CJ Coolant Overflow Bottle - repair or replace?

I'm the orig owner of my '84 CJ-7. The stock overflow bottle lasted nearly 20 yrs - it finally cracked and I replaced it. I've now gone thru two "OEM replacement" (aftermarket) bottles, and both have cracked after not a whole lot of use.

I could attempt to repair the crack in the plastic, or could buy yet another OEM replacement, but I'm thinking it may be best to go with something else altogether. An aluminum bottle would be nice, but then it may not be easy to see the coolant level.

For those who have had issues with repeatedly replacing these cheap aftermarket bottles, what better solution have you found?

If you've repaired the plastic, how did you repair the plastic?

Thanks

Mine hasn't had one since I bought it 2 years ago. Runs fine, no overheating.

Mine didn't have the lid and was empty when I bought it. I finally found a lid that fits from Oreily but I forgot to fill the bottle. It hasn't needed it and runs cool. But I will fill it soon just in case. My old timer retired mechanic friend told me that I didn't need one and to just check the radiator level when cold every once in awhile like in the old days. I'm lazy though.

My CJ didn't have an overflow bottle from the factory. I found one in a junkyard that would work. I can't remember what I pulled it out of.

both the radiator overflow bottle and windshield washer bottle on my 1984 jeep were cracked.

i tried to repair the radiator overflow bottle, did not work, so it has not had one for years,

but i do check the coolant level from time to time, as the coolant will expand out, the bottle was there to catch the overflow and it was sucked back in when system cooled down. Otherwise the overflow goes out on the ground and you lose it.

check your manual and be sure you have the correct psi radiator cap,
caps do go bad and will not hold the coolant in as the spring gets weak, a new cap is cheap insurance to keep you from losing your coolant..

How about going with something like this? http://shop.advanceautoparts.com/web...7CGRP2014_____

I'm not sure what tomorrow will bring, but it can't be any worse than what I've already been through.
