I finally put my ST up on the lift today and was surprised to see completely no weather protection for the engine on the bottom. In the northeast, everything will get covered by salt.. Was there ever a Fiesta model with a bottom pan that I can purchase and retrofit, does anyone know?

When I did my oil change i noticed the same thing. I'd like a flat bottom down there if anything more so for the aero and the MPG increase on the highway. I'm in the thinking/planning stages of making one for myself.

A pan under the engine isn't at all for weather protection. It is for aerodynamics. My focus ST has it. The fiesta is still a economy subcompact. The focus and escape are more mainstream. the fiesta has to meet a price point. The pan is above the price point.

it might be for aerodynamics, sure, but I don't care as much about that as I do getting salt onto engine components. I own a VW specialty shop, and the difference between cars that have the factory belly cover, and those that don't, is like night and day.

I noticed this the day I got my car, I would really like a belly pan underneath the engine compartment unless it has something to do with cooling. The turbo is pretty close to the bottom of the engine behind the oil pan.

EDIT: Just checked with the parts department at my dealership and there is nothing for belly pans for any Fiesta model. Hopefully COBB or someone could fab one for order if there is enough interest?

For oil changes I liked the fact that it didn't have one. I always hate having to pull it off of my other cars when I do service on them.

I suppose it was a cost move by Ford, but be careful just throwing a piece of sheet metal over the bottom of the car and calling it a day. Typically under trays are vented in the proper spots to ensure that air flows thru the radiators and over the oil pan to aid in cooling. Chocking the vent area (i.e. the open bottom of the car) could stall the flow and create a deadzone of air in the engine bay because air is coming in and not going out. There's a lot that goes into aerodynamics and just a flat under tray isn't all there is to it.

As an anecdotal aside; I was at the track last summer and one of the guys made a makeshift under tray once his got ripped off when he went a little agricultural and his oil temps went crazy because of the lack of flow to the radiators and pan.

It is a little surprising that it doesn't have one. But with that being said, I usually end up taking them off my car for one reason or another anyway, so no big deal haha
