My radiator has a small leak in it. There isnt a puddle of antifreeze on the floor, but there is a slow drip that has been going on for mounths. Do you think that Alum-i-seal will work. It is suppose to plug up any leak in an aluminum radiator. I also plan on using some Purple Ice, Anybody have any experience with this stuff? Thanks

 

I would consider the alum-i-seal a bandaid fix to get you home before you actually go and repair the radiator. These radiator plugging agents might fix your leak, but they are also capable of plugging the radiator itself.

Alumaseal says that it is a permanant sealand as well as a lubricator for the water pump. They also have a guarentee against any damage. Plus they have been around for 75 years. They sound like they may have a worthwhile product. I guess I can try it and just keep an eye on everything. Can I use it with the purple ice? Thanks
