Understanding the Power Behind the 2020 chevrolet equinox premier

The Premier trim often comes equipped with one of two forced-induction powerplants that define the driving experience. Most owners find themselves deciding between the fuel-efficient LYX 1.5L Turbocharged engine or the more robust 2.0L variant. Each engine has a unique personality and specific maintenance requirements that you must follow to ensure longevity.

If your vehicle features the LTG 2.0L Turbocharged engine, you have access to significantly more torque, making it ideal for light towing or highway passing. This engine is paired with the advanced Hydra-Matic 9T50 transmission, a nine-speed unit designed for smooth shifts. Understanding which powertrain sits under your hood is the first step in any DIY diagnostic process.

Both engines utilize Gasoline Direct Injection (GDI) technology to maximize power and efficiency. While effective, GDI systems rely heavily on a GDI high-pressure fuel pump that can be sensitive to fuel quality. Using high-quality Top Tier fuel helps prevent carbon buildup on the intake valves, a common issue in modern turbocharged crossovers.

The Benefits of the 2.0L Turbo Upgrade

Choosing the larger engine in the Premier trim provides a towing capacity of up to 3,500 pounds. This makes it a viable option for those who occasionally pull a small utility trailer or a pair of jet skis. When towing, always monitor your transmission temperatures to prevent premature wear on the internal clutches.

The 2.0L engine also benefits from a more aggressive cooling system compared to the base 1.5L model. If you notice the temperature needle creeping up during summer drives, check the coolant levels in the expansion tank immediately. Always use the specified Dex-Cool coolant to prevent internal corrosion and water pump failure.

Essential Fluids and the Dexos 1 Gen 2 Oil Specification

Oil is the lifeblood of any turbocharged engine, and the 2020 model year is particularly picky about what you pour into the crankcase. Chevrolet requires the Dexos 1 Gen 2 oil specification for both the 1.5L and 2.0L engines. This specific oil formula is designed to combat Low-Speed Pre-Ignition (LSPI), which can destroy pistons in small-displacement turbo engines.

Change your oil every 5,000 to 7,500 miles, regardless of what the Oil Life Monitor (OLM) suggests if you drive in harsh conditions. Frequent short trips, extreme heat, or dusty environments qualify as “severe service” in the eyes of a technician. Using a high-quality filter like an ACDelco unit ensures that contaminants stay out of your Variable Valve Timing solenoid.

When performing an oil change, inspect the drain plug gasket for cracks or flattening. A small leak at the plug can lead to a messy driveway and potentially low oil levels over time. Tighten the drain plug to the factory-specified torque to avoid stripping the threads in the aluminum oil pan.

Transmission and AWD System Maintenance

The 9-speed transmission in the Premier trim is a marvel of engineering, but it requires clean fluid to function correctly. While some manuals suggest “lifetime” fluid, experienced mechanics recommend a drain and fill every 45,000 to 60,000 miles. Fresh Dexron-VI fluid keeps the shifting crisp and prevents the “shudder” often reported in high-mileage units.

If your vehicle is equipped with All-Wheel Drive, do not forget the AWD torque transfer device located at the rear. This unit distributes power between the front and rear wheels based on traction needs. Changing the gear oil in the rear drive module and the power take-off unit is a great way to ensure winter-ready performance.

Common Troubleshooting: P0299 and EVAP Issues

Even a well-maintained 2020 chevrolet equinox premier can occasionally throw a check engine light. One of the most common codes for this generation is the P0299 turbocharger underboost code. This often indicates a leak in the charge air cooler pipes or a failing wastegate actuator on the turbo itself.

Before assuming the turbo is dead, inspect all rubber boots and plastic piping between the turbocharger and the intake manifold. A loose clamp or a small hairline crack can cause enough boost pressure loss to trigger the code. Tighten all clamps and look for oily residue, which often signals a boost leak location.

Another frequent culprit for a check engine light is the EVAP canister purge valve. If you experience a rough idle or the car struggles to start immediately after refueling, this valve is likely stuck open. It is a relatively inexpensive part and sits right on top of the engine, making it an easy DIY fix for most owners.

Diagnostic Decision Table

Symptom	Potential Cause	Action Step
Hard start after getting gas	Stuck EVAP Purge Valve	Replace purge valve (ACDelco)
Whining noise under acceleration	P0299 Underboost / Leak	Inspect turbo charge pipes
Rough idle / Stalling	Dirty VVT Solenoids	Clean or replace solenoids
Shudder during gear shifts	Old Transmission Fluid	Perform transmission fluid service

When diagnosing these issues, a basic OBD-II scanner is your best friend. Plug it into the port under the dashboard to pull the specific fault codes before you start buying parts. This saves time and ensures you are addressing the actual root cause of the problem.

DIY Maintenance: Spark Plugs and Air Filters

Replacing the spark plugs is a critical part of the 100,000-mile service, but many enthusiasts do it at 60,000 miles for better performance. The ACDelco 41-153 spark plugs are the factory-recommended choice for the 2.0L engine. Always check the gap before installation, even if the box says they are “pre-gapped” from the factory.

To access the plugs, you must remove the plastic engine cover and the individual ignition coils. Be gentle with the plastic clips on the wiring harness, as they can become brittle from engine heat. Use a spark plug socket with a rubber insert to prevent cracking the porcelain during the removal or installation process.

The engine air filter is another simple DIY task that significantly impacts fuel economy. A clogged filter restricts airflow to the turbocharger, forcing it to work harder and run hotter. Check the filter every 15,000 miles and replace it if you see significant dirt or debris trapped in the pleats.

Optimizing the Cabin Environment

Don’t forget the cabin air filter, which is located behind the glovebox. If you notice a musty smell when the AC is running, or if the blower motor seems weak, the filter is likely blocked. Replacing this filter every year ensures that you and your passengers are breathing clean, filtered air during long road trips.

This is helpful if you are deciding between keeping your current Premier or trading it in for an EV.

Safety Systems and Electronic Reliability

The 2020 chevrolet equinox premier is packed with safety sensors, including Forward Collision Alert and Lane Keep Assist. These systems rely on a camera mounted behind the rearview mirror and radar sensors in the front bumper. If you receive a “Service Driver Assist System” message, ensure the windshield is clean and the front grille is free of ice or mud.

Battery health is vital for these electronic systems to function correctly. A weak battery can cause “ghost” codes or flickering screens in the infotainment system. Most modern batteries last between three and five years; if yours is the original from 2020, it may be time for a proactive replacement.

When replacing the battery, ensure the terminals are clean and tight. Use a wire brush to remove any corrosion (the white powdery stuff) and apply a thin layer of terminal protector. A solid electrical connection prevents many of the common “no-start” issues reported by owners during cold winter months.

Tire Care and Alignment

The Premier trim usually sits on larger 18-inch or 19-inch wheels, which look great but can be expensive to wrap in new rubber. Rotate your tires every 7,500 miles to ensure even tread wear. If you notice the steering wheel is off-center or the car pulls to one side, get a professional four-wheel alignment.

Maintaining proper tire pressure is also essential for the AWD system. Significant differences in tire diameter (caused by uneven wear or incorrect pressure) can put extra stress on the center differential. Check your door jamb for the specific PSI requirements and adjust them when the tires are cold.
