How to Bleed the Coolant When Replacing It in a Volkswagen Lavida?

The method for bleeding the coolant when replacing it in a Lavida is as follows: 1. Open the radiator cap and coolant reservoir cap, directly disconnect the hose connected to the radiator to drain the coolant, and briefly start the engine to evacuate. 2. After draining, flush the radiator and hoses with clean water while the engine is running. 3. Tighten the hoses and add new coolant. 4. After adding 2 bottles, start the engine to bleed the system, then continue adding coolant until it meets the specified level. Below is an introduction to the Lavida: 1. The Lavida is Shanghai Volkswagen's first independently developed A-segment car, with body dimensions of 4605mm in length, 1765mm in width, and 1460mm in height, and a wheelbase of 2610mm. 2. In terms of appearance, the front fascia design of the Lavida is significantly different from previous Volkswagen A-segment models, especially its unique teardrop-shaped headlight design.

I've done the coolant bleeding procedure on my Lavida several times. First, drain the old coolant completely without leaving any residue. Then pour in new coolant. The crucial step is bleeding: start the engine, set the cabin heater to maximum temperature to circulate the cooling system. After the temperature rises, locate the small bleeder valve on top of the radiator - be careful not to burn your hand - gently loosen it with a wrench until air escapes and only bubble-free liquid flows out. Finally, turn off the engine, check the coolant level after cooling, and top up if low. Incomplete bleeding can cause engine overheating, wasting fuel or damaging components, so I usually repeat the process twice to confirm. This method works well and saves a lot compared to shop service.

I was a bit nervous when I first learned to change the coolant, but later found that the bleeding process wasn't actually difficult. The procedure is: after draining the old fluid, pour in the new one, start the car and let it run for a few minutes to warm up while turning the cabin heater to maximum to accelerate circulation. Near the Lavida's radiator, you can find the bleed valve - use a special tool to slightly loosen it, releasing air bubbles until steady fluid flow appears before tightening. Wait for the system to cool before checking the fluid level and topping up. The bleeding process requires patience; work quickly when the engine is hot to avoid burns. Remember not to let air remain in the system, as it reduces cooling efficiency and may trigger engine warnings at highway speeds. Paying attention to these details makes the whole process smoother after coolant replacement.

Exhausting antifreeze simply put: After replacing with new fluid, start the engine to warm up, turn on maximum heater to circulate the water. Locate the vent hole on the Lavida's radiator, open the valve to release air until liquid flows cleanly. After cooling, check and top up. Failure to exhaust air may cause engine overheating - safety first.
