Here, you will have the opportunity to communicate your concerns, issues, and possible solutions pertaining to current and proposed regulations. 2013 Chevy Volt in Reduced Propulsion Power state with P1E00 and P0AFA codes. Only the SAE 2023 Thermal Management Systems Symposium (TMSS) provides you critical access directly to the industry’s leading experts who are ready to share their latest innovations and solutions.Īt TMSS you will engage with engineers from OEMs, Tier 1 & 2 suppliers, regulatory entities, and other discrete part developers from around the globe to discuss industry trends, the latest thermal management and climate control strategies, developments, and systems integration, and still to-be-developed technology impacting thermal systems management. Your coolant level sensor has detected that the coolant is low and it has. The ongoing goal is to reduce engine emissions, conserve energy, dissipate heat, reduce noise, improve the cabin environment, and increase the overall vehicle performance. Read more about the Volt’s power electronics coolant loop.ĭuring this time of technical transition and transformation to advanced propulsion, it is more important than ever to have access to timely, relevant information and updates in the areas of cutting-edge technology, standards, regulations, and testing to inform and align strategic initiatives. The power electronics cooling system also uses an air separator device to prevent air-bubbles from affecting cooling performance and utilizes a surge tank that acts as a coolant reservoir, and facilitates the routine addition of coolant via a pressure cap. The power electronics cooling system radiator is the upper half section of a dual radiator assembly that is common with the high voltage battery cooling system. The Chevrolet Volt uses a high flow 12-volt electric pump to create and control the coolant flow which passes through - in order - the plug-in battery charger assembly, the radiator, the power inverter module (PIM), and then back to the pump. It is essential that the heat developed by the power inverter module and the plug-in battery charger while operating the Volt or when plugged in be dissipated in order to prevent damage to the components. A good routine flush of your antifreeze coolant system helps us avoid this problem.A GM article explaining the Chevrolet Volt’s cooling/heating systems notes that the power electronics coolant loop is designed to insure the main underhood electronics do not overheat during use. Eventually, the un-flushed coolant/debris mixture, in your radiator, turns into a brown sludge that can clog vital parts in your radiator hose and other parts of your engine, leading to engine overheating. Deteriorated coolant becomes acidic and eats away at metal cooling system components in your radiator and other parts of the engine. If you’ve got antifreeze gunk build-up in your radiator or radiator hose, your car is long overdue for a coolant flush. That’s why you should have your coolant flushed per the recommended service schedule. But you don’t want to let it get to that point. In some cases, if the coolant goes long enough without service, it will start to darken and become brownish in color. Make sure to flush your antifreeze coolant at the time and mileage recommended by the automaker. Don’t wait until your coolant is discolored and funky looking.
