Hello all, the side tank gasket starting leaking, i.e., between the plastic side tank and core. Has anyone had any luck with radiator shops replacing gaskets or servicing their radiators. I pose this question with the recent discovery that the Behr radiators are NLA. I am hopeful that my factory radiator can be serviced and perhaps last in till a suitable replacement is available again. I would like to stay away from the Nissens replacement for as long as possible.
