How to Replace the Antifreeze in a Bora?
2 Answers
The tutorial for replacing the antifreeze in a Bora is as follows: 1. Drain the coolant: First, open the reservoir cap (ensure the radiator cap is tightly sealed), then unscrew the drain switches on the cylinder block and radiator. This should be done while the engine is running at low speed and is warm. 2. Add new coolant. Precautions for replacing the antifreeze are as follows: 1. After the coolant is completely drained, tighten the drain switches on the cylinder block and radiator. 2. Close the radiator cap, let the engine run until it reaches normal operating temperature, then turn it off and wait until it cools to room temperature. 3. Observe the liquid level in the reservoir and add coolant as needed until no air bubbles appear in the reservoir when the engine is idling. 4. Fill the radiator with the specified coolant through the filler port until the liquid level in the reservoir reaches the designated "MAX" mark.
I changed the coolant in my Bora last year, and it wasn't that difficult to do it myself. You have to wait until the car is completely cooled down—at least two hours after parking, as opening the cap on a hot engine is too dangerous. The tools you'll need are just a wrench and new coolant; I used the original red type. Open the engine compartment, locate the white expansion tank, and unscrew the cap to release pressure. Then crawl under the car to find the radiator drain plug, usually with a blue plastic head, and loosen it with the wrench—the old coolant will gush out. Remember to place a container underneath to catch the waste fluid and avoid environmental contamination. Once it's fully drained, screw the plug back in, then slowly pour the new coolant into the tank until it reaches the upper limit. Finally, start the car and turn on the heater to circulate the fluid, topping it up to the standard level. The whole process takes about half an hour. If it's your first time, wear gloves for protection—you'll save over 200 yuan in labor costs.
