How to Bleed Air from the Emgrand EC7 Radiator?
2 Answers
Emgrand EC7 radiator air bleeding method is as follows: 1. Open the radiator cap and fill it with water; 2. Start the vehicle, turn on the heater, and let the engine idle. Add water if the radiator level drops; 3. Once the engine coolant undergoes a major circulation and the electric fan starts running, close the radiator cap. The car radiator, also known as a heat exchanger, is a key component in the vehicle's cooling system. Its function is to dissipate heat. The coolant absorbs heat in the water jacket, flows to the radiator to release heat, and then returns to the water jacket for circulation, achieving temperature regulation. The Emgrand EC7 is a globally quality sedan developed by Geely Group and the first model under the Emgrand brand. The vehicle features four-wheel disc brakes, front-wheel drive, a trunk capacity of 680 liters, and a fuel tank capacity of 50 liters.
I've handled the air bleeding procedure for the Geely Emgrand EC7's cooling system multiple times. First, ensure the engine is completely cool - ideally left overnight - safety comes first. Open the hood and locate the expansion tank, then gently unscrew its cap. Start the engine and let it idle while you carefully observe the coolant flow. You'll notice bubbles gurgling out from the tank opening, indicating air is being purged. Wait patiently for about ten minutes until the coolant temperature reaches around 90°C and the radiator fan kicks in - by then most bubbles should disappear. Remember to top up with OEM coolant between the MAX and MIN marks as the level drops, but never fill it completely. Keep a close eye on the temperature gauge throughout the process - shut off the engine immediately if anything seems abnormal. Before final tightening, check all hoses for potential leaks. For best results, take a short test drive afterward and recheck the coolant level. Air pockets in the cooling system can easily cause engine overheating, so never take this procedure lightly.
