Plastic Pan Under Engine Ducts Not Open

[GHNorth]

My daughter drives a '13 EB Flex, so I'll have to get her to look at hers. Of course, that's just another source of dirt for the engine compartment.

I seem to remember reading on the Flex site that whether or not you had the towing package made a difference. I would think any additional cooling has to be good for the PTU.

Hey guys....when I was working on the SHO last weekend, I noticed that the big plastic pan underneath has two ducts molded into it...but they aren't open.

This AM, I saw one on Facebook for sale, and the ducts are cut open. Is this a PP vs non PP thing? Could it hurt to open them to be functional?

My 2013 SHO PP ducts are not open. My 2012 Flex Ecoboost are open. There is some minor ducting pop riveted at the openings to direct air flow towards the turbos. Ford engineers may have decided this was needed based on temperature data for the turbos during heat soak. For the SHO, apparently this was not as critical and saved the cost for this feature. I'm sure you could swap out an undertray or pan from the Flex. Question is whether this has an adverse effect on radiator cooling, i.e. airflow through grill and exiting engine compartment. SHO has an under bumper spoiler which helps lower air pressure under front and reduce aero lift but also increases airflow through radiator/underhood because of the pressure drop. Flex has no spoiler, so may instead need to augment air cooling with the ducts. Hard to say without knowing the real function.

My 15 PP from the factory was all closed up. I accidentally backed over my original one after an oil change and broke it. When I ordered a replacement from the dealership, it was open and ducted like the one described for a flex. I'm guessing replacement parts have all consolidated to the flex one...

My 13PP has the uncut delta. I can't remember which suv we have in the fleet, but one of them has a removable duct an the lower right side that's open. You can always go NASCAR and start small and see if it makes a difference and enlarge as desired, possibly put a temp probe under the hood and do a highway run with it taped shut then pull the tape and repeat. One of the best designs I've seen to date is the new Corvette-designed to pull air in through the radiator and vent from the top of the hood.

As in like functional engine hood vents...?

Yup, like that but the C7 takes it to a whole different level to pull heat out.

That looks like it's just taking heat from the radiator out not the rest of the engine ... I assume that maybe better way of getting a cooler radiator that will make the engine cooler but less dirty.

Noticed Lexus has one of the same cutouts but not a scoop

That would keep the heat that the radiator has just transferred from the engine->coolant->air from being immediately passed back over the engine by forcing it out the top of the hood. Seems like a good idea.

I had a Explorer Sport on the lift the other day, it's the one I recalled having the lower right ducting and about as close to the SHO as it gets. The duct is made to blow air across the oil pan and rear down pipe area

She had no idea what I was talking about, and no wonder... hers is MISSING.

I it really needed? the under skid plate that is.

I ditched (BOTH) of my skid plates/under belly pans years ago.

Other than for FMC to meet fuel efficiency/CAFE standards, as well as cleaner engine bay, I would say "NO" it's not really truly needed in the proper sense.

Mine's a DD so it keeps a lot of salt spray out of the engine bay. It's so easy to take on and off- there's really no reason to leave it off. If it was push pins, or a bunch of 8 mm screws, yea, I can see that.

good point about all the road grime

I replaced mine with a tt Flex one a few months back, both ducts have channels that direct the incoming air flow up, one for the ptu and one for the rear turbo/down pipe. If your looking at doing this do NOT go aftermarket they are junk and very flimsy OEM is what you want DA8Z9910494B is the part number

I finally received the new "under cover" from Tasca Ford, and tried to install it, only to find that the front drivers side capture nut is missing in my daughter's Flex. Must be the reason the cover was never reinstalled. I've ordered a new capture nut (-W716006-S439) from Quirk Ford. Has anybody ever installed one of these? I don't want her to drive 2 hours to my house (again) only to find I need a special tool to install this thing.

No it should just be a twist in capture nut. However, make sure you have the rubber spacer and clip that attached to the vehicle itself as well.

I believe the "clip" you refer to is what I have ordered.
