The internal-combustion engine has been around for more than 100 years. In that time, we haven't progressed much when it comes to coolant systems and hoses.

It won't collapse and is not adversely affected by vibration or extreme changes in temperature. And the Cool-Flex hoses will outlast your Mustang's engine.
