Hey guys. Finally getting ready to replace the PHH on my 94 with 220k. Been putting it off for years as it looks good. It still has the original Toyota clamps and assume it has never been done. I had a catastrophic radiator failure the other day and I’m doing a complete cooling system replacement. I’ve spent quite some time trying to find a pic of the top bolt I need to loosen with no luck . Anyone out there that could send a pic? Thanks

AFAIK there are two bolts. One you can easily see and get to if you just look around, the other is pretty much impossible with the head still on. Most people just wiggle the hard pipe up/down/back/forth for a while until it breaks off (I did this in addition to hitting it with a long cold chisel a bunch of times). Once the pipe is out of the way, you can usually get in there and take the bolt/broken off mount out. YMMV
Back side of the top one from the drivers (left) side. See my red "circle".
And the lower one is on the other side of the metal pipe screwing away from the firewall toward the front of the vehicle. See my red arrow.
For the lower bolt I used this tool with east to get it out. You don't need to put it back in when you are done. Just the upper bolt is fine

Not completely sure I understand your question so...you are asking how to loosen the hardpipe so you can wiggle it around and get that short rubber PHH out and back in?
But, anyway, let me drop this in - a smart landcruiser guy suggested years ago, and I did this and recommend it as a practical PHH solution - remove that hardpipe and ditch it - do no replace. Instead - run a long 5/8" Gates Green stripe from the heater valve all the way around the brake vacuum booster, down and under to the the block PHH connection. Then, getting it off and on is very easy because it's not a short trapped segment. You reach back there and grab a big handful of hose. It does not change coolant system function an any way. You also have some spare "trim&replace" slack available on the end of the hose forever more.
Also - I kept the hardpipe as a handy connector shop piece, along with a long piece of 5/8" heater hose, with a brass female garden hose adapter on the other end, so you can easily flush the cooling system(any car) with full flow hose water into whatever part of the system I want to.
