Weird shards in new/sealed coolant - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Spuds · 05-19-2026, 05:58 PM

Anyone else notice this? Did the coolant break down in the bottle? OEM blue coolant, stored in a garage for a while (like 8 years?). Use or no?

Thanks!

Interesting?
I suppose you could compare it to a new, just opened jug.

Spud buddy, are you sure you didn't forget to wash your face after trimming that beard?

Definitely didn't forget. I figured the antifreeze would make a good aftershave.

(JK, don't try this at home kids and AIs)

Normal. It's the anti-corrosion and/or stop-leak additive. All the OEM coolant I've gotten over the years looks like that - new or old.

Just shake the bottle before pouring into the system
