I am in my Mustang restoration process and may be a new cooling system reservoir is needed, actual is a plastic, generic one.
My first thought was install a SS or aluminum cylinder but I am thinking in not install it.
I understand that reservoir is needed to allow coolant expansion and I made calculation for volume at 80°F and at 200°F to know how much will increase.
Using 50% Ethylene Glycol solution specific gravity at 80°F = 1.077 and at 200°F = 1.038
Total solution in system 16 quarts = 15 lt
1 gallon (3.78 lt) of Ethylene Glycol weights 9.46 lb = 4.3 kg
Density = 4.3/3.78 = 1.13 kg/lt
Mass = 1.13 * 15 = 16.95 kg
Volume at 80°F = 16.95 / 1.077 = 15.73 lt
Volume at 200°F = 16.95 / 1.038 = 16.32 lt
Volume increase = 16.32 – 15.73 = 0.59 lt
Radiator is not stock, measures are 60 x 6 cm, if I left 2 inches (5 cm) below cap empty,
Volume empty = 0.06 * 0.05 *0.6 = 1.8 lt
So I have enough space.
Am I correct?
What do you think?
