Cannot find where coolant is coming from underneath engine in front center. Not coming from the radiator or hoses. How do I pressure test the system?

Hello,

Many times the leaks are from a bypass hose or even the thermostat housing.

Refer to this video of how to pressure test the system:

Let me know if you have any questions.

Thank you.
