Understanding the 2018 chevrolet equinox lt specs and Powertrain Options

The 2018 model year was a “clean sheet” redesign, making it roughly 400 pounds lighter than its predecessor. This weight reduction directly impacts the 2018 chevrolet equinox lt specs regarding performance and fuel economy. The LT trim was the mid-range sweet spot, often equipped with the most popular engine choices.

The 1.5L LYX Turbocharged Engine

The base engine for the LT trim is the 1.5L LYX Turbocharged Engine. This small but mighty four-cylinder produces 170 horsepower and 203 lb-ft of torque. It uses a small-diameter turbo to reduce lag, making it feel punchy in city traffic while maintaining high fuel efficiency on the highway.

This engine features a Direct injection high-pressure fuel pump mounted on top of the valve cover. This design allows for precise fuel metering but can lead to a “clicking” sound that is perfectly normal for this technology. Always ensure you use high-quality fuel to prevent carbon buildup on the intake valves.

The High-Performance 2.0L LTG Turbo

If your Equinox LT has the 2.0L engine, you are looking at a significant jump in power. This variant delivers 252 horsepower and 260 lb-ft of torque. It is the engine of choice for those who need to tow or enjoy a more spirited driving experience.

Unlike the base engine, the 2.0L is paired with the 9T50 9-speed automatic transmission. This gearbox provides smoother shifts and keeps the engine in its power band more effectively than the standard 6-speed. It is a robust unit but requires specific fluid service intervals to maintain longevity.

The 1.6L Turbo-Diesel Efficiency King

Rare but highly efficient, the 1.6L LH7 whisper diesel was also available on the LT trim. It produces 137 horsepower and a stout 240 lb-ft of torque. This engine is ideal for long-distance commuters who prioritize range over raw speed, often achieving over 39 MPG on the highway.

Maintenance and Fluid Capacities for the Equinox LT

Keeping up with fluids is the single best way to prevent expensive repairs. The 2018 chevrolet equinox lt specs for fluids are very specific, especially regarding the type of oil and transmission fluid used. Using the wrong specification can trigger a check engine light or cause internal wear.

For the 1.5L engine, the SAE 0W-20 engine oil capacity is exactly 4.2 quarts (4.0 liters) with a filter change. It is mandatory to use Dexos1 Gen 2 synthetic oil. This specific oil formulation prevents Low-Speed Pre-Ignition (LSPI), a condition that can damage turbocharged engines under high load.

• 1.5L Gas Engine: 4.2 Quarts 0W-20 Dexos1
• 2.0L Gas Engine: 5.0 Quarts 5W-30 Dexos1
• 1.6L Diesel Engine: 5.3 Quarts 5W-30 Dexos2
• Coolant: Dex-Cool (Orange) 50/50 Mix
• Brake Fluid: DOT 4 (Confirm on reservoir cap)

When performing an oil change, inspect the Variable Valve Timing solenoid for any signs of oil seepage. These solenoids control the timing of the valves to optimize power and economy. If they become clogged with dirty oil, you may experience a rough idle or a decrease in power.

Chassis, Suspension, and Wheel Specifications

The 2018 Equinox LT utilizes a MacPherson strut front suspension paired with a four-link independent rear setup. This configuration provides a car-like ride quality while being durable enough for light dirt roads or snowy commutes. If you hear a “clunk” over bumps, check the stabilizer bar end links first.

Steering is handled by an Electronic Power Steering rack. This system eliminates the need for a hydraulic pump and fluid, reducing maintenance. However, it relies heavily on a strong battery and alternator. If your steering feels heavy, test your battery voltage before assuming the rack has failed.

Wheel and Tire Data

The LT trim typically comes with 17-inch or 18-inch aluminum wheels. Knowing your 5x115mm wheel bolt pattern is essential if you plan on buying aftermarket wheels or a second set for winter tires. The center bore is 70.3mm, and the lug nuts should be torqued to 100 lb-ft (140 Nm).

When rotating tires, always check the tread depth evenly. If the inner edges are wearing faster than the outer edges, your alignment is likely out of spec. Because this vehicle uses a compact chassis, even small hits to potholes can knock the toe settings out of alignment.

Symptom-to-Cause Troubleshooting Matrix

DIYers often face specific challenges with modern turbocharged SUVs. Use the table below to help diagnose common issues based on the 2018 chevrolet equinox lt specs and known service patterns.

Symptom	Potential Cause	Action/Part Needed
Loss of power / Hissing sound	P0299 turbocharger underboost	Check charge air cooler pipes for cracks or loose clamps.
Rough idle / Stalling at stops	Carbon on Direct injection high-pressure fuel pump or injectors	Run a high-quality fuel system cleaner or perform a walnut blast.
Engine vibration at low speeds	Failing Variable Valve Timing solenoid	Clean or replace VVT solenoids and change oil.
Heavy steering / Warning light	Voltage drop to Electronic Power Steering rack	Test battery and clean ground connections on the frame.

Interior Dimensions and Towing Capabilities

One of the most important 2018 chevrolet equinox lt specs for families is interior volume. The redesign focused on maximizing rear-seat legroom. You get 39.9 inches of rear legroom, which is competitive with much larger SUVs. The cargo area offers 29.9 cubic feet with the seats up and 63.9 cubic feet with them folded flat.

Towing capacity varies wildly depending on the engine. The 1.5L turbo and the 1.6L diesel are rated for a modest 1,500 lbs. However, if you have the 2.0L engine with the factory tow package, your towing capacity jumps to 3,500 lbs. This is enough for a small utility trailer or a pair of jet skis.

1. 1.5L / 1.6L Towing: 1,500 lbs (680 kg)
2. 2.0L Towing: 3,500 lbs (1,588 kg)
3. Max Tongue Weight: 10% of total trailer weight
4. GCWR (2.0L): 7,694 lbs

Always use a trailer with working brakes if you are approaching the 3,500-lb limit. The Equinox is a light vehicle, and a heavy trailer can easily “push” the car during emergency braking maneuvers. Ensure your hitch is properly secured to the frame rails according to the 100 lb-ft torque spec for the mounting bolts.

Common Mechanical Issues and Troubleshooting

While the 2018 Equinox is generally reliable, certain issues appear frequently in high-mileage examples. One common complaint involves the PCV (Positive Crankcase Ventilation) system. In extremely cold climates, the PCV orifice in the intake manifold can freeze, leading to increased crankcase pressure and blown rear main seals.

If you notice oil spots under the vehicle after a cold snap, check the rear of the engine block. Keeping your Dexos1 Gen 2 synthetic oil fresh helps prevent the moisture buildup that leads to this freezing issue. Many DIYers install a “catch can” to help trap this moisture before it enters the intake tract.

Another area to watch is the 9T50 9-speed automatic transmission in the 2.0L models. Some owners report a “harsh” shift from 1st to 2nd gear. Often, this is a software issue that a dealership can resolve with a TCM (Transmission Control Module) re-flash. Before assuming the hardware is failing, check for any available technical service bulletins (TSBs).

Frequently Asked Questions About 2018 chevrolet equinox lt specs

What is the exact oil type for the 1.5L turbo?
