With the continuing shortage and increasing prices of ethylene glycol, several substitutes have appeared on the market.
These substitutes appear with many names and a variety of prices. Recognizing that price is a major consideration when purchasing required materials,
we caution dealers to assure that a bargain is indeed a bargain.
Many substitutes will require increased concentrations for freeze protection and may inhibit coolining capability.
Only ethylene glycol based coolants for aluminum engines meeting the GM 1825M specification are approved for use in Cadillac vehicles. Coolants
which use substitutes for ethylene glycol do not meet warranty requirements.
