Procedure notes
Follow the steps in this video to see how to fix minor coolant (antifreeze) leaks in your 2016 Chevrolet Express 3500. Leaking coolant / antifreeze is one of the more common types of leaking fluid from Express 3500 engines. Engine coolant (which is also called antifreeze or anti-freeze) moves through the inside of your Express 3500 engine and keeps it from overheating. Coolant / antifreeze can leak from the reservoir, radiator or any hose, in 2016 Express 3500 with the 6.6 liter engine. However, a coolant leak (aka an antifreeze leak) is most likely to occur where the hoses connect to the engine or radiator. Otherwise, your Express 3500 may have a radiator leak. This video shows you where the coolant reservoir, hoses and connections on your 2016 Express 3500 Base are located and the steps needed to fix minor leaks.
