Freeze plugs

[Crazybobmundo]

Those freeze plugs are going to be hard to find in the USA. Everywhere else should be pretty easy - my machine shop carried all the metric sizes, had literally all but one on the shelf, and that one took all of about 10 minutes to get from the parts shop.

Hey how many freeze plugs are there? Is it only 9? I got them from toyota and they said there is only 9. But I see 11 openings.

In some blocks 2 of em are screw ins.

Hey, do you remember how many freeze plugs there was on the engine total? I ordered 9, at toyota they told me its only 9 total but I counted the openings and there are about 11.

Any clue which ones are freeze plug openings, and How many there are?

Now if I remember correctly their sizes are as follows:
2@ 30mm on the left side
1@ 35mm in the back
7@ 40mm (3 on the left side & 4 on the right side)
1 flat dish like plug in the front.
11 total (which is comprised of 4 different plugs)

The block you bought originally came with a 7M crank.
It is the later year type (although I am not 100% sure that makes a difference...).

According to the Cygnus EPC, here is how they are from the earlier years to the later years:

EDIT - To add below:
I would recommend using FIPG when installing them.
I would also go with Toyota plugs as well for two reasons:
1) They are brass (if I remember correctly, which is better than galvanized steel).
2) They are on the money as far as sizing goes (as previously stated

11432B on my new block are both normal hammer in freeze plugs.
