Zinc Anodes for your cooling system

[69boss429]

When I googled rad electrolysis I also found this on AAPD's site
ELECTROLYSIS PROTECTION RADIATOR CAP
C5ZZ-8100-RC-C

This radiator cap includes a magnesium anode that protects aluminum and other soft material engine components from electrolysis. Electrolic metal (EME) is slowly destroying your engine components. EME attacks timing chain covers, radiators, heater cores, intake manifolds, freeze plugs, head gaskets, thermostat housings even cylibder heads causing premature failures. By allowing EME to attack the sacrificial anode, the Rad Cap" protects your engine while driving or in storage. Fits all years, con

Application Notes: CHROME PLATED
Price: $25.95 each

I talked to Ron Davis about this with their radiators, and ended up not using one

For it to be effective, you'd have to be checking it all the time : when serious electrolysis happens, your anode will be gone fairly quickly, then your radiator.

If you check it, it's being affected, replace it and repeat, you're just on borrowed time and need to address the grounding problem.

Also, most anodes (such as the flex-a-lite) use a brass fitting, not an aluminum one....brass fitting in the aluminum rad is a big no-no

Does anyone have any experiance with Evans Cooling Products ?

used it in my trucks, and now using it in my jbl. hoerr racing sells the thinner stuff for racing.

no problems here, might be nasty on paint though, don't know for certain.

Why?

Mine is fine and has been in it for over a year and a half. I've taken it out quite a few times.

Gents, The protection you need to minmize electrolysis is ensure all of your grounds are well established on the chassis and each electrical consumer is properly grounded . If the radiator is being used as the path to GROUND, the current or potential (voltage) can be checked in the coolant. I went to Griffin's Radiator web site and found this helpful how-to. Dont just guess if electrolysis is an issue for you, measure it, this method works from experience. Here is the link below.

efnfast, Why is the brass fitting a big no-no???
