Hey, I noticed today when I was changing my factory heater hose out for new Subaru ones, that the factory put a small bead on the inlet to the heater core.

 

Has anyone ever had these leak?  Is it necessary to do this?  If so, what sealer would you use?

 

Thanks for your help or thoughts

Subaru hoses are always installed dry.

 

You can download a free Subaru FSM and see the installation procedure created by Subaru engineers there. They're all over the Internet - you should get one and review the work you're doing and many of your questions will be answered straight from Subaru.

 

I've seen one 2006 Outback EZ30 (6 cylinder) heater hose leak and that was in 2011 when it was very young.
