the bolts that hold the rad onto the Front?..there are 4.the heads are 12mm..Not sure of the thread though...Now if you are talking about the rad shroud,you can use any of the common 10mm bolts/nuts..or Ziptie the shroud to the Rad.

Come on guys, this is easy...
JIS (Japanese Industrial Standard) lists bolts by the shank size, not the heads.
For the commonly used sizes we see most often, it's even simpler...the head is 4mm larger than the shank.
Thus, a 6mm bolt will take a 10mm wrench, an 8mm bolt uses a twelve mm wrench and a 10mm bolt takes a....wait for it...yup, a 14mm wrench.*

The four radiator mount bolts are 8mm x 25 or 30mm long (can't remember right offhand).


*For some reason, the 8mm bolts most commonly found found in American hardware stores do not adhere to JIS specs and will have a 13mm head. This is silly and the reason that I source most of my non-mission critical hardware from junkyards.

And this is probably in the thread pitch thread located in the Archives. Almost all bolts in the engine bay are M8 or M6.

Um, I don't think so.
The three bolts that hold the thermostat housing/hose fitting (he must have a S5) are M6 about 1" long.
