What You'll Learn
The fuel tank is made of plastic and cannot be repaired
The fuel tank in a 2007 Chevrolet Cobalt is located underneath the vehicle, towards the rear. It is a plastic tank that contains the electric fuel pump and fuel gauge sender. While metal tanks are stamped and welded, plastic tanks are created through blow molding.
Although plastic fuel tanks are durable, they are susceptible to leaks and damage over time. Unfortunately, there are no reliable repair procedures for plastic fuel tanks. While some resources suggest using a plastic tank repair kit, reviews are mixed. Some customers report that the repair kit works well on plastic gas tanks, particularly Stihl tanks, and is a cost-effective alternative to replacing the tank. However, others have found that the repair kit does not adhere to the tank surface and fails to seal leaks effectively.
Due to the unpredictable nature of these repair kits, the only approved service for a damaged plastic fuel tank is a complete replacement. When replacing the fuel tank, it is recommended to do so when it is nearly empty. If that is not possible, the remaining fuel should be siphoned out before removing the tank. This process involves several steps, including relieving the fuel system pressure, disconnecting the cable from the negative battery terminal, raising the vehicle, and detaching various components, such as hoses, cables, and the fuel pump.
It is important to note that attempting to repair a plastic fuel tank without proper expertise and approved procedures can be dangerous and may void any manufacturer's warranty associated with the vehicle. Therefore, it is always advisable to consult a certified mechanic or a Chevrolet specialist for guidance and assistance in handling fuel tank issues.

The low fuel light comes on when there is less than 15% of fuel left
The 2007 Chevrolet Cobalt has a fuel tank capacity of 13 gallons. The fuel tank is located underneath the vehicle and can be accessed by first relieving the fuel system pressure and disconnecting the cable from the negative battery terminal. The vehicle should then be raised and secured on jack stands. The fuel tank is made of plastic and contains the electric fuel pump and fuel gauge sender. It also has baffles to check fuel thrashing and is part of the Evaporative Emission Control System.
In some cases, the low fuel light may come on earlier than expected, or the fuel gauge may not be accurate. This could be due to various factors such as a faulty fuel pump, clogged fuel filter, or issues with the fuel level sensor. If the low fuel light illuminates frequently or the gauge is inconsistent, it is advisable to have the vehicle inspected by a professional mechanic to diagnose and address any underlying issues.
To avoid fuel gauge issues and ensure accurate readings, it is important to maintain the fuel system, including regular fuel filter replacements and ensuring proper sealing of the fuel cap. Additionally, issues with other sensors, such as the mass airflow sensor or oxygen (O2) sensor, can also impact fuel efficiency and, consequently, the accuracy of the fuel gauge.
When the low fuel light comes on, it is essential to refuel as soon as possible. Running a vehicle with very low fuel levels can cause potential issues, such as fuel pump damage or fuel line problems due to debris in the fuel. It is also important to note that the fuel tank of the 2007 Chevrolet Cobalt should be refilled when it is nearly empty or, if necessary, the remaining fuel should be siphoned out before removing the tank for any maintenance or repair work.

The fuel tank is prone to developing corrosion
The 2007 Chevrolet Cobalt has had several complaints regarding its fuel tank. The fuel tank is prone to developing corrosion, which can lead to fuel leaks. This issue is not limited to the 2007 model, as there have been similar complaints about the 2005 and 2006 models. In some cases, the fuel tank was found to be cracked, potentially due to a manufacturer defect. This defect can cause fuel leaks and even fires, posing a serious safety hazard.
The fuel tank in the 2007 Chevrolet Cobalt is made of plastic and, as a result, cannot be repaired. The only approved solution to a damaged fuel tank is a replacement. This process can be costly, with some customers reporting expenses of up to $1000.
To remove the fuel tank, it is recommended to start with an almost empty tank. If that is not feasible, siphoning out the fuel is advised. The next steps involve relieving the fuel system pressure and disconnecting the cable from the negative battery terminal. After raising the vehicle and securing it on jack stands, the remaining fuel should be siphoned out or hand-pumped. The exhaust pipe, muffler insulators, and heat shield are then removed.
Disconnecting the electrical connectors for the fuel pump/Fuel Level Sensor module and the EVAP canister vent solenoid hose is crucial. Marking and disconnecting the EVAP system hoses, fuel filler neck hose, and fuel tank ground strap are subsequent steps. Finally, detaching the fuel filter connectors and separating the lines leading to the tank allows for the complete removal of the fuel tank.
Due to the safety hazards associated with a faulty fuel tank, it is imperative to address any signs of corrosion or leaks promptly. While there have been investigations and complaints, it is unclear if Chevrolet has issued a recall for this specific issue.

Fuel tank replacement is the only approved service for leaks or damage
The fuel tank in a 2007 Chevrolet Cobalt is located underneath the vehicle, towards the rear. It is a plastic tank that contains the electric fuel pump and fuel gauge sender. While metal tanks can be repaired, plastic tanks cannot be repaired and must be replaced if they are damaged or leaking.
The manufacturer's approved method is to replace the entire fuel tank. This is due to the safety risks associated with fuel leaks. A leaking fuel tank can cause a strong gas smell, which is an obvious safety issue. In some cases, it may even be grounds for a recall.
To replace the fuel tank, it is recommended to start with an empty tank. If that is not possible, siphon out as much fuel as possible before removing the tank. The next steps involve relieving the fuel system pressure and disconnecting the cable from the negative battery terminal. Then, raise the vehicle and secure it on jack stands. There are many hoses, cables, and connectors to detach, including the fuel inlet line, the EVAP system hoses, the fuel filler neck hose, and the fuel tank ground strap. Finally, lower the tank completely, angling it to clear the frame and exhaust pipe, and then remove it.
It is important to note that fuel tank replacement should only be performed by qualified professionals, as it involves working with flammable liquids and hazardous materials.
