Can anyone who has installed Evans coolant let me know if they changed their radiator cap at the same time? According to their instructions the cap should be 7lbs for radiators with a cross flow system and a 13lb cap with a top/bottom system.
What I don't understand is if the coolant doesn't boil or overheat does this render the overflow tank void?
The instructions also go on to state;
"For applications where 7lb cap is not available or cap location is on the pressure side of the cooling system, the standard cap may be used".

Would you describe this to be the setup on a 289/302 with a Harrison overflow tank? I can't load pictures but you can see my setup in my gallery.

Regards.
