My brother replaced a weeping freeze plug in my '55 President today. He
said when the plug came out, no coolant followed it. The bottom of the
block is totally sludged up! Befor the weeping plug issue, the engine was
running great with no overheating issues and the coolant remained clean.
I'd like some imput from some of you experienced and knowledgeable guys.
Would you attack the sluge if the car was yours? What would you use to
remove it? I've heard that straight vinegar will dissolve it? The good
DuPont stuff can't be pruchased any longer.
Thanks for your thoughts (in advance)

Take all the plugs out and use a coat hanger to free the sludge. A
meesy but important job.

SASCO still has the old Studebaker flush for about $5.00 a can, N8
and I have used a few cases. We use the wire trick, than use the
Studebaker flush.

Here's the drill...
Get one of your children to observe and learn (substitute a neighbor kid if
necessary)
Jack the car up properly and support it with jackstands.
Dress up in a rainsuit with swim goggles or a snorkel and mask...
Disconnect the battery cable.
Remove the starter motor.
Remove the drain plugs out of the sides of the block.
(option 2, highly recommended, but a total pita)
Remove all the side Welch plugs.
Take a hose with a spray nozzle and start digging with a coat hangar
everywhere in the water passages you can find and reach whilst spraying and
taking a sludge bath. Blast all that crud out of there and onto your cement
driveway, staining it rust color.
Reinstall with new plugs and install new anti freeze.
Reinstall starter and hook up battery cable.
Refill coolant system with 50-50 mix of a good anti freeze (not straight
anti freeze).
Cross fingers.
Check for leaks.
Remove old clothes and donate to Goodwill for a tax write off.
Pay kid for helping (even though he did nothing).
Then, for the next time, or the next Stude.
Go find that kid and have him do this job for you......

I have used the white vinegar as a soak, once I have used a wire to dislodge
all that I can. If you do this,first use the wire and then flush with the
appropriate flush, then use white vinegar and block off the radiator. In
other words pull the hoses off. Fill the block with the vinegar and let it
set for about a week. Then flush with some baking soda/water. I am always
amazed at what flushes out. Just don't let it sit in the heater or the
radiator. Or this is what the old guys use to do to get the block as clean
as possible.
