The fuel pump in a 2015 Chevy Malibu is mounted inside the fuel tank (an in-tank pump) with access via a panel beneath the rear-seat cushion in the cabin. It is not located in the engine bay. This article explains where to find it, how access works for maintenance, and what to expect during service.
Location and design
In-tank configuration
For the 2015 Malibu, the fuel pump is part of the fuel pump module located inside the fuel tank. The module includes the pump, fuel sending unit, and associated connections. The design keeps the pump submerged in fuel, which helps with cooling and reduces noise. There is no conventional in-engine bay fuel pump in this model line.
Access and maintenance
Steps to access the pump
Access to the fuel pump is typically provided by an access panel located under the rear-seat bottom cushion in the passenger compartment. The general process is as follows:
- Park safely, apply the parking brake, and disconnect the negative battery cable to prevent sparks.
- Fold up or remove the rear-seat cushion to reveal the fuel pump access panel on the top of the fuel tank area.
- Remove the access cover, unplug the electrical connector, and carefully detach the fuel lines from the pump module, noting orientation for reassembly.
- Lift out the pump module from the tank (or loosen the lock ring, depending on the exact design) and replace with a new unit if needed.
- Reinstall in reverse order, ensuring a proper seal and reconnected wiring, then check for leaks after reassembly.
Access methods can vary slightly by production run or trim, but the general approach for a 2015 Malibu is to use the rear-seat access rather than dropping the tank from underneath. If the access panel is damaged or missing, consult a repair manual or dealership service to avoid fuel-system hazards.
Safety and practical notes
What to consider before attempting maintenance
Fuel systems are hazardous. Always follow the vehicle’s service manual, depressurize the system, work in a well-ventilated area, and wear eye protection. If you’re uncertain about the procedure, seek professional service to avoid leaks or fire risks.
What varies by model year or trim
Consistency across the Malibu lineup
Across the 2013–2015 Malibu range, the in-tank fuel pump design and rear-seat access approach are generally consistent. Some trims or production changes may alter the exact access panel design or mounting hardware, but the fundamental location inside the tank and access from the rear-seat area remains standard for this generation.
Summary
In short, the 2015 Chevy Malibu’s fuel pump is located inside the fuel tank as an in-tank unit, with access through a panel under the rear-seat cushion in the cabin. Maintenance typically involves removing the access cover, disconnecting wiring and lines, and lifting the module out of the tank. Always follow safety guidelines and consult the service manual or a professional if you’re unsure about the procedure.
