How to Drain the Radiator of Wuling Sunshine?
3 Answers
The Wuling Sunshine radiator has a dedicated drain screw located at the bottom right corner of the radiator. The screw is made of plastic and is relatively fragile. The method to drain the radiator water is very simple: just unscrew the drain screw. After draining, be especially careful not to overtighten the screw when screwing it back in, as it can easily break. Relevant information about the car radiator is as follows: Introduction: A car radiator generally refers to the heat exchanger (automobile radiator). The radiator is part of the car's cooling system. The radiator in the engine's water cooling system consists of three parts: the inlet chamber, the outlet chamber, the main plate, and the radiator core. Malfunctions: The hoses of the engine radiator can age and become prone to cracking after long-term use, allowing water to easily enter the radiator. If a hose ruptures while driving, the high-temperature water spraying out can form large clouds of steam escaping from under the engine hood. When this happens, immediately choose a safe place to stop the vehicle and take emergency measures to address the issue.
When I drove the Wuling Sunshine before, I changed the coolant myself. First, park the car on level ground and turn off the engine, waiting until it cools down completely to avoid getting scalded by hot water. Crawl under the car to locate the radiator, which usually has a plastic drain plug at the bottom—use a wrench to turn it counterclockwise. Remember to place a large basin underneath to catch the old coolant, as it's toxic and shouldn't be disposed of carelessly. After draining, screw the plug back in, then refill with new antifreeze from the expansion tank in the engine bay. The key is to bleed the air—top it up, start the engine, and let it idle for a few minutes. The coolant level will drop, so keep topping it up until it stabilizes. Doing this yourself can save around a hundred bucks in labor costs, but beginners should ideally get an experienced driver to assist.
I once drained the coolant from my Wuling Zhiguang myself. The key is to prepare gloves and goggles. With the engine cold, crawl under the car and locate the drain valve along the radiator hose - there's a plastic plug with a cross-shaped groove at the bottom right side. Loosen it slowly with pliers, as sudden opening may cause coolant splashing. I noticed lots of rust sediment during draining, so I flushed the radiator with clean water. When refilling, make sure to use OEM-spec antifreeze of the same color (about 4 liters needed). After refill, let the engine idle for 10 minutes with the cabin heater on to help circulate and purge air. Finally, check all hose connections for leaks. The whole process took an hour - more troublesome than expected but quite rewarding.
