As the title states, I’m trying to see what thread pitch/bolt sizes the TWO threaded bolt holes in the upper radiator support takes. The location of the upper radistor support, for those who don’t know, is right behind the top front bumper grill, and sits right underneath the area where the hood latch assembly is. Mishimoto’s 25-row oil cooler/bracket uses these two main holes to bolt up their cooler, to which I am going to be running an aftermarket but practically identical oil cooler setup.

The oil cooler that I have, also comes with these two “L” shaped brackets that I mounted to the bottom sides (right and left). However, there’s nothing UNDER the cooler that can be mounted; therefore, I wanted to use something stupid like plastic zipties, just for extra “reassurance”? It does sound dumb, but honestly, the top-mounted bracket on the oil cooler, and the two main bolt holes in the radiator support, should be just fine.

Has anyone else that’s used the same radiator support bolt holes for their Mishimoto oil cooler or DIY oil cooler setup, experienced any loosening of the bolts from that, or any vibration issues? I also plan to use some blue Loc-tite on those two main bolts, so that they don’t loosen over time.

Also, does anyone know what I can use as “fire shielding” or to basically wrap around my braided oil lines? I don’t want them to constantly chafe and/or ride up against all of the contacted car parts, especially metal-on-metal contacting.
