corrosion in my radiator

I picked up a radiator for my model a and ran it last fall and about 10 times this year and i drained my fluid out and it was extremely dirty and corroded last year it ran on average 180 and this year its running around 205 everything is the same water pump fan timing.... does anyone have ideas of things i could try to clean the water up and run cooler....

i have heard run distilled water does anyone know

 

your motor might have been alittle dirty. was the motor ever like cleaned and rebuilt? if so if might just be build up from inside the motor and just running it. id flush it a bunch of times and maybe before i did that i would test the thermostat it might be sticking from the rust and stuff.

 

Have you thought about adding a coolant filter? I put one in my Comet and it worked wonders.

 

i have been/still am fighting this to some degree on my Newport.

core the radiator and either try to flush the block, or pull the soft plugs and blast it out with detergent, or put a piece of ***** hose over the upper radiator inlet and periodically (when the temp starts to climb again) pull the hose and empty the ***** hose.

you would **** if you saw what i captured from going into my radiator with this method after driving around 100 or so miles.

i'll try to find a pic and post it up.

 

Sometimes a reverse flush is what's needed when the water p***ages are small enough for some particles to "bridge" and form a dam. A buddy had essentially NO heat in his Dodge Dakota. The heater core flowed, and flowed clear when a garden hose was applied in the normal direction. When the hose was switched to the other pipe a cloud of "stuff" came right out, and he had decent heat this winter. Sure beat replacing the heater core.

 

Start with a radiator flush. You can get it at any auto parts store. Some guys recommend running vinegar for a day or so and then flush and fill. Remember that anything in your radiator is in your engine also. You want to make sure that the heat can transfer from the block to the coolant as well as from the coolant to the radiator. Clean the whole cooling system and not just the radiator.
