Re: 3.0 coolant leak, please help identify the leaking part (pictures and ETKA included)
The way I see it, the elbow near #14 is ABOVE the #55 part. On the connector pipe from the right head to the left head looking at the left elbow, that is ware there is the most coolant residue flowing around the pipe at the left elbow where the straight left to right pipe attaches to the elbow. From the parts diagram, the view show a small hose connection that goes to the expansion tank that's #21 and #36. So, the coolant bleed hose to the expansion tank, #21 with #36 must be leaking at the connection to the coolant crossover pipe, or in the hose coupling #21 where #36 is attached with a hose clamp.
