This thread had me worrying , I went to check out mine 2018 model and it has hex bolts
Toyota changed to hex head bolts for 18 and up models

Nope. the 4R implementation has some kind of actuator controlled by the vehicle.. the only 200-series KDSS valves with any wiring were for a pressure transducer on the early models.Why the hell did the 4Runner get an alloy KDSS valve block and not the 200?
Wonder if it would be possible to retrofit if/when the 200 cast iron valve block is shot? Probably not with different hardline configuration, likely different valving due to vehicle weight difference, etc. but really, why cast iron when it could be aluminum?

A number of people have had welding knock theirs loose when nothing else worked. I’m sure someone could ruin a valve won’t his method but if done right it clearly works.That’s not fun at all, sorry to hear that.
Will the welding process heat up the valve enough to cause issues with the internal rubber gaskets? I guess at this point, the worst case scenario is that it does, but you’d be looking at a replacement valve in either case.
Happy to report I got the second valve cracked loose. I took it to a local shop recommended by some other LC owners and those folks cracked it open using a slightly larger than 5mm triple square bit (size 6). Wanted to share that trick for anyone else with a stripped KDSS valve.A number of people have had welding knock theirs loose when nothing else worked.

@dabebayehu I’d try to find a welder with a ton of experience and maybe provide them some pictures from this thread or the KDSS anatomy thread. If they have an idea what’s going on inside the valve this should be no problem for a good fabricator.
