My collection of Behr radiators is growing.

They look good...just plugged up.

The question is...is there a way to boil, acid wash, or some how clean the insides of these?

I have a 300TE, E320 Wagon and a 190E, live in Arizona and seem to have more overheating problems than anything else.

All the necks are solid and you would swear they were relatively new if you saw them.

Thanks.
