i am working on a 6.6 duramax in a chevy bus it has a coolant leak on the rear driverside of the motor over the oil filter i cant see where its coming from it dosent look like the head gasket is there a freeze plug there or a coolant crossover back there thanks

anybody any ideas

I had that happen on our 08 when it was new. Not sure what they did some thing they took apart right there. I will try to find out.

The water to oil intercooler is there. Maybe a gasket on it???

thanks that is exactly what it was leaking out of the top gasket
