Topic: 36' rusty radiator fluid


Buckd44    -- 10-17-2015 @ 6:04 AM
  Going through the 1936 Ford I inherited, I drained the radiator, found it was pretty rusted fluid in it. What are recommended steps to flush and remove most rust before adding new coolent.
Thanks,
Nate

  First, I would drain out all the old coolant, making sure the heater valve is open,if any, Remove the thermostats,probably in the upper hoses, hook hoses up again, and run water through the radiator until it comes out clean.Then get a good brand of cooling system flush and run it through the system according to instructions. Then replace thermostats and refill with 50/50 antifreeze. If after all this you have overheating problems, the radiator will need to go to a radiator shop to cleaned and/or rodded out.

  drain completely out, remove thermostats flush with fresh water, drain and refill with cheap white vinegar ( about 3 gallons) run this thru about 3 heat/cool cycles, drain out, flush again, run a box of baking soda/water mixture, flush out the refill with 50/50 mixture water/antifreeze and add a bottle of water wetter to this mixture. go to grocery store 1 gallon of vinegar is around 3 dollars--0best flush out for hardly any money

  Is there a thermostat in a 36?

You mention using about 3 gallons of white vinegar. Isn't the capacity around 5 gallons? Or am I remembering it incorrectly?

  5 gallons is about right.
