Coolant change question

[RebelV8]

I filled my system with Toyota red coolant last year when I rebuilt the engine ( 2.4 ), do I need to change it again for winter weather or will it be ok this year and need changing next year?

It,ll be ok for years to come. No need to change.

What he said.

It stays looking fresh for years... as it doesn't cause the cooling system to corrode.
