What is the capacity of the cooling system on my 83 Trans Am with heavy duty cooling? Also, for the colder weather, should i run straight anti-freeze or 50/50 coolant and water? Thanks.

str8 antifreeze won't cool like it should, it is actualy the ater that does most of the cooling power if I remember right from what U read. U don;t need to run anything more than a 50/50 mix. .. auto parts stores sell litle guages U can stil right inside the radiator cap and it will tell U the freezing point of your mixture. when I had my talon I was running a 30/70 coolant to water mixture and it ran great and never froze in CT winter

My 383 is in the process of being built right now, hopefully to make it's debut by middle December. . . many more mods to come in the summer. . maybe some experimentations with juice. . have some track times my independence day.

To answer you other question, the capacity should be 17 quarts for a fully dry system. If you are no removing the block core plugs to drain it completely, plan on at least a half gallon remaining in the case.
