Plastic most likely has NOTHING AT ALL to do with the tanks leaking... I've got an all metal 3-core radiator, and the thing leaks on the seams where the metal tanks are. The reason? I keep slamming the radiator bolts on the bottom into concrete plyons/stops/curbs in parking spaces. This causes the radiator to flex. Yes, if the plastic tanks were installed, i probably would have seen the tanks crack first before the seams went, as is the case with the metal ones. So plastic vs. metal? No difference assuming you don't keep scraping your radiator on concrete. -Robert vin 6585 "X" --- In dmcnews@xxxxxxxxxxxxxxx, "bitsyncmater" <david.mckeen@...> wrote: > > Do they really fail catostophically? > The side tanks blow apart? > All the cars I have owned since the 80s have had plastic tanks and I > only had one leak after an engine overheat. > > > Anyway by now anyone still driving on an origional plastic radiator > > should expect it to fail catostophically. > > > David Teitelbaum > > vin 10757 > To address comments privately to the moderating team, please address: moderators@xxxxxxxxxxx For more info on the list, tech articles, cars for sale see www.dmcnews.com To search the archives or view files, log in at http://groups.yahoo.com/group/dmcnews Yahoo!
