Blocked Radiator

still losing water and bubbling in the rad and expansion tank

so ive come to the conclusion the radiator is blocked?

anyone experienced this problem?, am i best just getting a new rad or is there something i can use to unblock it?

radiator was blocked up, kept chucking the water out into the expansion tank

new radiator on today has sorted everything, running 100% again

luckily it wasnt the head gasket :)
