Plastic Radiator Neck Reinforcement Kit

This is a HUGE problem - and if neglected can lead to catastrophic engine failure! Mark my Word...

ALERT! ALERT! 10 years after I first started warning about this, I saw it again in my shop on Feb. 20, 2011. Seems to be happening even more now as these radiators age. I loosened up the upper hose clamp on this 123 300TD radiator and it just fell off.
