How to Replace the Antifreeze in a Magotan?
3 Answers
Magotan antifreeze replacement method is as follows: 1. Unscrew the radiator drain valve, usually located at the bottom of the car, to drain the old antifreeze; 2. Flush the cooling system by continuously adding clean water into the engine cooling system. During the flushing process, keep the engine idling to ensure the circulation of clean water inside until clear water flows out from the radiator; 3. Wait for the water to drain completely, then close the drain valve and add new antifreeze until the liquid level is between the max and min marks; 4. Close the cap, start the car, and let the engine idle for two to three minutes. The cooling system will expel internal air, causing the antifreeze level to drop slightly. Top up the antifreeze again; 5. Ensure the liquid level remains between the max and min marks, tighten the radiator cap, and complete the antifreeze replacement. The Magotan's body dimensions are 4866mm in length, 1832mm in width, and 1464mm in height, with a wheelbase of 2871mm.
I've changed the coolant in my Magotan several times before. Remember to wait until the engine is completely cooled down before starting. Prepare a bucket to catch the waste fluid, first unscrew the drain plug (usually located at the bottom of the radiator). After the old fluid has completely drained, it's best to flush the system twice with distilled water. Here's the crucial part—Volkswagen vehicles must use pink coolant that meets the G12 standard. Last time I mixed it with another brand, and it ended up corroding the radiator. When refilling, turn the heater to maximum, and while adding the coolant, squeeze the hoses to release air bubbles. The system is properly circulating only when the electric fan kicks in. Finally, make sure the coolant level in the expansion tank stays between the max and min marks. This whole process takes about half an hour to do alone.
Last month, I just helped my dad replace the coolant in his Magotan, and I noticed a few key points: The engine underguard must be removed to access the drain valve, and special pliers are needed for the hose connector clips to avoid damaging the parts. Before refilling, always check the hoses for signs of aging or leaks. From my experience, replacing the thermostat at the same time as the coolant saves a lot of hassle. Pay special attention to ensuring the vent hole near the expansion tank is clear—once, I forgot to clean it, which caused abnormal temperature rises. The coolant-to-distilled water ratio must be strictly 1:1, and it's best to verify with a refractometer for peace of mind.
