new aluminum radiator fitted how do you earth them so they don't rust??

[*uwishn*]

as the title say's i have installed the eBay special aluminum radiator,i have been told you can earth them out so they don't rust how do you do this thanks.

Simply find any point where a bolt threads into the radiator, and run a good wire from that bolt (using a ring terminal) to your main earth stub on the driver side guard.

Actually the real problem with aluminium radiators is galvanic corrosion caused by the motor and other circuits not being earthed adequately to the body. What happens is the circuit earths itself via the coolant and then radiator and can kill a radiator in very short time if you are unlucky. The key is to make sure *all* of your earth straps are adequately connected to the body/whatever and not corroded.

These radiators are mounted in rubber mounts so they are actually insulated from the body, this helps stop currents entering the radiator in the first place. Connecting a wire to the radiator and earthing it will only help cause corrosion from electrolysis by allowing currents to flow through the radiator. Keeping the factory radiator mounts in good condition, and using a quality engine coolant mixed at the correct ratio (usually 50%) with distilled/demineralised water ,which is available from the supermarkets or auto shops etc, is the best method to stopping radiator corrosion including electrolysis.

a lead sinker bashed to flat surface and drilled out and this is used as a ,anodal spacer mounting, between The radiator and the crimp join ...so this anode corrodes instead on aluminium... this is what all boats use for ocean to boat earthing.

their is a tablet you can put in them......

Bwahaha a lead sinker? You might have better luck with a ZINC anode champ. LMFAO

[Nathan54321]

yeah suppose when you scratch zincalum gutter's the zinc goes first coz of electrolysis....
