June 11, 20224 yr Hi all. My son has damaged his radiator today and after looking at replacements on web they all seem to have an additional port on the top of them . . Can anyone shed any info on what this port is for as the 70 cc rookie does not seem to have it
June 12, 20224 yr Author Hi It seems after some research that the older txt radiators had the thermostats inline and not in the radiator itself. Does anyone know if these older rads are available or could the port be blocked out and the new type used. Regards Neil
June 12, 20224 yr You might be better off taking it / sending it to a radiator specialist to be re-cored. Nothing special about them, they would sweat the tanks off the top and bottom and replace the core (assuming that is the damage.) They might even be able to repair. A quick google found this lot https://www.radiator-repairs.co.uk/radiator-repair/motorcycle-radiator-repair/ not a recommendation
