This is moving very freely so is this made to do this or is it to be fixed to one place? | | | | | Joined: Mar 2008 Posts: 3,750 'Bolter | | 'Bolter Joined: Mar 2008 Posts: 3,750 | I don't think the baffle plate is meant to move,sounds like a couple of spot welds have come adrift. The plate in mine seems fixed in place.
Maybe someone else will chime in and confirm this?
It might be worthwhile contacting a local radiator repair shop to get their opinion too.

I’m thinking either in the center of the fill hole or may be in the center of the top hose opening. | | | | | Joined: Jun 2007 Posts: 120 Wrench Fetcher | | Wrench Fetcher Joined: Jun 2007 Posts: 120 | I just had my radiator repaired at a local shop. My guy said Harrison is the brand name of the tank on top of the radiator(not the radiator as a whole). I'm not sure if this is true or not but he did say there should not be any baffles moving inside. | | | | | Joined: Feb 2002 Posts: 12,029 Cruising in the Passing Lane | | Cruising in the Passing Lane Joined: Feb 2002 Posts: 12,029 | Tango - yer rad guy must be pretty young, Harrison Radiator was a division of GM until not long ago, and made all the GM rads from the teens on .... but he's right that there's no moving parts in a radiator  Bill | | | | | Joined: May 2005 Posts: 8,878 . | | . Joined: May 2005 Posts: 8,878 | If an original Harrison radiator has been recored with a non Harrison core then the "young" radiator guy would be right, only the tanks on that radiator would be Harrison. Perhaps that's what he was getting at?
Otherwise I too thought Harrison made the whole thing.

They are brass plates brazed in place. | | |
