OEM radiator/heater's hose clamps

[7071 challenger]

Hi everyone

I would like to know if you guys put something between the hose and water pump housing and/or rad to make a good seal when using OEM factory clamps

Thanks!

   I use aviation Permatex on mine, no leaks.
   A little difficult if you you need to remove them.

I use black 3M Weather-strip adhesive. Never had a problem.

I just put them on without any added sealer, though I did wimp out on the lower rad hose my homemade cosby clamp pliers couldn`t squeeze it open wide enough to fit over the water pump neck. I used a regular hose clamp there and did the walk of shame!

I used weatherstrip adhesive after hearing that's what Alan uses.  I havn't had any issues.
