"Use only Toyota Super Long Life Coolant or
similar high quality ethylene glycol based nonsilicate,
non-amine, non-nitrite, and non-borate
coolant with long-life hybrid organic acid
technology (coolant with long-life hybrid organic
acid technology consists of a combination of low
phosphates and organic acids)."
i believe dex-cool would be the alternative? i'll have to double check the jug because i am due for a drain myself.
