antifreeze(redirected from Antifreeze (engine))
Also found in: Dictionary, Thesaurus, Encyclopedia.
antifreezeA fluid with a high concentration of ethylene glycol or methanol, which is added to car, truck and other cooling systems for internal combustion engines to substantially reduce the freezing point of the coolant.
Antifreeze has long had currency as a surrogate inebriant despite it being associated with acidosis and renal shutdown (due to ethylene glycol), as well as blindness (due to methanol).
In low amounts, antifreeze simulates alcohol metabolism; at high levels, it is associated with nausea, vomiting, seizures, coma or death (at levels above 100 ml of ethylene glycol).
