Prestone Total Cooling System Cleaner - 22 oz., All Vehicles

Worked very well %26 saved me from replacing the radiator. I still don't know what or where the issue was keeping my vehicle from cooling properly. However, this solved the issue completely. I followed the directions precisely; the only deviation was I left it in for approximately 3 days. Bottom line is the stuff worked perfectly!

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.

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.

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.

Excellent value for the price !!!

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!
