Smile Cooling system capacity

Anyone know the cooling system capacity for a 69 Camaro 350 w/ac

I can't find in my old manual and need it to find the amount of antifreeze to use. (any antifreeze tips)

Thanks

Re: Cooling system capacity

Cooling system is 17 quarts. I use Peak 50/50 mix.

Would this be the same capacity as a '68, with a 327, 2bbl carb? Thanks

Re: Cooling system capacity

I like the 50/50 pre-mix stuff also....at least you know the blend is right

BUT, if you plan to mix yourself....be sure you use distilled water, not tap or hose

This is crucial in my book. Having had my fair share of diesel engines apart and seeing how tap water leaves deposits out of the water baked around liners, I won't use anything but distilled water in my cooling systems. What's a gallon of distilled water cost.... less than a $1?

Experience...... It's what you get when you didn't get what you wanted.

Re: Cooling system capacity

when I bought my champion radiator I was told not to use well, city, or distilled water, but to use drinking water purchased from walmart

Re: Cooling system capacity

50/50 is not ideal for cooling. Great for freeze protection

Pure water is best but you do need coolant for pump lubrication and anti corrosion.

50/50 gets you freeze protection to -37* F which very few if any of our cars will ever see.

I run 30/70 which gets freeze protection to -17*

Boil over temp is also increased slightly with higher percentage of coolant however this increase doesn't mean much in a pressurized system.(pure water boils at 250* in a 15 psi system)

"You should only use as much anti-freeze as is necessary for your climate and operating conditions"

ANTIFREEZE % WATER PROTECTION AGAINST FREEZING *PROTECTION AGAINST BOIL-OVER
30 70 -17C 121C
40 60 -23C 126C
50 50 -37C 129C

Re: Cooling system capacity

I have found that once the system is empty, add two gallons of antifreeze and then two gallons of water, until full.
