I sure wish i would of known when i bought my [Shania] - name i use for my 560 that the weakest part on a Benz is the part where the top rad hose is mounted to the neck with the hose clamp and that a person should put a piece of pipe inside it so when you tighten the rad hose it doesn't crack and break the neck . Well low and behold here i am now with the neck broke off and have the rad hose clamped on to the rad with only mabye a 1/4 of an inch and mickey moused to hold it there with wire. I'm sure it was cracked when i bought it. So what's my alternative buy a complete new rad? she 's a 86' Louis Caroline Alberta Canada
