A system for a downhole tool comprising:
- a vent extending from an inner diameter of the downhole tool to an outer diameter of the downhole tool;
- a sliding sleeve configured to move to cover and uncover the vent;
- a plunger positioned on the sliding sleeve, the plunger having a first passageway for fluid, and the plunger being configured to create a second passageway for fluid, the first passageway extending through the plunger, the second passageway extending between an outer surface of the plunger and an inner sidewall of the downhole tool, the first passageway having a first inlet being exposed to a central bore of the downhole tool above the plunger, the first passageway having a first outlet being exposed to the central bore of the downhole tool below the plunger, the second passageway having a second inlet being exposed to the central bore of the downhole tool above the plunger, the second passageway having a second outlet being exposed to the central bore of the downhole tool below the plunger;
- a device configured to apply a first force against the sliding sleeve, wherein the sliding sleeve moves from a first mode to a second mode based on the first force and a second force associated with fluid flowing through the inner diameter of the downhole tool.

A system for a downhole tool comprising:
- a vent extending from an inner diameter of the downhole tool to an outer diameter of the downhole tool;
- a sliding sleeve configured to move to cover and uncover the vent;
- a plunger positioned on the sliding sleeve, the plunger having a first passageway and being configured to create a second passageway for fluid;
- a device configured to apply a first force against the sliding sleeve, wherein the sliding sleeve moves from a first mode to a second mode based on the first force and a second force associated with fluid flowing through the inner diameter of the downhole tool, wherein the second passageway is configured to be closed in a first mode when the sliding sleeve does not cover the vent, and the second passageway is configured to be open in a second mode when the sliding sleeve covers the vent.

A system for a downhole tool comprising:
- a vent extending from an inner diameter of the downhole tool to an outer diameter of the downhole tool;
- a sliding sleeve configured to move to cover and uncover the vent;
- a plunger positioned on the sliding sleeve, the plunger having a first passageway for fluid and a second passageway for fluid, the first passageway extending through the plunger, the second passageway extending between an outer surface of the plunger and an inner sidewall of the downhole tool, the first passageway having a first inlet being exposed to a central bore of the downhole tool above the plunger, the first passageway having a first outlet being exposed to the central bore of the downhole tool below the plunger, the second passageway having a second inlet being exposed to the central bore of the downhole tool above the plunger, the second passageway having a second outlet being exposed to the central bore of the downhole tool below the plunger;
- a device configured to apply a moving force against the sliding sleeve, wherein when a pressure force created by flowing fluid through the inner diameter of the downhole tool is greater than the moving force the sliding sleeve moves from a first mode to a second mode.

A method associated with a downhole tool comprising:
- forming a vent extending from an inner diameter of the downhole tool to an outer diameter of the downhole tool;
- positioning a sliding sleeve within the downhole tool, wherein the sliding sleeve is configured to move to cover and uncover the vent;
- positioning a plunger within the sliding sleeve, the plunger having a first passageway for fluid and, and the plunger being configured to create a second passageway for fluid, the first passageway extending through the plunger, the second passageway extending between an outer surface of the plunger and an inner sidewall of the downhole tool, the first passageway having a first inlet being exposed to a central bore of the downhole tool above the plunger, the first passageway having a first outlet being exposed to the central bore of the downhole tool below the plunger, the second passageway having a second inlet being exposed to the central bore of the downhole tool above the plunger, the second passageway having a second outlet being exposed to the central bore of the downhole tool below the plunger;
- applying a first force against the sliding sleeve;
- moving the sliding sleeve from a first mode to a second mode based on the first force and a second force associated with fluid flowing through the inner diameter of the downhole tool.
