radiator cleanup



The picture is sideways, could not figure out how to change it. Anyone have any chemical suggestions that will clean this radiator up inside and out where it will be ready for some paint? It's out of a 56 f100

I think caustic soda is what some radiator shops use in a hot tank. The problem is that what do you do with the stuff when you are done. Expensive too if you are only doing only one radiator. Somebody else may know of something more friendly. Just be careful of the waste. Like antifreeze it is probably very harmful to pets and wildlife. Maybe just taking it to a radiator shop would be cheaper and safer. They usually paint it for you too as part of the price.

That thing looks pretty bad. Unless you can have it checked and reconditioned by a radiator shop, I'd look for another radiator. The blue green area is severe corrosion. Usually when you start seeing that the copper fins are beginning to deteriorate.

You need a radiator shop my friend. Even the best looking specimens hide their innards - only by having it boiled and pressure tested will you know. Rolling the dice will get you 15 miles from home with a confirmed diagnosis.

A good shop will get you in and out for under $100

Yes, $100 if the core is not beyond repair. Then don't be surprised if they tell you that it will be $500+ for a re-core. You can buy a new aluminum radiator for about $300. If that is out of your budget I have always had luck with Bar's Leaks. Since your cooling system is relatively low pressure (4 psi vs 14-18 psi on modern vehicles) it should hold you for a while. If it doesn't work then you are only out less than $10 just watch for leaks and make sure your temp gauge works.
