ABSTRACT:
An oil filter wrench having adjustable serrated jaws that incorporate a hollow piercing jaw tooth that is connected to a drain hose via an internal oil channel through the oil filter wrench handle and jaw portion. The piercing jaw tooth includes an "O"-ring seal which seals when the piercing jaw punctures the oil filter housing. The drain hose includes a valve and a nipple that is attachable to a squeeze type drain bulb that can be used to provide a suction for sucking the oil filter during use. Use of the oil filter wrench allows the mechanic to drain the oil filter prior to removing the oil filter from its mount thereby preventing oil from draining onto the mechanic's hands and onto the vehicle parts.
