I am attempting to drain my 6L for the first time, and encountering surprises or possible issues, or I don't know this motor like I thought. I am following this diagram;
I disconnected the inlet hose to the transmission cooler (1 in diagram) and the raw water pump outbound hose (#2 in diagram), water comes out fine.
For #3, Fresh Water Drain, is located in the middle of the heat exchanger, and will drain coolant. The Raw Water Drain is located on the passenger side, more towards the top at like 2 o'clock. Here is an image;
When removing the Raw Water Drain, nothing comes out as it is facing upward, should I remove the hose coming from below?
When removing the the Exhaust manifold hose (#4) and the Exhaust corner drain plugs (#5), radiator fluid, or at least a mixture of predominantly coolant comes out.
Therefore, in following the instruction manual, as well as guidance from others, there seems to be something going on for coolant to be coming out.
Here is a link to the manual I am using;https://pcmengines.com/wp-content/uploads/2017/09/imagesOwners-Operations-Manual-2011.pdf@Jody_Seal
hopefully you may have some insights.
Thank you for any help and recommendations.
