Toyota Super Long Life Coolant

[maxgxe]

We have a 2005 Camry LE 4 cyl. with 26k miles. This past week I bought a gallon of Toyota Super Long Life Coolant (the kind that's already pre-diluted 50/50) to fill the overflow tank to the 'full' mark. After filling, I'm guessing there's 9/10 of the gallon still in the jug. Does anyone have any info about how long this stuff will keep in its original, tightly-closed container? Is there a 'shelf life'?

I can't honestly answer that question but it should last almost forever. In that black jug it can't be degraded by sunlight (if that's even possible). Also, it won't be doing any work. There isn't any chemical or mechanical processes going on. It should be fine for when you want to change it a few years down the road.
