my heater valve is leaking. Can I replace it with a regular heater hose, or are the sizes at each end different? I'm guessing a new one is not available?

A new one might be available; when I was trying to find a heater valve for my Prado a couple of years ago I looked at one from an 80's 4Runner and it looked a lot like the one in your photo. If you can find the part number it might cross reference to a US model.
Its the same size at each end. Gates make a good coolant hose and they sell the number 1 and 2 HJ75 heater hoses. About $20AUD ea on ebay.
You can also use the Unicoil type hose, same company as Gates and they have North American contact number.
I used these on my 1HZ conversion into my FJ73 to join the FJ heater valve to the 1HZ and they were still looking good after 6 years.

Should be available new as I ordered some a few months ago. There are some GM valves that can be made to work easily enough and quicker to acquire at local parts store. Local parts store should have a book with photos and dimensions of the GM valves. You can remove the valve and replace with hose but your heater will be constantly circulating coolant then. Probably not a big deal up north though.
Available new.
Just looking at the pic again, that looks like an original Toyota hose clamp. I don't think anyone puts those back on so it could be 30 years old.

beno, why can't I start a conversation/PM you?
Is it the hose or heater valve or both?

It looks like the valve, searching interwebs it comes up discontinued #87240-90k01

Because I am not accepting them.
Calling or email works best now as I limit my time and interactions on MUD.
I thought I can see a swollen bit underneath where corrosion has pushed the hose out causing it to leak. Maybe a clean up will fix it.
If you cant get a new valve (and I think you will) , you can possibly use one off another model and connect it with the unicoil hoses.
Heater valve part number 87240-90K01. Shows it being the same as the BJ7* and FJ7*
Correction to the information above since I was working off of memory and crossed my numbers:
87240-90K01 is discontinued.
87240-90K00 is still available.
90K00 is below:
I think this will work on trucks with the 87240-90K01 valves.

I found the right one, will see when it gets here if it really is the right one.
G'Day Fella's,
Coldtaco, what about just replacing the Toyota hose clamp, with a conventional/screw adjustable hose clamp?
This if it works, is only a Band Aid repair (I assume the hose is old and perished), but this may fix the leak.

Yeah I got it fixed, but can't remember any part numbers :-( I really should keep a log book of all the parts numbers I have bought to fix things. Oh well. The HZ ones would probably work but take some creative plumbing.
