Understanding Your 2017 chevrolet malibu gas tank size by Trim
Chevrolet designed the ninth-generation Malibu with efficiency in mind, but they did not use a “one size fits all” approach for the fuel reservoir. Depending on whether you have the base L trim, the mid-level LS/LT, the high-performance Premier, or the Hybrid, your capacity will change. This is often a point of confusion for owners who notice different range estimates in their owner’s manuals.
The 2017 Chevrolet Malibu Fuel Tank Capacity for the base “L” trim and the Hybrid model is 13.0 gallons. This smaller tank helps reduce the overall weight of the vehicle, which is a key factor in achieving higher fuel economy ratings in city driving. For the Hybrid, the space saved by the smaller tank is often utilized for the battery cooling systems and high-voltage components.
If you own the LS, LT, or the 2.0L Turbo Premier trim, your tank is larger, holding 15.8 gallons. This extra 2.8 gallons provides a significant boost to your highway range, allowing for fewer stops on long-distance hauls. Knowing which version you have is the first step in mastering your vehicle’s maintenance and performance.
2017 Malibu Fuel Capacity Quick Reference Table
| Trim Level | Engine Type | Tank Size (Gallons) |
|---|---|---|
| L (Base) | 1.5L Turbo | 13.0 Gallons |
| LS / LT | 1.5L Turbo | 15.8 Gallons |
| Premier | 2.0L Turbo | 15.8 Gallons |
| Hybrid | 1.8L Hybrid | 13.0 Gallons |
The Role of the 2017 Chevrolet Malibu Fuel Pump Module
Inside that gas tank sits the 2017 Chevrolet Malibu Fuel Pump Module, which is the heart of your fuel delivery system. This assembly does more than just push gas to the engine; it houses the fuel filter, the pressure regulator, and the fuel level sending unit. If your gas gauge is acting erratic or showing “Empty” immediately after a fill-up, the sending unit is usually the culprit.
Accessing this module typically requires a 2017 Chevrolet Malibu Fuel Tank Removal, as there is no convenient access panel under the rear seat in this generation. This makes maintenance a bit more involved for the average DIYer. If you hear a high-pitched whining sound from the rear of the car while it’s idling, your fuel pump may be nearing the end of its lifespan.
To keep this module healthy, avoid running your tank down to “E” regularly. The gasoline in the tank actually acts as a coolant for the pump motor. When the fuel level is consistently low, the pump runs hotter, which can lead to premature failure of the internal bearings and electrical windings.
Dealing with the 2017 Chevrolet Malibu EVAP System Canister
The 2017 Chevrolet Malibu EVAP System Canister is a critical component for both the environment and your car’s performance. Its job is to trap gasoline vapors before they escape into the atmosphere, storing them until the engine can safely burn them off. If you have trouble clicking the gas pump handle because it keeps shutting off, your EVAP system might be restricted.
A common issue Malibu owners face is the P0442 EVAP System Small Leak code. This diagnostic trouble code (DTC) often points to a loose gas cap, but on the 2017 model, it can also be a sign of a hairline crack in the fuel tank vent valve or a failing O-ring. Always check the easiest fix—the cap—before diving into more expensive repairs.
If the canister becomes saturated with liquid fuel—usually from “topping off” the tank after the pump clicks—it can cause the engine to stumble or stall right after refueling. To protect your EVAP system, always stop fueling at the first click. This preserves the necessary “headspace” in the tank for vapors to expand and move toward the charcoal canister.
Critical Sensors: 2017 Chevrolet Malibu Fuel Tank Pressure Sensor
The 2017 Chevrolet Malibu Fuel Tank Pressure Sensor monitors the pressure inside the tank to ensure the EVAP system is sealed and functioning. This sensor sends data to the Engine Control Module (ECM), which uses the information to run “leak tests” while you drive. If this sensor fails, you will likely see a Check Engine Light and may experience a slight drop in fuel efficiency.
Because this sensor is often mounted on top of the tank or integrated into the fuel line, it is exposed to road salt and debris. Over time, the electrical connector can corrode, leading to false readings. If you’re performing a 2017 Chevrolet Malibu Fuel Tank Removal for any reason, it is wise to inspect this sensor and its wiring harness for any signs of wear.
For those interested in the broader reliability of this model, checking a midsize reliability review can provide context on how these electronic components hold up over 100,000 miles. Most owners find that while the sensors are sensitive, they are relatively durable if the vehicle is kept clean and maintained.
Inspecting 2017 Chevrolet Malibu Fuel Tank Straps and Hardware
Safety is paramount when dealing with fuel, and the 2017 Chevrolet Malibu Fuel Tank Straps are what keep that 13 to 15-gallon payload securely attached to your chassis. If you live in the “Salt Belt,” these metal straps are prone to heavy corrosion. A snapped strap can cause the tank to sag, putting immense stress on the 2017 Chevrolet Malibu Fuel Filler Neck Assembly and fuel lines.
During your oil changes, take a moment to slide under the rear of the car with a flashlight. Look for deep pitting or flaking rust on the straps. If they look thin or heavily oxidized, replace them immediately. It is a relatively inexpensive DIY job that prevents a catastrophic failure on the highway.
The filler neck assembly is another area to watch. If you smell raw gasoline near the rear wheel well after a fill-up, the neck may have developed a pinhole leak due to corrosion. Replacing the filler neck usually involves removing the rear wheel and inner fender liner, making it an accessible project for a weekend mechanic with basic hand tools.
Maximizing Your Range and Efficiency
Now that you know the 2017 chevrolet malibu gas tank size, you can better manage your real-world gas mileage. With the 15.8-gallon tank and the 1.5L engine, many drivers report achieving over 500 miles on a single tank during highway trips. However, your driving habits play a massive role in reaching these numbers.
To get the most out of your tank, keep your tires properly inflated and ensure your air filter is clean. A restricted air filter forces the turbocharger to work harder, which can negatively impact your air-fuel ratio. Also, consider the weight you’re carrying; an extra 100 pounds in the trunk can slightly decrease your MPG over long distances.
If you ever experience electrical gremlins affecting your fuel gauge or pump, consult a fuse box diagram to check the fuel pump relay first. Sometimes a “dead” pump is actually just a blown 15-amp fuse, saving you hours of labor and hundreds of dollars in unnecessary parts.
Fuel System Troubleshooting Matrix
| Symptom | Potential Cause | Recommended Action |
|---|---|---|
| Gas gauge stays on full or empty | Fuel Level Sending Unit failure | Test resistance at the pump connector; replace module if out of spec. |
| Strong gas smell after fill-up | Corroded Fuel Filler Neck | Inspect neck and hose clamps for leaks or rust perforations. |
| Hard starting after refueling | Stuck Purge Valve / EVAP issue | Check the EVAP purge solenoid under the hood for proper vacuum. |
| Check Engine Light (P0442) | Small EVAP Leak | Inspect gas cap seal and 2017 Chevrolet Malibu Fuel Tank Vent Valve. |
| Hesitation under acceleration | Weak Fuel Pump | Perform a fuel pressure test at the rail to check pump output. |
Maintenance Tips for Long-Term Reliability
To ensure your 2017 Malibu remains a reliable companion, treat the fuel system with care. Using high-quality Top Tier detergent gasoline can help prevent carbon buildup on the direct-injection nozzles. Since the Malibu uses a high-pressure fuel system, keeping the injectors clean is vital for maintaining that smooth idle and crisp throttle response.
If you plan on storing your Malibu for the winter or an extended period, add a fuel stabilizer to the tank and run the engine for ten minutes to ensure the treated fuel reaches the injectors. This prevents the gasoline from oxidizing and turning into a “varnish” that can clog the 2017 Chevrolet Malibu Fuel Pump Module.
Lastly, always be mindful of the 2017 Chevrolet Malibu Fuel Tank Vent Valve. This small part allows air to enter the tank as fuel is consumed. If it becomes clogged with dust or spider webs (a common issue in certain climates), it can create a vacuum in the tank that actually collapses the plastic walls or starves the engine of fuel. Periodic inspection of the vent lines can prevent these strange and costly issues.
Frequently Asked Questions About 2017 chevrolet malibu gas tank size
How far can I drive when the low fuel light comes on?
In most 2017 Malibu models, the low fuel warning triggers when there is approximately 1.5 to 2.0 gallons remaining in the tank. Depending on your engine and driving conditions, this gives you a “buffer” of about 40 to 60 miles. However, you should never rely on this buffer, as running low can overheat the fuel pump.
Can I upgrade my 13-gallon tank to a 15.8-gallon tank?
While physically possible, it is not a “bolt-on” swap. The different tank sizes often correspond to different evaporative emissions setups and software calibrations in the ECM. Attempting this swap could lead to constant Check Engine Lights and issues with the fuel gauge accuracy.
What is the best way to clean the fuel system?
The most effective way is to use a high-quality fuel system cleaner containing PEA (polyetheramine) every 5,000 miles. This helps clean the 2017 Chevrolet Malibu Fuel Level Sending Unit contacts and the fuel injectors without requiring any disassembly.
Why does my Malibu take a long time to fill up?
If the pump handle constantly clicks off, there is likely a restriction in the 2017 Chevrolet Malibu Fuel Filler Neck Assembly or a saturated 2017 Chevrolet Malibu EVAP System Canister. The air in the tank cannot escape fast enough to make room for the incoming fuel, triggering the pump’s safety shut-off.
