öljytulpan

Öljytulpan is a Finnish term that translates to "oil plug" or "oil drain plug" in English. It refers to the specific plug that is used to seal the oil pan in an internal combustion engine. The oil pan is a reservoir located at the bottom of the engine that stores the lubricating oil. The oil drain plug is a crucial component as it allows for the draining of old engine oil during routine maintenance, such as an oil change.

When performing an oil change, the oil drain plug is typically loosened and removed, allowing the used oil to flow out of the oil pan. After the old oil has completely drained, the plug is cleaned and reinstalled, often with a new washer or gasket to ensure a proper seal. Tightening the oil drain plug to the correct torque specification is important to prevent leaks and avoid damaging the oil pan or the plug itself. The design and size of oil drain plugs can vary depending on the make and model of the vehicle. They are usually made of metal, such as steel or aluminum, and are designed to withstand the pressure and temperature of the engine's oil system.
