Blue-Green fluid leaking from metal pipe - not engine coolant

[lindylead]

Hi,

I have a 2018 Outlander PHEV with a fluid leak. There are a pair of houses that run from the engine compartment toward the back of the car. They are on the underside of the car, below the driver's seat. See attached pictures. One of the pipes got loose and then bent. When I tried to bend it back, it broke and started leaking a blue-green fluid that feels like brake fluid.

Can anyone tell me what this part is and if a home mechanic can fix this? Thank you.

I think it might be this piece:

Does anyone know where I can find a repair manual for this vehicle and/or how hard this would be to replace?

Looks like the lines that go to and from the electric heater. I really didn't like that they ran them outside of the cabin and didn't insulate (or protect) them.

That is definitely it. Your post with the thermal camera is awesome.

It is de facto an engine coolant.
Once the engine warms up and the 4way valve open it connects to electric heater loop which you show damaged.

The AC heater loop works in EV mode without the engine running..... sends all that nice hot fluid outside to cool off before entering the cabin.

I made a skid plate to protect the pipes, there are uploaded pictures, but they seem corrupted.
If you cant see them, I'll see if I can find them and upload them again.

They are just asking to get damaged, they should either have not been routed here or protected with a shield.

Thank you, I would love to see the pics. Both parts of the pipe are damaged, so I ordered a new part. It looks like it won't be too hard to install. I can't imagine how much the dealer would have charged.

I'll try and find them.
I think others have repaired it by cutting out the aluminium pipe and fitting lengths of flexible rubber hose, you would need the skid plate to hold these up. I am on my second Outlander and the first job I did was to make another skid for it.
