hey guys i have gotten a te project car and it has a filthy radiator i have just been putting water in it and running it and draining it out but it is a horrible brown color i think the pervious owner may have used something like chemiweld in it for a suspected leak when it was just the top hose i found. any way what is there i can do to flush all the crap from it ????????????????

Yes, there are radiator flush products out there eg:

http://www.nulon.com.au/products/Cooling_Systems/Radiator_Flush_and_Clean/#.UeT5NqzRKQk

Ive never used one personally, but ive heard great results, not so much from the Nulon branded ones but any rad flush is better than just warm water.

Take it to a Radiator guy .... if it did have a leak and it wasn't repaired properly you'll need to fix it or it'll just fail again.

Here is a nice write up on reverse flushing your system http://www.ve-labs.net/electrolysis-101/how-to-reverse-flush
