Antifreeze -- Does it ever go bad?

I found an old container of "Prestone II Winter Antifreeze Summer Coolant" in my garage that looks like it's from the 80s. I'm thinking about pouring it in my Jeep.

Does antifreeze ever go bad?

I have some vintage 80's antifreeze also that I have been using in various engines that takes green.

Good too know, thanks. I think I have a coolant leak, so my system has been (mostly) flushed for me!

pour some in your pups bowl...if he acts a bit strange and has a mild case of the no breathers then it is still good....


Seriously though, I've never heard of anti-freeze going "Bad" or expiring.

Your not pushing the limits of your jeep until your on your side, then something breaks and it's time to go home.

But mine is red! The factory filled it with red

Most times you buy it in a green color though so yeah, as long as it's not a really abnormal color such as brown are some tint towards it should be good.

I can't think of the exact chemical names off the top of my head but they have a different chemical makeup and when mixed they react and produce a brown sludge/gell that gums up all of the coolant ports in your engine, not to mention water pump, radiator and coolant lines. If you go to an autoparts store and buy "dexcool"(orange) And what I call traditional (green) just mix the two together and you will see what im talking about. But they also sell universal fluid which does not react with green or orange. Traditional is most commonly yellow, originally designed to be topoff fluid but it has evolved to be used as more than just top off fluid. Why the two kinds? As car manufacturers realized people don't change fluids as often as they should they started to develop a fluid that lasts much longer than the traditional green coolant, thus was born dexcool(orange) a new organic fluid thy could last up to 100,000 miles without being changed. But why not just not run dexcool in every car? Once traditional has been used in a system that system is forever destined to be traditional, not even flushing the system multiple times can render it safe for dexcool. and once green and orange are mixed you have only days to flush your system before the damage is done, not even flushing the system 6 times and refilling with correct fluid will clean out all of the sludge once the two have been mixed for more than a week

You can test the antifreeze with a test strip. Napa has them. I'd defiantly shake it up before testing and using it. I'm sure that the Silicates have settled to the bottom of the jug.

Poured it in. Now I have to figure out where my leak is. Any tips on pinpointing coolant leak locations?

Make sure all hose connections are tight, and check for any places a hose might be contacting metal as that will cause chafing.
