Ahh, so you've seen the lower grille block done, now what? your upper grille block is still cooling the engine way too much, and temps have dropped below zero. You need a full grille block? well here's where we get started. (note: copying and pasting from previous thread to save time.)
So, what will you need for your upper grille block? Well first, make a prototype. This is probably easier material to find, and gets you ready for a better designed one.
Supplies:
Clear boxing tape
Saran Wrap
Scissors
Friend that's lurking at your house
Jacket
First, I got my friend who was with me at the time to help me keep the saran wrap from folding in on itself while I got the tape ready. But even before that, I made sure that the Jacket was on nice and good.
Take friend and have him take the roll to one end, and the flat-side on the other side of the grille. Then, after you forgot about the tape
, have him hold both sides. Cut some tape, then tape one end to the grille, then cut the other side off with the scissors. Tape all four corners with the tape, then at about this time your friend has to go home (cause he was leaving at the time you remembered about the grille block
) so you do the rest on your own. You probably didn't make the saran wrap perfect, so you fix the problem with tape, stretching, and more tape. You might need to pop the hood to do this correctly. If you can, tape over the block heater cord (optional) so it doesn't flap around while taking a tight turn (this looks odd to viewers who wonder what exactly that cord is for).
You should end up with something like this, a testable, clear grille block that is external, so air flows most efficiently around the grille for best aero (apposed to a block on the inside of a grille.) and still looks stock-like from some distance.
Now we'll see what happens after some rigorous testing is done.
