A special male quick-connect fitting will be needed to replace the
coolant drain petcock. Vehicles not built with this fitting are easily
retrofitted. Refer to TMC RP353 or ISO 16028 to ensure that you have
the proper fitting. Please ensure that this fitting is installed on the
vehicle before using the tool. If the truck is not equipped with the
fitting, connect the Vacuum Module to the surge tank, follow steps
1- 4 under the Vacuum Procedure to draw partial vacuum and swap
the cooling system drain-cock with the Male Quick Connect Fitting.
2.
Inspect the coolant level of the storage tank and engine.

If there is a known leak in the system a Gravity Drain must be per-
formed using Drain Procedure Steps 1 and 2. After necessary repairs
have been made, proceed to the Pressure Test Procedure on page 5.
4.
Check the screen in the Y-Strainer on the Tank Valve for debris.
