Anti-freeze question

[Brianmckewen]

I have Prestone anti-freeze that has ethylene glycol and diethylene glycol in it. Is this okay to use in my Helix? Also the manual says to use sealant when replacing the mechanical seal for the water pump. What should I use for this? Thank you. Brian.

Use any silicate-free anti-freeze/coolant compatible with aluminum engines. I use Prestone Extend. Do not use any water pump lubricant.

Thank you! I have the right anti freeze then.
