What size is the drain plug for the Volkswagen Lavida?
2 Answers
Lavida engine drain plug is 18mm. Replacement conditions: The drain plug is made of steel and of good quality. Under normal usage frequency, it is difficult to strip unless the threads are misaligned and excessive force is applied. Therefore, the drain plug does not need to be replaced. However, some cars use a plastic oil pan, in which case the drain plug is a one-time use item and needs to be replaced each time. Washer: The washer serves as a seal. Since engine oil is a fluid with strong permeability, the contact surface between the drain plug and the oil pan cannot be perfectly flat. If the two are in direct contact, the surface will not fit tightly enough, leading to oil leakage.
Hey, I've been tinkering with changing the oil on my own car recently. On the Volkswagen Lavida, I've always used a 14mm drain plug, to be more specific, with an M14×1.5 thread size. Last time during maintenance, I used a 17mm hex wrench to remove it—tightening it just right is crucial; too tight and you risk stripping the oil pan threads, too loose and you'll have oil leaks. Don't underestimate this little bolt; when replacing it, oil tends to spill and mess up the garage, so I placed a new copper washer to fix that. It's best to check the vehicle manual for confirmation, as sizes might slightly vary by year—post-2015 models generally maintain this spec. During routine maintenance, don't forget to check for rust on it, and consider replacing the drain plug with each oil change to avoid future hassles.
