Rear on the side, or rear on the rear. (your rear really cares about that one!)

Yeah the belt screeching was probably the frozen water keeping the pump from spinning which in turn destroyed your belt.

For the record, the "freeze plugs" aren't there to protect the engine from damage due to negligence. They're there from casting the engine.

Everyone calls them freeze plugs because they do tend to pop out once the engine has frozen up but VERY often the block will also crack.

Replug it and pressure test. If there's not enough access to install a freeze plug you can use a rubber expanding plug they sell just for that purpose.

I know from bitter experience that rubber freeze plugs don't work on the back of the head.

Head has to come off to replace it.

So, have you figured out how you were so far off with your antifreeze "mix"?

Firestorm500

It was protected down to 50 degrees above zero.

LAF1269

Probably down to about 32.

Larry's XJ

Ha Ha. When I first read I thought you said 50 below, I thought how would he know that?

Worked for a guy that bought some anti-freeze that froze. IIRC was unmarked jugs, might have been re-cycled, dunno

Firestorm500

He paid money for so-called antifreeze in unmarked jugs?

Wow.

It could have been pee that was dyed green.

Moot point. If the bottle was frozen, and coolant is running out, somebody made a mistake. Moving on, In OEM Cherokee Teck, the diagnoses/repair is the issue. Especially if a guy just lost his block, towing the jeep. (btw there is a specific gravity chart in my sig. that anyone could use with a regular hydrometer to find their level of protection)

Freeze, or "expansion" plugs can indeed save the block. Ice can flow.....Put an egg in your hand, squeeze and see if it breaks. Cracking a cylinder might be harder than it seems with equal, inward pressure.

firehawk618

They can but are definitely not what they're intended for.

I agree the cylinder might be hard to crack, but the external side of the block will be much easier to crack.

The problem isn't really the ice which increases in volume approximately 9%, it's the hydraulic action on the residual water that hasn't frozen yet which can't be compressed. Pressures can go really high.

NOT a "moot" point. There may be a lesson to be learned by someone.
Was it 50/50 but thinking it was straight, and diluted it. Had it just been flushed and residual water wasn't accounted for?
Still a valid question, don't care if you think so or not.

My mistake Larry, I can be too blunt. I honestly didn't mean any offense, I see how that looks. The OP has a sad, ugly plate in front of him none of us wants. When or who messed up the ratio doesn't seem to be the issue now.

9% turbo Reakkly? I'm gonna wikipedia that when I sober up Monday. Besides a few engines I've repaired plumbing. In 89 when Siberia went to San Deago, I repaired 29 blown pipes. We here are not geared for that arctic stuff. What I saw was the exterionus outer, less massive would freeze, then push into the more solid, more massive, where then something needs to give.

Anyway the OP has some chance, and Larry, I could have worded that better!

Larry's XJ

Well, I may have been a bit harsh myself.

Having froze a radiator decades ago, I understand mistakes.
