Hi Vicki
Congrats on wanting to tackle the Mazda,
My B's are 1992, and i dont recall any rubber freeze plugs, so help me out, with the year and model and engine if you know it. Then post a picture of where this freeze plus is supposed to go or a good description.
When you are talking about side of the engine they are as if you are sitting in the drivers seat. ie the right side is the passenger (assuming US car) and left the driverside.

Vicki - what engine, what year, and which side of the engine? I've had the top end of my B2200 (1988, 5-speed) apart, but also had a shop remanufacture the engine back in 2020. A freeze plug on the right side closest to the starter leaked, then blew out, and they replaced the freeze plug under warranty. They used a hammer-in type of freeze plug.

However, the rubber ones are simply installed after the surface is cleaned up, then the nut tightened, expands the rubber to seal. See

Here is a couple of pictures of the B2600i engine block (must be what you have according to your Radiator Hose thread) so you can see what you're dealing with.......keep in mind that if you are replacing an original steel freeze plug that has rusted out and is leaking coolant, then you will need to completely remove that rusted freeze plug in order to install a aftermarket rubber style freeze plug and not have it leak also!
Personally, I would install a new steel or brass freeze plug instead of a rubber one.......and remove whatever is in the way to do it correctly.

Anyway, here are some pics of the engine block......

Hi Alex. Thanks for the pics. Im a friend of Vickis. Actually this is my truck. Are you able to post any pics of the rear of engine also? I got the rubber one installed no problem. Had to fix a broken belt. Got everything back together, started filling the coolant back up. After almost a gallon I looked underneath to see if it was leaking. It was but it was coming from under the intake somewhere and it appeared to be coming out the bottom of bell housing. So im wanting to know if there is a plug in the rear of the block anywhere? Any pics and info would be most helpful.

On the engine block, 10 freeze plugs total......

And they do rust from the inside, if the coolant isn't ever changed and/or water was added in place of antifreeze....

Thanks Alex for all your pics, info and your time. it is all very helpful. One more quick question. When the original plugs are installed. They are tapped down past the surface of the block, correct? In other words, I shouldnt feel the edge of the plug if i run my finger over it.? There are a couple I cant see, but do feel the the plugs edge with my finger. One of them being the rear one.
