Hello friends, I have been using this site since i purchased my 2015 EcoDiesel about a year ago and thought I would share my coolant issue I had with some pictures and videos to help the next fellow.
I have been experiencing the mystery coolant leak like several folks have noted here where the pressure tank would drop coolant levels randomly, however did not have any visual leaks. That was up until about a month ago, I walk out to my truck and see a puddle underneath the rear part of the engine.
I inspected the front hoses, took off the belt cover to expose the water pump and it was mostly dry, no evidence of leaks. After putting it on jack stands it started running down the bottom of the oil pan and transmission pan cover. After researching some more posts on this site, I narrowed it down to the dreaded turbo coolant line as a possibility.
A quick call to the local dealer and he verified it was not covered on the EGR extended warranty, and I already knew the labor cost would be 2-3K so I dove in with the help of the "too much soot" video on youtube. So I ordered a new turbo coolant hose off amazon with the braded flexible part of the line, the 5mm ball end Allen wrench, and also as a backup a 3/8 silicon hose with clamps. After working about 5-6 hours leaning over the truck (multiple days) I finally got the intake manifold out and with relief saw a puddle under the coolant rubber portion of the line and a slow drip. Not happy that it happened, just happy did not spend all this time and body ache for that not to be the problem.
This is were I am stopping for the day and have decided to give a go at replacing the entire line as opposed to just the rubber portion. There is another solid line in the way of the upper turbo coolant banjo nut that I am going to try and take off, but need a flexible end ratcheting 19mm wrench to take off one of the line connectors.
Also the intake manifold was pretty clogged up so I am going to attempt to clean. Acouple rounds of degreaser and the water hose got alot of it, but I am going to try some oven cleaner after I get some.
I'll update the post as I go.
