LS3 Radiator Overflow port
 
1 Attachment(s)
Have a question in regards to the radiator overflow port that's below the radiator cap - I intend to run this line over to a plastic tank - similar to the factory one. Is that acceptable or is a pressurized tank needed ?

My overflow tank is not pressurized, on my C30 I used the original 81tank and radiator

No pressurized tank on mine. Just a standard overflow tank. It sucks in coolant when cold and pushes some out when warm.
