My radiator tank exploded yesterday. This is the third radiator in the past 8 years that I have had to replace. Can you just replace the tank on radiator? If so, where can I get one.
Please let me know,
John |

john, what exactly is blowing?
your radiator? or the overflow tank. you can replace either by itself.
usually what breaks is the plastic neck which connects to the upper radiator hose, I have had 3 BMWs and all 3 broke in that spot. replacing either is a rather easy job, you could save yourself a lot of money doing it yourself.
I have never had a problem with the overflow tank blowing, although I did have a problem on my E36 where the overflow dip tub was causing erroneous low coolant messages. _________________ joe

Yes, the E39 has an especially problematic cooling system. The only long-term solution is to buy the Zionsville system, but it's not cheap. Some say it's cheaper to keep replacing the rad and exp tank every few years as a preventative measure. Bear in mind that the six is quite vulnerable to damage from overheating.
