Car Forum / Australian Car Forums / General Car Topics (Australian group) / January 2008Radiator core cooling fins rotted-out
They say this is due to electrolysis which occurs due to constant re-circulation of coolant by the pump. The voltage then circulates thru the tank and core causing destruction of the emitter or -ve electrode. Large areas of the rear side of the core had cooling-fin destruction. They just fell out like dirt. I had seen a Falcon radiator do this, only worse. That vehicle was stationed at a light house. Probably direct corrosian due the salty air.

Isuzu truck I used to drive suffered cooling system corrosion and some "expert" suggested earthing the radiator, I don't know if it worked as I changed jobs. Daryl > Isuzu truck I used to drive suffered cooling system corrosion and some > "expert" suggested earthing the radiator, I don't know if it worked as I > changed jobs. It generally does. You can test for electrolysis by measuring voltage in the coolant with a multi-meter. Earth the ground probe and stick the positive probe into the coolant in the radiator. If you get a positive voltage reading, you should earth the radiator. -- Regards, Noddy. >> Isuzu truck I used to drive suffered cooling system corrosion and some >> "expert" suggested earthing the radiator, I don't know if it worked as I [quoted text clipped - 10 lines] > Regards, > Noddy. Unless its very clean distilled water. The water needs to have some form of impurity to conduct electricity well. Salts good for adding but kinda defeats the exersise somewhat. ;o) > Unless its very clean distilled water. The water needs to have some form > of impurity to conduct electricity well.

I only post that as my old next door neighbour used to flush every last morsel out of the system and fill with distilled water, dunno why, siolly old buggar never ran coolant either, mond you he was only driving an old 1.0 Escort Van > >> Isuzu truck I used to drive suffered cooling system corrosion and some > >> "expert" suggested earthing the radiator, I don't know if it worked as I [quoted text clipped - 14 lines] > impurity to conduct electricity well.

Only became apparent after removing it due a split top-tank (plastic). While previous owner's maint is a mystery, its only had proper coolant last 4 years.

Al  SignatureWhen schools of fish were studied, it was found that the leaders had brain damage. We, the public should therefore demand a similar study be carried out on our leaders. http://kwakakid.cjb.net/insult.html > > > Isuzu truck I used to drive suffered cooling system corrosion and some > > > "expert" suggested earthing the radiator, I don't know if it worked as I [quoted text clipped - 9 lines] > Electrolysis?

It's more fun to insult everyone. http://kwakakid.cjb.net/insult.html "Albm&ctd" <alb_mandctdNOWMD@connexus.net.au> wrote in message > Electrolysis?

"Cure" appears to be to spray neat diesel on the thing while it's relatively new. Apparently the film remaining is enough to defeat the problem - whether the fins are copper or aluminium doesn't seem to matter. Suggest calibrating oil if the smell of diesel is a bother:-) I wasn't told whether whether doing that later in the devices life is successful, 'cause I didn't ask,I guess.

Ofcourse thermal cycling will ultimately take it's toll regardless on those cores. > >> > Isuzu truck I used to drive suffered cooling system corrosion and > >> > some "expert" suggested earthing the radiator, I don't know if it [quoted text clipped - 22 lines] > successful, 'cause I didn't ask,I guess. > The Nivas radiator is pretty good in that respect, but then I've followed a few smoking GC magnas along the foreshore roads. Not allowed on the beach with your private 4WD here unlike further North. Not allowed to even wash it with town water and hose off salt spray. Imagine that still holds true with our overflowing local dam. We thought it was bad in Communist countries? Al SignatureI don't take sides.

"Droughts and floods at the same time" he said, and people said he was going mad. Well who's laughing now??? Not the Qld'ers who are forbidden to hose floodwater off their cars because of the drought. |
