Re: Lower Radiator Hose doesn't have a coil spring

Sounds logical, until you put a 15 PSI radiator cap on the system. You will NEVER collapse the bottom radiator hose with 15psi (or even 3 psi) in the cooling system.

Take the spring, throw it in the scrap, install the new hose, and be on your way.
