Hi there,
Radiators have top & bottom tanks, this is where the hoses go, these are crimped or soldered to the core, the core is made up of many tubes or core tubes, these tubes need to be cleaned and often a probe is need to be passed through each tube first to break up the sludge and scale causing the blockage.
