Believe it or not I have a friend who adds Lestoil to the coolant to clean his radiators and he swears by it. Says its real safe on them also. He gets the system hot after adding it then drains and flushes with water then replaces the coolant.

Exclamation Re: OT:?? old radiator cleaning solutions

Old cooling system material: Flush system with water and drain. Add 3 or 4 -2 Litre bottles of COCA COLA. Fill balance with water and run for 4 Hrs. Drain and flush with water. Fill system with water, and run 15 minutes, then drain. Fill with coolant, and you should be good! The oxalic acid and sugar in the coke will clean the radiator, without doing damage to the core.
If you have heavy calcium deposits, vinegar - full strength all the way will probably clean it out BUT: you must neutralize the acidic solution after using it. Drain the radiator, and flush with water. Drain again and fill the system fully with vinegar. Run until hot, and then vary speed from idle to full speed for 2 hours. Let cool 1/2 hour. Restart and run speed up and down to thoroughly agitate solution. Immediately drain solution, and flush system with water. Fill system with water, run speed up and down for several minutes and drain. Mix 1 pound Baking Soda in 2 gallons of water. Fill radiator and cooling system, and run for 15 minutes. Drain system and flush with water. Fill with water, and run another 5 minutes. Drain and refill with coolant. I would suggest adding a water pump lubricant for the first coolant filling, as the vinegar probably will wash off any lubrication on the shaft. Failure to neutralize the vinegar may lead to heavy rusting of all cast iron parts, and possible galvanic (battery) action between the brass and iron parts of the cooling system. Once neutralized, after all this, you should be good to go. If the system continues to over heat, check the thermostat if the machine has one. If not, then the radiator core probably has to be 'rodded', a process where the top of the tank is removed, and the individual tubes are reamed out with a small rod. If this is a honeycomb core, then the radiator will probably have to be dipped. This may lead to leaks in the core. Unfortunately, honeycomb cores are difficult to clean effectively, due to their construction.

Lightbulb Re: OT:?? old radiator cleaning solutions

Just a note,many in line flathead engines have a water distrubation tube behind water pump that directs coolent toward valve seats. The small holes in tube become blocked and no matter what you do, engine runs hot. if you're lucky the tube will pull out and you can clean tube,if not replacement is only solution.Steve

Just baking soda and clean water works well. Drain the system and fill with water, add a box of Arm and Hammer and run awhile , has worked good for me.

Be aware that Coke and vinegar are acids. They work well to remove calcium(lime) buildup, but will react with metal. Don't make a concentrated solution.....more is NOT better, don't keep in for long periods of time and flush the system well.
