I wasn't quiet sure whether to post this here or in the 60 section but since this is technically for a 12ht I'll start here. I'm looking for a replacement BVSV for my 12HT. This operates the idle up when the engine is cold. I know the correct part is no longer available but I believe there is a replacement part that operates in a close enough temp range. The original part number is 90925-05052. I tossed my broken one I think so, I don't remember what color it was. I know the colors on the various ones dictate their operating range. I remember reading a thread a while back referencing the temps and colors but cant seem to find it and it's making my head spin. I also don't recall which ones open or close at temp so that's making it more confusing for me as well. The one I need should close at a certain temp and normally be open. These bi metal switching valves were on all models of gasser and diesel cruisers and I had this one laying around from a 2f that I used to plug the hole until I find a suitable replacement. It is 90925-05046 Thanks in advance

Decided to conduct a little experiment. This little bvsv I have here appears to be toast. The water was at 210 degrees at the start of the test and it never closed or held vacuum.

Hey @roma042987, how did you end up going with finding a suitable replacement. Im in the same situation with my 12ht and have been enquiring at about every wrecking yard to see if they have a 12ht for parts or whether they have the KE70 corolla which also carries the 90925-05052 part supposedly.

I haven't found a suitable replacement.

So there seems to be a lot of similar switches but no one knows their temperature range.
Would the 12HT be vastly different to other engines?
I seen some purplish used ones for sale if that's the correct colour for 12HT.

ahh so then it would probably be purple in colour, @roscoFJ73 where have you seen the purplish ones for sale?


Here . It has the same part# as Onur suggested 90925-05035




I saw someone had a big batch of used ones on ebay also

If the info in the second post of below thread is correct then those will simply not work. perhaps we could get @OSS to share where the info about the temps was sourced.
