York Premix inhibitor

[Chillmac]

Hey all,

Does anyone know if the York premix inhibitor has a shelf life for the YVWA?
I got some last year about 12 months ago and I need to use some now, so was wondering if the couple gallons I got last year would still be OK?

They are sealed and have not been open. p/n 013-04129-000

Thank you Jay,

I was just a bit apprehinsive about using it. I guess the only this that could go wrong is that the temp could increase in the IGBT's

Make sure that it is the light blue/cyan blue fluid. Do NOT use the dark blue. Throw the dark blue away. Don’t use it anywhere...except where you want bacteria to grow.

And they also recommend using their cleaner to flush the coolant loop before adding the new light blue stuff.

We havent seen that in writing yet, but we are doing the same.

Is their a part number for their cleaner?
