Problem of loss of coolant

[hito1060]

Hello I have a GMC Sierra 2500 HD Duramax 6.6 V8 2002 model that is losing coolant, we have not detected any leaks, engine oil is clean, not heat.

If anyone has had similar experience and can guide us appreciate it.

Thank you very much.

My guess is it is the Intake gasket is leaking...very common

I just replaced mine a couple weeks ago. Mine was leaking to the outside without ever having any detectable coolant leak. I was lucky that it did not start to leak into the motor as it will trash on pretty quick. Looking at the gasket I was lucky to do it when I did as there wasn't much of the gasket left to keep it out of the motor.
