Freeze plug question


I'm new to the wrangler world, in fact I'm not yet even in it. I am looking to buy a 99 Wrangler with the 4cyl motor. The seller seems very honest and forthright with me. It has 82K on it. He mentioned one of the repairs he has had done was to replace a leaking or split freeze plug. This is an NC vehicle and prior to that was in PA but that has been a few years. Certainly NC isn't exactly a frigidly cold climate in the Piedmont. PA may be a different story. I am concerned that this is a sign of bigger problems. Here's the questions. Do these things happen very often with this model for reasons other than frozen coolant? If this is a result of freezing it raises all kinds of red flags. It seems it would have to be darn cold and have to be a very high percentage approaching pure water to actually freeze. Just trying to get a feel for what this is all about. If it is just a wear and age thing, I'm going to buy it. If it is a 'the coolant froze up is the only reason this happens' then I'll walk - no run away.

That could be because most (I use that loosely) wrangler owners take care of their vehicles. They are like our right hands.
Retired my 94 YJ 4cyl 5spd @ 200K
Now in a 04 TJ 4cyl 5spd CV @120K+
Both as a commuter vehicle in NW, NJ
April 2012.downsized and now a 99er.

That and the fact that anyone that needs a new freeze plug wouldn't be on this forum. They'd just get a leaker and put it down the road or have a mechanic fix it for em.

Bad/broken freeze plugs used to be a much bigger problem in the "old days" as the material and workmanship wasn't what it is today, and every shade tree'r out there building on their mouse motor would send the block out to some local machine shop and it would come back with 3 penny freeze plugs installed by Igor.

If the plug was repaired properly and all the cylinder have proper compression and nothing is leaking, it SHOULD be ok.

But, I agree with the statement above...get the 4 liter.
