E34 coolant leak - can I fix it?

Question

Hi1992 525i I've had since new & maintained by BMW, 116,000 mi.  The car has a relatively new water pump (last major service).Noticed a small puddle of coolant on garage floor yesterday.  Looked into the engine compartment and it's wet at the base of the reservoir (seems integral to the radiator on L/H side).  I do not know if the reservoir is separate/removable or not, but if there is a seal at the base of it, my suspicion is that is what may be leaking.If it is separate, is it a big deal/tricky to fix myself?  I've some experience tinkering with cars and a respectable set of tools.Any tips appreciated.Thanks,Nate

"N Williamson"  wroteTime for a new radiator.  BMW went to aluminum cores with plasticreservoirs and they're crap (although the older ones are better thannewer ones.)  You can even spend more money for a completelymetal one rather than OEM, but it's not likely to be cost-effectivegiven the age and miles of the car.FloydR

Thanks.  I had seen this link in a reply of yours on another subject and it looks encouraging.  Still looking into the do's and don'ts of the forum aside from the FAQ.Nate

I'm going to look into the all metal version.  I plan on having the car another 10 years or so. Thanks.Nate
