I've had issues with temp creep only when idle when stopped at long red lights. Before I replace anything like the fan clutch I was looking around to make sure there wasnt any obstructions and I noticed ths upper seal in between the front grille and front of the radiator is lodged/fell. Im going to fish it out and try to place it correctly but before I do I thought maybe I just buy a new sealant because this one looks like its dry rotting.

Has anyone had success finding a replacement sealant? Im having trouble finding this part as well as any threads discussing it.

Thanks! This is a 2005 Rocky Mountain Edition btw
 
Google search on here under radiator seal. I used a bulb trim seal. Amazon $10 bucks

Seems like that seal will ensure air is flowing across the condenser, but any air going through that gap will still go across the radiator.
