Engine Options and Powertrain Performance
The 2020 model year was significant for the Blazer because it introduced a new middle-ground engine option. This allowed buyers to balance fuel efficiency with the power needed for daily commuting and light hauling.
The 2.5L EcoTec Inline-4
The base engine is a 2.5L four-cylinder designed for efficiency. It produces 193 horsepower and 188 lb-ft of torque, making it a solid choice for city driving and urban environments where fuel economy is a priority.
This engine utilizes Direct Injection and Variable Valve Timing (VVT) to maximize every drop of fuel. It is paired exclusively with a 9-speed automatic transmission and is only available in Front-Wheel Drive (FWD) configurations.
The 2.0L Turbocharged Inline-4
New for 2020, the 2.0L Turbo engine offers a punchier experience. It delivers 230 horsepower and a robust 258 lb-ft of torque, providing better merging power on highways than the base engine.
This powerplant is available with both FWD and All-Wheel Drive (AWD). It is an excellent middle ground for drivers who want the turbocharged kick without the fuel consumption of a larger V6 engine.
The 3.6L V6 Powerhouse
For those who need maximum capability, the 3.6L V6 is the engine of choice. Standard on the RS and Premier trims, it pumps out 308 horsepower and 269 lb-ft of torque.
This engine turns the Blazer into a truly capable machine, especially when paired with the Advanced AWD system. It provides the necessary grunt for overtaking and is the only engine that unlocks the maximum towing potential of the vehicle.
2020 chevrolet blazer specifications for Towing and Hauling
Understanding the 2020 chevrolet blazer specifications for towing is vital if you plan on taking a boat to the lake or a small trailer to the campsite. Towing capacities vary significantly based on the engine and equipment.
The base 2.5L and the 2.0L Turbo engines are limited to a 1,500-pound towing capacity. This is sufficient for a small utility trailer or a couple of jet skis, but not much more.
To reach the 4,500-pound maximum, you must have the 3.6L V6 engine and the V92 Trailering Package. This package includes a heavy-duty cooling system to prevent the transmission from overheating under heavy loads.
- Maximum Towing (V6 with Tow Package): 4,500 lbs
- Maximum Towing (Standard): 1,500 lbs
- Payload Capacity: Approximately 1,400 to 1,600 lbs depending on trim
- Curb Weight: 3,700 to 4,300 lbs
Always remember to check your hitch rating and use safety chains properly. If you are towing near the limit, consider installing an electronic brake controller for added safety on steep descents.
Drivetrain and Chassis Details
The Blazer’s architecture is shared with the GMC Acadia and Cadillac XT5, but it is tuned for a more “sporty” feel. This is evident in the suspension geometry and the available AWD systems.
Transmission and Gearing
Every 2020 Blazer comes equipped with a 9T65 9-speed automatic transmission. This transmission is designed for smooth shifts and keeps the engine in its power band for better acceleration and efficiency.
For DIYers, it is important to note that this is a “filled-for-life” style unit, but heavy towers should still consider fluid changes at 45,000-mile intervals. Use only Dexron VI or the updated Dexron ULV fluid as specified by the manual.
AWD vs. Advanced Twin-Clutch AWD
The standard AWD system can disconnect the rear axle to save fuel when extra traction isn’t needed. However, the RS trim features a more sophisticated Twin-Clutch AWD system.
This advanced system can independently direct torque to the left or right rear wheel. This improves cornering on dry pavement and provides superior grip in snowy or muddy conditions by acting like a limited-slip differential.
Suspension and Braking
The front suspension uses a MacPherson strut design, while the rear features an independent five-link setup. This configuration allows the Blazer to handle more like a sedan than a traditional truck-based SUV.
Braking is handled by four-wheel disc brakes with Duralife rotors. These rotors are specially hardened to resist rust and corrosion, which is a major benefit for those living in the salt belt.
Exterior and Interior Dimensions
Knowing the physical footprint of the vehicle is essential for garage fitment and cargo planning. The 2020 Blazer is classified as a mid-size SUV, sitting between the Equinox and the Traverse.
Exterior Measurements
The Blazer has a wide stance, which contributes to its aggressive look and stable handling. The total length is 191.4 inches, with a 112.7-inch wheelbase.
The width (without mirrors) is 76.7 inches, and the height is 67.0 inches. These 2020 chevrolet blazer specifications make it slightly wider than many competitors, offering a more planted feel on the highway.
Interior Space and Cargo
Inside, the Blazer offers seating for five adults. The rear seat is mounted on rails, allowing it to slide forward or backward to prioritize either legroom or cargo space.
With the rear seats up, you have 30.5 cubic feet of storage. Folding the 60/40 split-bench seats flat expands that capacity to 64.2 cubic feet. This is plenty of room for camping gear, mountain bikes, or a large grocery haul.
- Front Legroom: 41.0 inches
- Rear Legroom: 39.6 inches
- Front Headroom: 39.8 inches
- Rear Headroom: 38.6 inches
DIY Maintenance and Fluid Capacities
For the weekend mechanic, having the right fluid types and capacities is the difference between a successful Saturday and a trip to the parts store. Always use a high-quality torque wrench when performing wheel or engine work.
Oil and Filter Specs
The oil type depends entirely on which engine is under the hood. For the 2.5L and 3.6L engines, use 5W-30 full synthetic oil. The 2.0L Turbo engine requires 0W-20 full synthetic oil.
The 2.5L engine takes 5.0 quarts, the 2.0L Turbo takes 5.3 quarts, and the 3.6L V6 requires 6.0 quarts. Always replace the oil filter (typically an AC Delco PF63 or equivalent) at every change.
Critical Fluid Capacities
Coolant is another vital area. The Blazer uses Dex-Cool (orange) coolant. Never mix this with traditional green coolant, as it can cause “sludging” and clog your heater core or radiator.
The cooling system capacity is roughly 10.1 to 12.5 quarts depending on the engine and towing package. For brake fluid, use DOT 3 from a fresh, sealed container to prevent moisture contamination.
Wheel and Tire Maintenance
Wheel sizes range from 18-inch on the L and LT trims to 21-inch on the RS. When rotating your tires, ensure the lug nuts are torqued to 140 lb-ft in a star pattern.
Proper tire pressure is usually 35 PSI for most trims, but always check the sticker on the driver’s side door jamb. Maintaining correct pressure is essential for even tire wear and optimal fuel economy.
Safety Features and Driver Assistance
The 2020 Blazer was built with a suite of safety technologies designed to protect passengers and prevent accidents before they happen. This is a key part of the 2020 chevrolet blazer specifications for family-oriented buyers.
Standard features include a high-definition rearview camera and Teen Driver technology. The latter allows parents to set speed alerts and volume limits for younger drivers, encouraging safer habits behind the wheel.
Available safety upgrades include:
- Forward Collision Alert: Warns of an impending front-end crash.
- Lane Keep Assist: Gently steers the vehicle back if it drifts.
- Adaptive Cruise Control: Maintains a set distance from the car ahead.
- Rear Cross Traffic Alert: Essential for backing out of busy parking spots.
If you experience issues with these sensors, they are often located behind the front grille or the windshield near the rearview mirror. Keep these areas clean and clear of debris to ensure the systems function correctly.
Common Problems and Troubleshooting Tips
While the 2020 Blazer is generally reliable, every vehicle has its quirks. Being aware of these can save you time and money at the dealership.
“Shift to Park” Message
A common issue reported by owners is the “Shift to Park” message appearing even when the vehicle is in park. This often prevents the car from turning off completely, draining the battery.
This is usually caused by a faulty microswitch in the shifter assembly. DIYers can often fix this by installing an inline wiring harness or replacing the shifter unit itself. If you aren’t comfortable with interior trim removal, a professional can handle this quickly.
Brake Pedal Feel
Some drivers find the brake pedal in the Blazer to be somewhat “stiff” or “wooden” compared to other SUVs. This is often due to the electro-hydraulic braking system (e-boost).
This system replaces the traditional vacuum booster. While it feels different, it provides very consistent braking performance. If the pedal feels spongy, however, you likely have air in the lines and need a proper brake bleed.
