86 Corolla Bolt Size? - Toyota Nation Forum : Toyota Car and Truck Forums

I'm pretty sure 2 bolts are used to mount the front exhaust pipe to the manifold in a FWD 86 Corolla but does anyone know the metric size of the bolts?

Should be a 14mm, you working on an SR5?

No,It's a LE sedan...actually need the thread size and length so i can have new ones ready to bolt...

Oh my bad lol, that i dont know, just grab a bunch of random bolts and start threading them in to see what fits, then go to a store where they specialize in bolts and they can measure the thread pitch on the spot(or if you have the studs that were in the manifold to begin with), as for length 1"1/2 maybe 3/4 should do it, if you got to a dealership to buy new studs theyre not that expensive, also studs from th dealer have a hiher heat range, bolts you buy will probubly snap when you try to removing them from heating up and cooling down all the time, they get brittle

I appreciate you taking the time to respond...I just thought if someone had a quick answer to the size of the bolt i would have them on hand as the bolts being removed are 20+ years old...the car will be on a lift and rather than have to run out to a store it would be nice to have them "in hand" and ready to go
