A sturdy radiator hose should deal with extreme demands of different types of heating and cooling systems, so make sure you take operating temperature range into account. You can also find options that are resistant to antifreeze.

Some flexible hoses contain silicone, and others contain rubber lining and high tensile synthetic textile reinforcement. Internal and outer diameters can vary significantly. Replace your old or damaged radiator hose on your own and save cash in the process.
