hi christy! Not sure if you still need this but I was having the same issue w my Mazda 3 and no one had a ‘freeze plug’ in stock. Did more research and found the part number for the freeze plug and proper name - engine Expansion Plug - 9XG0-14-41X0
also known as a Plug Hexagon Socket.

I am not sure why the mechanic did not suggest this. I cannot drive my car until the leak is fixed and NO ONE has the part, not even Mazda. Mazda suggested I purchase a used cylinder head, take it to mechanic, have them remove leaking freeze plug from my car and use the used freeze plug from the purchased used cyliner head to put in my car. How sur are you epoxy will work? Im a girl so I do not know about these things or what epoxy I need. Would my mechanic shop already have the epoxy? The epoxy option would save me as I just paid $1600 on the car last month. Again, thank you so much!
I have replaced these similar black plastic coolant housings (water jacket) that has several inlet outlet pipes on my Chrysler Sebring 2006. They fail and coolant leaks out. For some reason the pressure builds up and blew a hole in mine twice. But ok after i replaced it twice. Same design plastic used here on Mazda i see.
I am needing advice on how to apply JB weld high heat to my leaking freeze plug on 2007 Mazda 3 Speedster 2.3 non turbo. when the car gets warm, antifreeze bubbles through a small hole, no clue how to apply JB weld Your help is so appreciated as I canot use Blu DEvil sealer product and do not want to pay mechanic $1200 to fix.

Hi Kristy, please do not use JB weld to seal leak! On further info since my advice on sealing the leak, another chap on this site somewhere has found the cause and shows some photos of where the leak is. Sorry but u will have to search for it as i can't remember where it is, but it was recent in last month. The actual lead is from a black plastic connector about the size of your fist. It will have several rubber pipes connected to it for antifreeze flow. It is located beneath somewhere where your leak is. Just remove some components where leak is seen, and look for this black plastic unit. Remove it completely, and inside you will find it is broken and thin string like rubber gasket will be damaged as well. REPLACE this black plastic component. It might have about 4 or so screws holding it down. This black plastic melts inside the device causing water to flow out of its chambers and into other divided compartments. Its not a big job, but you need to remove a few components to get to this device. It will not look broken to look at, but its broken inside! So remove it and replace it. It costs 20 to $100 depending on quality and make. Try www.Rockauto.com , Phone the Customer service and speak to them and tell them what i said here to help you locate the part. Use utube video if one exists to replace it. Let me know how it goes.

PS just found the photos and link to your problem search for author dbelcourt 05-18-2020 05:01 PM. This guy has the full right up and 3 photos of this black water jacket. I think that's what its called. Here are 3 photos copied from dbelcourt You will have to remove car battery and look underneath for this device and remove.
note, i have not done this job on a Mazda, but just pointing you to someone else experience on this web site. The photos i just found a copied from there as i could not copy link. Read this guys write up for more info. Remove battery and search under it. You will need a small socket set. Note the electrical connector is a temperature sensor on side of black plastic unit. Unplug it.
look at engine diagram parts exploded. Look at blue and red arrow and part marked in circles X and Y below. I think this could be your problem leak. Just found this photo in another chat here and copied here for you.
TRY this link in Mazda 3 forum.

Good luck
I am certain the leak is coming directly from inside the brass color hexagonal bolt or freeze plug and Ive been dealing with this issue for three months. I am going to use JB weld high heat putty, any advice and how long does it need to set?
You must clean and Dry the area and sand down with glass paper or steel wool to clean area and vacuum the area BEFORE you apply JB Weld. Apply thin layer, then let dry for 3 hours, then apply 2nd layer. I use a drywall fibre perforated tape to add strength. Cut 3 inches and cement it in there. I hope your sure it is freeze plug and not the black plastic piece as i described in previous messages here. Apply multiple thin layers only. You must drain antifreeze so its not leaking from freeze plug area. You don't need to drain all, just enough to stop visible leak as JB weld will not stick to dirty or wet area. Allow 24 hours to dry, the refill antifreeze, if leaks then add more JB weld after sanding.
Watch utube video on JB Weld uses.

All my coolant pours out of this hex pipe plug thing on what looks to be the cylinder head (driver side). It is blocked by a plastic bracket that holds a coolant hose that eventually goes to the heater core. I assume it is a freeze plug?
Any info on replacement would help. Is there a sealant that goes bad, or is it the plug itself that goes bad? Can the leak be solved by simply tightening it?
What size is the plug and what size hex drive do I need? Can I get to it by simply removing the two (3?) bolts that hold the plastic bracket that block it?
Here is another view:
UPDATE: Found a schematic of the cooling system. The hex plug doesn't seem to be part of the cooling system. However, perhaps the coolant leak is not coming from that hex plug but rather from the water gasket below it. I've ordered the part and I'm crossing my fingers that is the problem. I still would like to know what the threaded hex plug is for.
Cheers
your car to run hot? I poor coolants in and they come out of the hex hole as fast as I can poor it in..
Hi christy, i did not hear from you. Did you fix the leak? How?

Here is what turned out to be the problem. The water outlet BROKE on the inside. I know, right? How does a piece of plastic break when it only come in contact with engine coolant?
Anyway, so the whole thing needed to be replaced. You can see in the first photo blow the inner rim that broke off. In the second photo you can see where the gasket blew due to too much pressure (it is quite stretched out from it, too).
What did you call that plastic piece. I have the same issue with a inner peace broke and it blew the gasket. I don't know what I need to ask for. Please help
