My radiator for my R300 has been leaking, it's an all aluminium type with the top and bottom tanks crimped on, so I took to D T Radiators 18 Regent Road Liverpool L3 7DS 0151 255 1672 they un-crimped the top and bottom tanks, made a new top and bottom gaskets fitted them re-crimped it all together using a hydraulic press to get even pressure on the new gaskets then pressure tested overnight all for £50.00 well happy Phil Birch
