Kent starts out the video talking about prevention by using the neck reinforcement kit he has been selling for years. In the case of his own 1990 300SL the neck had not been reinforced and it broke cleanly right in the middle. Fortunately, it happened in his shop when he removed the upper radiator hose clamp! Considering that as well as the cost of a replacement radiator, he has decided to repair rather than replace. The video will walk you through the procedure of repairing a broken neck and “pining” it for safely so there would be no way it could work loose and fall off in the future.

PLEASE keep in mind that all broken necks may not be repairable. If the neck broke in multiple pieces it means the plastic has deteriorated so much that you should not try to glue it back together. Some plastic tanks may be so old and “rotten” that repair should not be tempted. We have never seen a lower neck crack or break. That means that heat (which rises) is a key element in the deterioration of the plastic.

Plastic Radiator Neck Reinforcement Kit
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.

A broken radiator neck can be safely repaired if it breaks off cleanly in the center or aft of the center of the neck. If it breaks off too close to the tank or breaks off in multiple small pieces then we advise that you replace the radiator.
