copper radiator vs aluminium engine

Im a bit worried I am making a very good battery out of some very expensive parts.
How would I correct a corrosion problem between copper and aluminium (yes I can spell :D )
Could I connect them on the same ground plane to stop this or isolate the radiator.

Well, we spell aluminium the way you do.

Anyway, put in a zinc sacrificial anode in the plug of your radiator and you should be fine.

good idea but zinc tends to leave messy green grease like goop in closed loop systems.
Altho I might have seen it used in diesel cooling system on a Cummings, contained in a oil filter type housing where it conditions the water.

It is just that the Yanks are well-versed in history and agreed with that Brit, Davy.
Davy settled on aluminum by the time he published his 1812 book Chemical Philosophy: "This substance appears to contain a peculiar metal, but as yet Aluminum has not been obtained in a perfectly free state, though alloys of it with other metalline substances have been procured sufficiently distinct to indicate the probable nature of alumina."[89] But the same year, an anonymous contributor to the Quarterly Review, a British political-literary journal, in a review of Davy's book, objected to aluminum and proposed the name aluminium, "for so we shall take the liberty of writing the word, in preference to aluminum, which has a less classical sound."[90]

You're referring to the Fleetguard DC4A coolant filter.

PS.: You sure can spell aluminium, but not Cummins! :lol:

Should we distinguish between people running straight water and those using a commercial product that should already address this problem?

Aside: remember that dyes will persist longer than pH balancing compounds. Change the fluid regularly.

Dam it spell checker screwed me =D> LoL

that does sound like the filter I use to replace.
I was always told to fill with straight water on that particular truck.

Totally different engine though.

acidity and presence of O2 in the system are a contributing factor.

When I bought a radiator from Ron Davis, it came with installation instructions similar to the link posted by Radius Kid . . . except he recommended checking DC and AC voltage and recommended 0.3v as safe for an iron engine and 0.15v for aluminum. Test ALL electrical components including the starter.

I would say a common ground between the components couldn't hurt anything..
