IF IT hAS Thread locker, use heat. (small torch) gently and it gets soft and comes off. (the red locker is 300f to 500f spec, in the data sheet of it)
the sizes are all here, what heads you have now is anyones guess, mine are torx. T20.
thread locker is so the maker does not get sued for $1billion dollars like toyota was , falls off and leaks and RPM at 3000 all the time and grandma runs over kids, see? Torx also assembles faster in the factory, Phillips stink, I like hex Allen too, an are all sold every one at boltdept dot com.
I have full set of screw pitch gauges,. so know what there , here is my results.
note the metric part mix.
how is this. guess 91 to 95 same, me. (SBEC PCM), do not use Red Loctite, it is too extreme for here. the engine does vibrate so...
this is my replacement TB, mine the bottom 10-24 hole stripped out (PO done)
not sure me if m5 tap drill will clean up the damage., i bet not
helicoil? 10-24 uses
13/64" TAP
drill (0.203) , i think will fail due to thin margins
the 4 screws at near top yellow arrow are security keyed.
the fender bolt head here is a joke, I have huge boxs of bolts/screws here. to test. this was first grab. fits, all these are sold at the big box stores, hardware in the bolt department. under SAE machine screws. , the TPS comes new with screws and so does IAC Im told.
use heat do not break off such tender screws. The body is only aluminum do not over torque them.
m6 are 9ft/lbs only , x12 is 108inch/lbs do not strip them out
#10 or set gently tight, hand tight and 1/4" turn more,max
the TPS can be put on wrong if the tangs not aligned. The TPS must advance full range, TV from 0 to 100% throttle. the FSM shows how and is free.
above MPI not TBI.
