Water in radiator rusty looking

How do you clean out a rusty cooling system like the one described above. I'm looking to clean it in the car, not tear down the engine. Thanks

I have not tried this product Thermocure made by evapo-rust but have seen it on tv looks to work excellent. Paul

We used this for a while . Still have 5 or 6 bottles around here somewhere. Works well, but it foams a little in a unpressurized system ..We only used half a bottle per fill

If you have an electric pump on it, drain it including pulling the plugs in the block. Refill with fresh water and a can of some type of cooling system cleaner. Circulate that for awhile and drain again. Circulate and run clean water through it until it runs clean. Refill and include a can of additive. Without block drains and an electric pump, it becomes a little more involved.

I used Justice Brothers products because I sold them and they worked well. Any quality anti-rust product should prevent the coolant from turning to mud.

Could you use CLR safely to clean? I always thought if you drain water and let metal sit exposed to air it would promote rust

You can put about a gallon of cleaning vinegar in the radiator and let it circulate for 5 or so minutes and let it sit over night and then water hose it out then fill the system with fresh water and circulate that for 5 or so minutes and dump it. It will clean out the rust and scale in the block and radiator, you just to flush it ienough to get the water back neutral.

I trailered my old boy's Roadrunner Stocker to a radiator shop when he let it sit over a year with water in it.....They back flushed the system and that seemed to help out.

Although if it was seriously rusted =
I suppose you could blow out a freeze plug that way!
