial boost to 252 horsepower and 260 lb-ft of torque. This engine is paired with a more modern 9-speed automatic transmission, which allows for smoother power delivery and better highway cruising. It makes the Equinox feel much more capable during passing maneuvers.

The LTG engine is a robust design used across several GM platforms, but it does run hotter than the 1.5L. Owners should pay close attention to the cooling system and oil quality. The extra power also means more stress on the Turbocharger Wastegate Actuator, a component we will discuss in the troubleshooting section.

Essential Maintenance for Peak Performance

Maintaining a 2020 chevrolet equinox engine requires a “safety-first” and precision-focused approach. Because both engines are turbocharged and direct-injected, they are sensitive to oil quality and filtration. Using the wrong products can lead to premature wear or catastrophic failure.

Always perform maintenance on a level surface with the engine cool to the touch. If you are lifting the vehicle, use high-quality jack stands and never rely solely on a floor jack. Wear nitrile gloves to protect your skin from used oil, which can contain harmful contaminants.

Oil Requirements and the Dexos Standard

GM mandates the use of Dexos 1 Gen 2 0W-20 Synthetic Oil for these engines. This specific oil formulation is designed to prevent Low-Speed Pre-Ignition (LSPI), a condition that can crack pistons in small turbocharged engines. Never substitute this with conventional oil or a non-Dexos certified brand.

Change your oil every 5,000 to 7,500 miles, regardless of what the “Oil Life Monitor” says if you do a lot of city driving. Frequent oil changes help flush out contaminants that can clog the Positive Crankcase Ventilation Orifice. A clean PCV system is vital for preventing oil leaks and maintaining proper crankcase pressure.

Air Filtration and Breathing

A clean air filter is the first line of defense for your turbocharger. Dust and debris passing through a torn or dirty filter can “sandblast” the turbo compressor blades, leading to a loss of boost. Fortunately, replacing the air filter is a simple DIY task that takes less than ten minutes.

Check the air box every time you change your oil. If you live in a dusty environment or drive on gravel roads, you may need to replace it more frequently than the manual suggests. A restricted filter will also decrease your fuel economy and put unnecessary strain on the 2020 chevrolet equinox engine.

Common Problems and Troubleshooting

While generally reliable, the 2020 chevrolet equinox engine has a few known “quirks” that owners should watch for. Most of these issues stem from the nature of direct injection and turbocharging. Early detection can save you thousands in labor costs at the dealership.

If you notice a sudden drop in power or a “limp mode” warning, pull over safely. Continuing to drive a turbocharged engine with a major fault can cause secondary damage to the catalytic converter or the engine internals. Always use an OBD-II scanner to pull codes before throwing parts at a problem.

Diagnostic Symptom Matrix

Use the table below to identify common engine behaviors and their likely causes.

Symptom	Potential Root Cause	Recommended Action
Loss of boost / Underboost code	Turbocharger Wastegate Actuator	Inspect linkage and vacuum lines.
Rough idle / Hesitation	Direct Injection Carbon Buildup	Perform an intake valve cleaning service.
Random Misfires (P0300)	Faulty Spark Plugs or Coil Packs	Check plugs for fouling or wide gaps.
Coolant Temperature Fluctuations	Engine Coolant Temperature Sensor	Test sensor resistance or check for leaks.
Whining sound under acceleration	Turbocharger Bearing Wear	Check for shaft play in the turbo.

The Challenge of Direct Injection Carbon Buildup

In a direct-injection engine, fuel is sprayed directly into the combustion chamber rather than over the intake valves. This means the valves are never “washed” by gasoline, leading to Direct Injection Carbon Buildup over time. This buildup can restrict airflow and cause rough idling or poor fuel economy.

To mitigate this, use high-quality Top Tier gasoline and occasionally use a specialized intake spray cleaner designed for DI engines. If the buildup becomes severe, a professional “walnut blasting” service may be required to restore performance. Keeping the Variable Valve Timing Solenoid clean through regular oil changes also helps maintain proper valve timing and combustion.

Handling the P0299 Turbocharger Underboost Code

One of the more common codes for the 2020 chevrolet equinox engine is the P0299 Turbocharger Underboost condition. This often points to a failing Turbocharger Wastegate Actuator or a leak in the charge air cooler (intercooler) piping. You might notice the car feels sluggish, especially when trying to climb hills.

Check all rubber boots and plastic pipes leading from the turbo to the engine. Even a small crack can cause a significant loss of pressure. If the pipes are secure, the wastegate itself might be sticking due to heat cycling and corrosion. Replacing the actuator is often cheaper than replacing the entire turbocharger assembly.

DIY Diagnostics and Repair Tips

If your “Check Engine” light comes on, don’t panic. Many issues with the 2020 chevrolet equinox engine are related to sensors that are relatively easy to access. For example, a failing High Pressure Fuel Pump might cause long cranking times or a stutter under heavy load.

Always start with the basics: check your battery voltage and ensure your gas cap is tight. If you encounter a code related to misfires, you may be fixing random misfires by simply replacing a set of worn spark plugs. Use only the OE-recommended Iridium plugs for the best results.

Testing the Engine Coolant Temperature Sensor

The Engine Coolant Temperature Sensor tells the ECU how much fuel to deliver based on engine heat. If this sensor fails, the engine might think it is perpetually cold, leading to a rich fuel mixture and poor MPG. You can test this sensor using a multimeter to check for proper resistance levels as the engine warms up.

If the sensor is faulty, replacing it is straightforward. Ensure the engine is completely cold before opening the cooling system to avoid steam burns. Have a catch pan ready for the small amount of coolant that will escape when you pull the old sensor out of the block.

Inspecting the PCV System

The Positive Crankcase Ventilation Orifice on these engines is a small but critical part. If it becomes clogged with oil sludge, crankcase pressure will build up and eventually blow out your main seals. This is a common issue in colder climates where moisture can freeze inside the PCV lines.

Periodically remove the PCV hoses and check for “milky” residue or thick sludge. Cleaning these lines with a bit of brake cleaner can prevent a much larger repair bill down the road. It is a simple piece of preventative maintenance that many owners overlook.

Frequently Asked Questions About 2020 chevrolet equinox engine

What is the best oil for the 2020 Chevy Equinox engine?

You must use a full synthetic oil that meets the Dexos 1 Gen 2 (or the newer Gen 3) specification. For both the 1.5L and 2.0L engines, 0W-20 is the standard weight. This oil is specifically formulated to protect turbocharged engines from heat and pre-ignition issues.

How often should I change the spark plugs?

While the manual may suggest a longer interval, most experts recommend checking or replacing spark plugs every 60,000 miles on turbocharged engines. The high cylinder pressures in the 2020 chevrolet equinox engine can wear down the electrodes faster than in a naturally aspirated vehicle.

Why is my Equinox losing power on the highway?

This is often caused by a P0299 Turbocharger Underboost condition. It could be a simple loose hose on the intercooler or a failing wastegate actuator. If the “Check Engine” light is flashing, pull over immediately, as this indicates a severe misfire that could damage the engine.

Does the 2020 Equinox have a timing belt or chain?

Both the 1.5L LYX and 2.0L LTG engines use a timing chain. Unlike timing belts, chains are designed to last the life of the engine. However, they rely on clean engine oil for lubrication and tensioner operation, making regular oil changes even more critical.

Can I use regular 87 octane fuel?

The 1.5L engine is designed to run on 87 octane. However, for the 2.0L LTG engine, premium fuel (91 or 93 octane) is highly recommended for maximum performance and to prevent “knock” under heavy load. If you hear a metallic pinging sound while accelerating, switch to a higher octane fuel.

Final Thoughts for Owners and DIYers

The 2020 chevrolet equinox engine is a sophisticated piece of machinery that rewards proactive owners. By sticking to high-quality synthetic oils and keeping an eye on the turbocharger system, you can enjoy many years of reliable service.
