    Hey all. Noticed since last oil change, my coolant level has gone from the max line down to below the minimum. After taking off the engine cover and inspecting hoses I found one if not the only hose leaking. It does appear raised as if the pressure in the line caused this to happen due to poor hose clip placement or just failure in general. Has anyone seen this? Do I need a new hose and clip or for it to just be further inserted and clamped? It's warrantied, I just want to make sure Ford will do the proper repair rather than Band-Aid it.

    Hose rad to supply tank vent---Water outlet connector

    Here's the location of leak:

    And here's the diagram of where it leads to (reservoir tank, etc.) The blue circles represent the two connections (diagram is gen 1 coyote but it appears to be the same line connection as my 2017 GT
    The car is a 2017 GT premium with 32,000km on it (20k miles?) 20190815_185038.jpg

    I think there was a TSB about a coolant leak at that location. I'm not on my main computer where I could look, buy maybe someone else can find it. Your dealer should be able to find the TSB, so be sure to ask them to look.

    If I recall correctly, the leak is coming from where the metal tube is pressed in and sealed in that small housing. The fix is to replace that small housing assembly.

    Here's the TSB I was thinking of, but after looking at it I don't think your leak is were the TSB is addressing - plus it only applies to some 2015 Mustangs and yours is a 2017. Your leak is on the metal tube that is pressed into the aluminum housing. I do recall at least one other guy on this board reporting a similar leak as yours. Your dealer should be able to see the leak and have an appropriate fix.

    Unfortunately the hose that is leaking is the other one connecting to the reservoir tank, not the one from reservoir tank to radiator. I will try and press a full hose replacement though as I don't think a simple reclamp will work
