Jerry Roberts Posted March 4, 2018 Report Share Posted March 4, 2018 Reading in April 2018 Hot Rod magazine ; " A good idea for any aluminum radiator " ... a anti - corrosion sacrificial anode in place of conventional the drain cock . The one shown is Flex-a-Lite brand part number 32060 sold by Summit Racing for $11.97 . Opinions are welcome . Quote Link to comment Share on other sites More sharing options...
ACJCF2 Posted March 5, 2018 Report Share Posted March 5, 2018 If you use any of the 50/50 pre-mix coolants sold in parts houses and box stores, the anode may not be needed. Pre-mixes use de-ionized water thereby reducing electrolysis and residue build up found when using tap water or other water. Jim Quote Link to comment Share on other sites More sharing options...
MackTheFinger Posted March 5, 2018 Report Share Posted March 5, 2018 (edited) Antifreeze can corrode aluminum and that anode is $12.00. I recently opened the hood on a car that had set for about 20 years and the aluminum thermostat housing was almost completely gone.. Antifreeze was nice and clean, too.. There are radiator caps with an anode built in, too.. Edited March 5, 2018 by MackTheFinger Quote Link to comment Share on other sites More sharing options...
Flatie46 Posted March 5, 2018 Report Share Posted March 5, 2018 For some reason I thought this was more of a problem on negative ground vehicles than positive ground? Quote Link to comment Share on other sites More sharing options...
ebruns1 Posted March 5, 2018 Report Share Posted March 5, 2018 I bought a new triple core aluminum radiator for my 1950 Ford F1. $9 worth of insurance on a $200 radiator...why wouldn't you? Quote Link to comment Share on other sites More sharing options...
