The technician will drain the cooling system as necessary and remove the hose. An inspection of the radiator neck or thermostat housing it is attached to will be performed.

Hoses will often be stuck to their attachment points. When removing them from thermostat housings and radiators, it is important to take care not to apply too much force as it can damage plastic fittings on otherwise fine components.

There are many aftermarket or universal radiator hoses that are cheaper than the OEM hoses or their equivalents. It is important to order the correct, high-quality hose to ensure a longer lasting repair. While more affordable, the cheaper hoses may be of inferior construction, incorrect shape, or missing provisions for the expansion tank and other cooling outlets. Ill fitting and low quality hoses increase the risk of coming off or collapsing, causing overheating and subsequent engine damage. If a hose has to be modified to work, it is the wrong one.
