Grommet (420) Rd400 1978 Usa

Damaged radiators are never easy to repair, even by professionals. The results can be patchy and quite often lead to more leaks later, or worse, blockages!
Lime scale deposits are also difficult to remove and reduce the efficiency of the radiator markedly.
Sometimes the best option is simply to renew the radiator, and although expensive costs a lot less than the damage caused by an overheating engine.
Replacing all the ancillary parts at the same time would allow the radiator to function perfectly, and would also improve the eye-appeal factor!
