We have a NEW Nissens radiator for sale in the fast lane for $215.00... assuming you have a late '80s 126 chasis.
I have used these radiators before when price was an issue and they seem to be a very good alternative to the OE unit.
I have had great luck with them.
You can order right from the top of your screen. It will be at your house in a few days.
I have seen people try to repair these...Why would you risk overheating your car?
