copper radiator vs aluminium engine

[Paul Rig]

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 )
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.

[Paul Rig]

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!

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 LoL

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

Evans coolant?

The Cummins triple-nickel is back! Cummins 5.0L V8 Turbo Diesel – Powering the Nissan TITAN XD

Totally different engine though.

I saw an article in a hot rod type of magazine that featured a Pro-Stock styled pickup truck with a turbo charged Duramaxxxxx i believe it was and that thing was some where i believe in the low 8 sec. range.

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

Antifreeze.

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..
