2016 Chevrolet Malibu Coolant Capacity & Type

The 2016 Chevrolet Malibu holds between 6.9 and 11.1 quarts (6.5 and 10.5 liters) of coolant, depending on the engine option.

Quick Answer

• Total Cooling System Capacity: 6.9 to 11.1 quarts (6.5 to 10.5 liters)
• OEM Coolant Specification: GM DEX-COOL® (Orange, OAT, GM 6277M)
• Mix Ratio: 50/50 with deionized water (pre-mixed is recommended)

Capacity by Engine Option

The 2016 Malibu was available with three different engine options, each with a different cooling system capacity.

Flush Interval

It is critical to service your cooling system at the recommended intervals to prevent corrosion and ensure proper engine temperature regulation.

• Normal Service: 5 years or 150,000 miles (whichever comes first).
• Severe Service: If the vehicle is operated under severe conditions (e.g., frequent towing, extensive idling, dusty environments), it is wise to inspect the coolant more frequently and consider a flush sooner.

How to Refill & Bleed

Refilling and bleeding the cooling system on a 2016 Malibu is crucial to prevent air pockets, which can cause overheating.

1. Mix Coolant: If using concentrate, mix the DEX-COOL® 50/50 with deionized water in a clean container.
2. Fill System: Slowly add the coolant mixture to the coolant reservoir until it reaches the "Full Cold" line.
3. Bleed the System: This generation of Malibu does not have a traditional radiator cap; all filling is done through the pressurized coolant reservoir. There are also no specific bleeder screws accessible to the average DIYer. The preferred factory method is to use a vacuum-fill tool (like the J-43691-A) to eliminate air pockets during the fill. For those without a vacuum filler:
   • Leave the reservoir cap off.
   • Start the engine and turn the heater to its highest temperature setting with the fan on low. This ensures coolant circulates through the heater core.
   • Allow the engine to idle. As it warms up and the thermostat opens, the coolant level in the reservoir will drop. Continue to top it off, keeping it at the "Full Cold" line.
   • Let the engine run for 15-20 minutes, or until the cooling fans cycle on and off. You should see bubbles stop coming up into the reservoir.
   • Once the engine is fully warmed and no more bubbles are present, securely install the reservoir cap and check for leaks.
   • Allow the vehicle to cool completely and re-check the level, topping off as needed.

Common Cooling System Issues

The 2015-2019 generation of Chevrolet Malibu is generally reliable, but some cooling system issues are known to occur:

• Water Pump Failure: The water pump can be a failure point. Symptoms include a coolant leak from the front-center of the engine, a whining or grinding noise, or an overheating condition.
• Coolant Leaks: Leaks can develop from various places, including the radiator, heater hoses, or the coolant reservoir itself. A visual inspection for orange crusty residue or wet spots can help pinpoint the source.
• Thermostat Issues: A thermostat that is stuck open or closed can cause the engine to either take a very long time to warm up or overheat quickly. This may trigger a check engine light.
• Radiator Fan Malfunction: The electric cooling fans are critical for low-speed and stationary cooling. If a fan motor fails, the car will be prone to overheating in city traffic.

If you are experiencing any of these issues, it is best to have your vehicle inspected by a professional. Find a trusted shop on Repairius.
