Coolant

[RonS1985]

I know this question might seem like a "You-should-know" kind of question but I have misplaced the specifications manual. Does anyone know how much coolant a 454 should take? It overheated last week because I threw the belt. I've put 2 gallons of anti-freeze in her so far and that is after putting 3 gallons of water. So far I have no signs of it being full and no leaks. I know it's a big motor but...geez!

first, water and antifreeze should be mixed 50/50 before putting in radiator

I know. The first 3 gallons of water were just to get me by when it broke down.

My chassis manual says 22.5 quarts; 5 1/2 gallons of 50/50 coolant.

Yup, about 22 quarts for mine as well.

In his case I can't see how it matters much if it is mixed before or after you put the water / coolant in the radiator. I would think within just a few minutes or miles the mix would take place. If you are just topping off then to assure the proper balance it is better to pre mix.
