I don't fault you for using BarsLeaks. I am using it to keep my head gasket from leaking on my E 300 D, but please, not the old pellets. They only half disperse and the useless half just settles out in your rad or block. BarsLeaks has a new Radiator Sealant that is dispersed in a bottle and can be poured right in. They have a bunch of sealants but the Green lable is the old ground up root in a updated form.
