How do you replace the freeze plugs in a 440?

1) remove old plug
2) install new plug


Does that help?

Are you trying to do the block plugs with the engine in the car? If so, drop the exhaust and starter then go from underneath the car.

Motor in car. Need to know procedure for removing old freeze plug and installing new one.

Look up some videos on YouTube. Usually folks tap up against one edge with a screwdriver to flip it over and then grab it with pliers. Big socket or small seal driver to get the new one in.

The rear plugs can be difficult to get out because the cylinder wall is right behind it, so it won't turn when you hit one side. It usually falls in the water jacket and you have to fish it out with a magnet, crush two sides, then use channel locks or vise grips to pull it out.

If installing in the car, be sure you can get a straight shot at the plug with a socket & extension or it will be very hard to press in squarely. Usually the K-Frame is in the way of the front plugs.

imho i wouldn't replace it with anything but brass

Thanks for the help.

long term permanent repair, or do you plan on any major engine work anytime soon?

if you're going to be pulling the engine out anytime in the near future, but just want to get it TO that point, then you might have luck with one of those rubber plugs that seal up as you tighten the center bolt.

they're really easy to do on the engine stand. really a pain in the butt in the engine bay!

I use a large blunt chisel, hit on one side till the plug rotates in the bore, then grab it and yank it out. drive the new one in squarely with a large socket. I put a light layer of RTV around the edge of the plug, incase there's imperfections in the bore for the plug, but it seems that most of it just wipes off as it slides in

the rubber expantion plugs will work in a pinch but will usually only last about a year somtimes 2 or 3.trying to put those things in while still in the car is harder than just pullin the motor and doin it right.
