So I just now was watching the show Motor Week and learned the following.

For cooling system connections made of plastic like our OEM radiators, the spring type hose clamps should be used, not the screw type hose clamps. The latter can cause hairline cracks to form in the plastic because of localized forces whereas the spring clamps apply force more evenly.

 

Those are frustrating to take off lol. Always in a hard to get to spot
