No more blown freeze plugs on water pump
#17
There is a TSB for this problem on the 05' so Mitsubishi had it happen enough that they thought is was worthy of a notice to their technicians. The cause of the occurance is purely speculation at this point. Some believe that cylinder pressure gets into the cooling system and others believe it is purely a function of the pump making enough presure to remove the plug. Their have been several here that had theirs pop out and installed a new one with red loctite or JBweld and never had the issue again. What ever the case may be I feel better with it locked in.
In regards to ice in the block, USE correct antifreeze ratio for your climate and this will never be a problem.

I freaking HATE that stupid plug, its caused me more problems! Last year it foking blew out on xmas day while giving some of my cousins a ride, blown out while going to a client for work, blah blah blah, old pump new pump I hate it! I would do three, to make sure it didn't get cockeye'd in there like my replacement plug is now (and covered in jbweld).

I've had that same plug pop too. If it happens again I may actually do this, thx.
Had no idea there was a TSB for it.
Does anyone know what Mitsubishi did when you bought your car in for this?

yes that was the car in the video. the car hit the wall all the way across the other lane because of it. not sue y it popped out yet but its not because of a headgasket issue....
thank god the driver is ok after the crash...

"Freeze plugs" are in the block to plug the holes left in the casting when the block was make so the maker could shake out the sand. Freeze plug is a misnomer.

TTP can you explain more about the weep hole? I think my waterpump is toast, but I also heard about this "weep hole" thanks!

It was my car in that video on you tube..... So after this happened, got the car back to my shop, did a leak down test, and a compression test, and the compression is 135 psi all across the board. I ordered a new OEM water pump a few days ago, just sucks that the damn plug came off at the track, and not earlier in the day while making 30+ pulls on the Dyno!!! Hope it Doesn't happen again!

A weep hole is just where the coolant that leaks out of the water pumps internal seal comes out. When it leaks it shows you that your seal is going bad on the inside of your waterpump and needs to be replaced.

One time, while doing a timing belt job, I had the pulley and timing cover off and the weep hole was in plain sight. I looked up and saw the antifreeze stains around the weep hole so I knew I needed a new pump.
BTW, the freeze plug in the water pump is probably so the pump can be used on other applications, applications that have a pipe that goes straight out from where the freeze plug is.

Glue isn't going to do anything for you. You can use JBWeld but even that is very brittle. IMO, if you're blowing these our your car has another underlying issue such as a leaky head gasket pressurizing the cooling system under boost.
