Charge Air Cooler weep hole

[CHRISTOPHER S CASTLE]

Anyone drill their CAC if so what is the simplest way to access it. I pulled the grill yesterday and could not get where I wanted to.

Charge air cooler. Aka intercooler

Why would you want to create a leak in a sealed system, and lose boost?

The F150 Ecoboost forums recommend drilling a small hole in the bottom of the intercooler to allow condensation to escape. Apparently there is an issue with the system being "too" sealed and water can build up.

I have not seen anyone do this with an Explorer. FWIW, the F150 uses different turbos and intercooler/piping than the Explorer/SHO.

Best way to check if your vehicle is affected by this is to dismount the intercooler and see if anything drips out...

Yes, intercooler is a little more buried on our vehicles. So that is why I was asking

We owned an '13 F150 Ecoboost and yes I did the weep hole and rusty water came out.

Radiators and intercoolers are aluminum, so the rust you speak of must be mistaken for oil mixed in with water.

I agree, the details! I also did the vent to air free mod and really enjoyed the blow off sound. It probably isn't recommend but I traded it at 100,007 miles...the computer fried! $1700 and the air and radio never worked again. The Dealership didn't want to work on it cause it was 7 miles over the warranty (we bought it certified with 17k miles). I did enjoy it very much, easy to work on expensive to keep up with. We have a 2014 explorer now 3.5l n/a.

Thank you

Either way, the hole + gravity + pressure allows it to escape. I understand creating a hole in an air tight system goes against the laws of physics. Installing a catch can is probably a more logical solution. The oil blowby and crankcase pressure is much higher in any boosted application.
