pink coolant shelf life?

[tarbasd]

Hi,

I have some pink (Super Long Life) coolant that was opened about two years ago. Can I use it in a radiator flush?

Yep, as long as the cap was on the jug.

Its good for 100000 inside your engine, so ide imagine you'll be alright.

Yes, it was. So should I take these two years into account when I determine the time of the next coolant flush?

BTW, the initial fill is good for 100K, but after that they recommend flush at every 60K.

Unfortunatly, I am very aware the coolant change intervals. The more likely scenario with newer Toyotas is that you will change your coolant as often as the water pump starts leaking. Waterpump replacement might as well be performed as a 45k mile service lol.
