I know aluminium is a crack hazard but my old copper radiator is leaking out of the seam at the top so I'm thinking of getting an alloy one off ebay.
They all seem to be around 170 bucks but the idea is to get one with an ebay seller who has been around a bit so I can claim warrenty on it if it does crack.
Thoughts?

get a radiator shop to solder the tank back up. aluminium radiators aren't suitable for 4WD's.

I'll look into that I didn't know that was a possibility

Steve got me onto these guys. Just for interest you can see a professional take a rad apart and resolder. Lost art they say.
