Chevelle or Malibu Radiator Hose, Lower, For 283ci W/O Air Conditioning Or 327ci With Air Conditioning, 1966-67

Many of the lower radiator hoses we carry do have a spring in them; however, we supply several that don’t. The spring was originally installed in the hose to speed up the coolant fill operation during final assembly at the factory. The spring holds the lower hose open for the quick pressure fill of coolant. Once the Chevelle Or Malibu is off the assembly line the spring has served its purpose. A properly operating cooling system no longer requires the spring after the assembly process. The normal state of a cooling system is a pressure condition; around 14 to 18psi. Always trust Ecklers for all your Chevelle and Malibu performance and restoration needs!
