back to the idea,plug the lower rad hose,put the plug back,mix lime a way with water,dump it in the rad elbow leave it a few hours n maybe repeat,will the headgasket,water pump, be safe?wa was planing to replace the water pump anyways,any advise will be help full plus if it works it ll be better for the cooling system rad,w /pump,engine,us,please reply with ur thoughts,

I know that you can remove rust from a gas tank if you use a few volts DC and a anode for the rust to collect on. Have used it on motorcycle gas tanks many times-even a low powered battery charger works

The Home Depot carries Zep Metal Prep Dip Rust Remover. It's a chelating agent which will not harm the base metal. Lime Away is almost entirely phosphoric acid which is pretty benign so long as you neutralize it by flushing with water and baking soda after draining the Lime Away. Got a pH test kit? If you have as much sediment in your cooling system as you indicate you'll probably want to pull all the core plugs and use a pressure washer to clean the water jacket.

I poured a gallon of the Zep Metal Prep into my '67 Valiant's cooling system and drove around. I left the solution in the cooling system for about a week. The rust turns from orange to black. I pulled a core plug after using the Zep and found the water jacket to be very clean. Maybe I should have pulled the core plug to see before and after, but I didn't.

An old steel shim head gasket might not like the Lime Away. I'm specifically concerned about the gasket rotting through where it covers the water jacket hole at the front of the block. If that hole is open coolant will short circuit the block and head. Composite gaskets like the FelPro should be fine. If the head has been off in the last 20-30 years it's likely to have a composite gasket.

Preston Super Radiator Cleaner is citric acid (sodium citrate) in water and the pH is only 8.3-9.9. http://www.setonresourcecenter.com/msds ... leaner.pdf

The MSDS for Lime-Away doesn't give the pH and is going to be harder on iron than the Zep Metal Prep Rust Dip. http://www.ritekem.com/msds/nsn%206850-01-359-9214.pdf I found an older MSDS for Lime-Away and it lists 27% phosphoric acid. http://www.rsu19.org/assets/files/safet ... %20Way.pdf

How does an acid have a pH greater than 7.0 ?

LOL! I wonder if that's a typo or what. Can hardly believe I missed that especially as I typed it out.
