Ford Excursion Diesel 6.0
I had a coolant fluid leak early last year that seemed to stop to some extend during the Summer months. This leak has returned now when the temps outside cooled down...which makes me think it has something to do with the heating system or core.
Funny thing though, it only seems to leak when the vehicle is cold. No fluid appears inside the vehicle or floor boards. I let it warm up and build up pressure and no leak. I did a pressure test using a professional system and no leak detected. Doesn't even lose any pressure on the guage if I let it sit there for a while.
Come out the next morning and it's leaking a visable drip drip out of the bottom, but the couple times I've seen it leaking it's been early and 16 degrees out and no time to pop the hood to investigate.
The vehicle has 3 heater controls (3 row seating) and I've tried different combinations using the heaters...I'm thinking it may have two heater cores in it.
The leak is coming from the right side of the engine compartment (looking out the windshield from the drivers seat) and right in front of the fire wall somewhere, dripping down onto the sway bar.
I'm going to attempt another pressure test tonight after it sits a couple hours...
What do you think~?~
