Active Fuel Management (AFM)—also known as Cylinder Deactivation—is GM’s variable-displacement engine technology. It's designed to improve fuel economy by allowing V6 and V8 engines to deactivate cylinders under light-load conditions, such as steady highway driving. When deactivated, these cylinders are closed off and filled with trapped air, effectively turning them into air springs. This reduces energy loss through pumping, helping the engine run more efficiently while maintaining a smooth driving experience. 👨‍🔧 How AFM Works 🔧 Hydraulic Lifter Control AFM uses a combination of solenoids and hydraulically-actuated lifters, located in the engine valley, to disable specific intake and exhaust valves. These lifters, supplied by Eaton and Delphi, temporarily prevent certain cylinders from firing, allowing the engine to operate in a leaner mode when full power isn't ... read more

Too much heat presents a great challenge to motor vehicles. Thankfully, all vehicles have a measure to keep themselves cool. The car's engine has a cooling system aided by a coolant, a fluid that runs in the engine and transmits heat away from it. The coolant should remain clean for it to function effectively. Dirty coolant must be flushed out and replaced with a fresh one. But how do you know when your coolant needs flushing? To know this, be on the lookout for the following symptoms. Your Vehicle Overheats As stated above, the role of the coolant is to keep your engine temperatures low.
