On the overheating conversation... One thing I have noticed on our cars is that we have a bar going across the front where the two crash sensors are located. If you look through your grill you will see it. It's a horrible placement, it basically cuts off half the flow of the already small opening in the upper grill. Also, the bar itself is a horrible design, it's not flat but has two ridges on the top and bottom, probably for structure but I'm assuming it creates a ton of turbulence for incoming air.
At first I thought they where the ambient air sensors, like most cars have in that location, and I was going to relocate them and remove that bar. However I looked up the part numbers and they are the forward airbag sensors.
The other odd thing I noticed is that the Euro Fiesta ST's DO NOT
have this bar or sensors in that location.
Here are some photos of the object I am talking about. You can really see how much more open it is without the object on the EDM version.
