Are molded radiator hoses better than flex hoses?
Flexible hoses are the one-size-fits-all variety. Available in various diameters and lengths, flexible hoses can be bent to fit a wide range of applications.
Molded hose is like original equipment hose in that the hose is molded to fit a specific application. This simplifies installation and gives a perfect fit (though some molded hoses do have to be
trimmed to length prior to installation).
Regardless of the type of radiator hose your customer wants, do not forget to recommend new clamps. Original equipment spring-type clamps lose tension with age and may not seal the hose properly. Worm-type clamps are much stronger and easier to install.
