[CigaR007]

So I have completed the first aero mod on my 2001 Toyota Echo.

The lower Grille Block consists of three uncut foam pipe wrap. They were simply inserted and are being held by nothing else but the foam's natural expansion.

The upper Grille Block is partial and is composed of open cell tape that has been cut to fit the Grille design.

Open cell tape has also been used to insulate the existing gap between the headlamps and the hood.

After the installation, I went for a drive on the highway and the coolant temperature was stable at 190 for most of the trip, except towards the end when it rose to 202. I didn't hear the fan come on but I had a feeling it would continue to rise; but it didn't.

Should I leave an opening on the lower Grille Block just to be on the safe side ?

Thanks for the input !
