Ist bottle!
This seems to be working! I have only had it in my Jeep for a few days, but it is cleaning out the engine block and cooling system!

    radiator flush
    Not sure how well this worked as many people did liked it. You can use vinegar diluted with water and maybe get the same results based on YouTube video

    This stuff knocks rust loose like nobody's business. Add this product, drive around for a while, and flush it out. I had to treat my car twice. My car's coolant is now a bright, translucent green. Heat is good, and running temp is perfect.

    Performed the 3-day deep cleanse process, back flushed heater core, and filled entire system with fresh coolant and have good hot heat again. Do not know which of the three steps solved my problem but the flush and cleanser must get some credit if not all the credit.

    Best radiator flush I have found.
    This product works great. I have an older car (1993). The radiator had rust and "gummy" like stuff floating around inside and under the radiator cap. One bottle in for a couple days and drained. Then another bottle for couple of days, then drain again. I was amazed. Be sure to use distilled water with your recomended antifreeze when you fill the radiator after the above proceedure. If your radiator isn't too clogged, 1 bottle will work good also. I have used this product before on a newer car. Truly a money saving product that will actually flush your radiator.

    excellent product
    my 2001 Expedition would not put out any heat in the front. Back one worked. I used 2 bottles and drove it for a couple of days now it is blowing such hot heat it'll burn you up. it cleaned out my heater core. Excellent excellent product
