HOW TO DIAGNOSE A COOLANT LEAK! Pressure Test And Vacuum Bleed Test. Find a coolant leak quickly!

In this video, I have a vehicle that has an active coolant leak and it has not yet been diagnosed. I show you how to test for and diagnose a coolant leak using a coolant pressure tester and a vacuum bleeder. Coolant leak testing is being performed on a BMW E70 X5 with an N55 engine. However, this procedure will work on any vehicle. This coolant leak test applies to general automotive diagnosis steps.
