A sump plug collects excess oil from around the engine. They are found at the bottom of the sump pan and are responsible for allowing excess oil to be drained from the engine. Sump plugs are easily damaged due to their exposed position on the car, so commonly need to be replaced. In order to prevent oil loss or engine damage, drivers often choose to replace their sump plug each time they complete an oil change. Symptoms you may have a damaged or faulty plug include excessive oil consumption, oil puddles beneath the car and an overheating engine. Replacing a plug is straight-forward and inexpensive.
