if the neck is cracked you will need to replace the rad. you can call
me and i might be able to get you a good price, 401-846-6040
what will happen soon is the neck with break completly off, sending
coolant everywhere and dissableing the car. i have seen this many
times. does the neck on your have a metal sleve inside the neck-that is
a more updated rad.
I suspect the neck to tank seam has cracked so further clamping of the
radiator hose is useless. With this in mind look at it again carefully
to see if that is in fact what has occurred.
Some radiator shops can fix plastic tanked radiators, suggest you dial
up the shops in your area or shop the internet for a new radiator.
In fact, I suspect the plastic neck cracks because many persons clamp
down too much. The plastic eventually gives up. Updated version has
metal inside the neck to counter the pressure.
Many radiator shops can replace the plastic tank. Just call around your
area. It costs me $180 to get a new top and complete cleaning for a
300SDL radiator (bringing it to shop). It was like a 3-hour turnaround
time for the shop.

After replacing the water pump on my 89 300E, I now also have a bit of seepage
at the neck. On closer inspection though, it appears to come from the over-
flow hose that comes from the reservoir tank. The seep appears to be coming
from a 'funny' sort of connection between the plastic elbow that is fitted
to the hose and the plastic radiator. Is this a replaceable part I wonder?
Is it possible that some of the reported leaks are from that?
