Can’t find coolant leak location...

[Muddy Bean]

Can someone familiar with the Ecoboost help a guy out? Truck is puking coolant into the ground and I can’t find where it’s coming from. I’ve had the truck on a lift checking with another guy and neither of us could find it. Both turbo coolant lines are dry. Water pump appears to be dry. No coolant hoses appear to be wet. I can’t for the life of me find this. I removed the skid plates and the only place it appears to be coming from is the power steering area where the large power steering box is. Is that thing cooled by coolant by any chance?

I've stated this numerous times, but here we go again. The only way to find small or intermittent leaks is to pressurize system. I use a Stant pressure tester with adapter, and pressurize to about 12-15 pounds. Any leaks will start spraying out. Let us know what you find.

As suggested by moose, did you check for the leak when the system was at temp (pressurized)?

Heater hoses?

Those were a popular source of leaks on the V8's

Yes. Still can’t see where it’s coming from...it’s odd. I’ll likely take it into the dealer next week because I’m at a loss. (For coolant that is lol)

For what its worth, there is no cooling to the electric power steering system.

Did you find it?

No. I haven’t added coolant for several weeks. It seems to have leveled out and doesn’t leak. I’m wondering if the oil change guys topped it off and it somehow was overflowing? Hasn’t leaked in weeks ever since I stopped adding coolant.

Highly likely scenario
