Extreem .... could you send me the info on the web link for the anoide again
I think I will buy a bunch to offer them in the rads as a protection unit

THANKS AGAIN DON

You have mail

If it helps I think it is spelled 'anode'.

Question to all...I've been reading the posts on using zinc anodes in engines with aluminum parts. Interesting idea, never would have considered that myself. What happens to the anode over time? Does it simply corrode away and break up into the cooling system if left unchecked? How often are you replacing them? How would someone know by looking at one that it should be replaced? I live in a rural area where our water is "hard" out of the garden hose, and the distilled water debate peaked my curiosity. P.S...this topic is reason #10,989 I think TC is the best group/website in the country...Rob

here's a quick corrosion explanation. the anode sacrifices itself in the reaction. so it corrodes which does not allow the cathodic metals (like your radiator and block and heads etc.) to corrode. hope this helps.

oops, forgot the link. try this one.

dont anti-freeeze handle galvanic problems is not an anode overkill --alum intake, heads etc etc

I'm no expert on cooling systems so don't take this like i really know what i am saying. corrosion control, on the other, hand is a part of my job. overkill with an anode won't hurt anything because it won't allow the other metals to corrode. also i think there are corrosion inhibitors in anti-freeze. so most likely you would not get corrosion anyway (if the statement about anti-freeze is true), but what can it hurt?
I know that you will see zinc anodes on outboard engines to save the aluminum outdrives from the harsh salt environment. they would waste away quickly otherwise.

Troposcuba and all...

Thanks for the replies and the link about corrosion. Zinc anodes seem like a very cheap insurance item for a $5000+ engine with many aluminum components. Kinda like a friend of mine that built a big dollar, big horsepower motor once. Put it in front of a worn out TH350 trans. A week later, his trans blew up, the car sat for a few months while he saved the money to fix it. Then spent more money on the trans, but left the cruddy lookin' 25 year old radiator in. Two months later, he had tranny fluid and coolant mixing freely in his rad, then got mad at the tranny shop because they wouldn't warranty the thing. Insurance is a good thing...
