I found the following on a list, gtcars.ca ...
It is Subaru's fix for their leaking head gasket problem. They will no longer pay under the warrantee to replace the head gaskets unless the additive fails to work. The official Subaru name for this stuff is: Cooling System Conditioner. Part number SOA635071. The cost is about $1.75. Much cheaper for Subaru than having a mechanic replace head gaskets. The stuff is likely the same as Holts Radweld. Container is the same shape, same quantity (125 ml), same color (blue) container with a red cap, and even has the HOLTS name near the bottom. Also says "Manufactured in England for Subaru of America, Inc." See: http://www.holtsauto.com/products/index.html and look for Holts Radweld I guess someone had to make it :-) It's interesting that Subaru has put some much faith in this fix. Best Regards Dave |
