Darn it if I didn't break something... Timing Belt Swap
Trying to do a timing belt today and my thermostat housing into the block was stuck and I finally got it out but it broke off the o-ring section and part of the main housing stuck in the block. I think it is called the Water Bypass Housing.
Anyone know where I get a new housing? Not the part the hose connects to, the part the thermostat seals to and has the 2 bolts that holds it into the block.
Not cool to break!

Got one from my friend who works at Lexus. $97 dealer cost and got it next day.
It IS a new design, functionally the same, but the design is different. Mine is just over SN 4700, so it is a very early GS400, made IIRC in Sept 1997. So I am not surprised the part got a redesign, the original one had a fair bit more machining to it, the new one has much less.
For giggles I will see what price Sewell can get on it and let you know. But by all means, when doing a timing belt swap, be careful on this part! My friend recommended I use brake caliper lube on the oring to make sure it doesn't happen again. He does all of them that way. I used Anti-Seize, so I hope it lasts till the next timing belt swap!

I did tap on it with limited face hammer,nothing helped. I worked on it for an hour and a half. I tried pb blaster, prying turning, pulling, tapping on with hammer and pulling, it was just not wanting to come loose, I ended just prying in the wrong place. It had a fair amount of buildup in the o-ring groove, so my guess is it had a nice ledge built up. Maybe if I kept at it I could have, but I didn't forsee the part breaking, so for those who try, be careful, don't pry!
I put anti seize on it when I put it in hopefully in 90k I will not have an issue again....

Sewell shows the same part for $78, but I would have to pay shipping and wait, I was able to get this one next day but I had to drive 200 miles to get it and get back home.
Didn't need a balancer puller, it came off with a gentle pull. Apparently this is really common. Love the tight exact tolerances!
