i used this stuff an a reasonably clean, always serviced C6 corvette and it got the inside looking like new. After 18 months, I changed the radiator for some resto-mod stuff and when we removed and drained it, it looked like a new radiator inside. Same for the engine block who the engine builder commented on how clean the block was. I remember using extremely toxic radiator cleaners in the 60's that didn't work as well and had to be returned and transported in chemical proof jugs. This stuff shows how R&D works to keep the environment safer and get the job done better. Highly recommended.

Good price. Quality product that works as intended. Cleaned engine cooling system well. Flushed a lot of corrosion and debris from the system. Recommend this product for engine cooling system flush.

Worked pretty good. If your system is really really bad like mine was, i recommend replacing the radiator and other cooling parts.

Used it in my wife's Focus to flush the coolant that was overdue by 50,000 miles.Worked great, prepared the system for the new coolant full.

I used this after my car developed a radiator failure and had added a radiator stop leak. Before adding this Liqui Moly 2051 Radiator Cleaner, I had replaced the radiator, the upper/lower radiator hoses, the thermostats and the housing. I had also used a water hose to flush as much of the radiator stop leak residue from around the engine block as possible. I added this radiator cleaner and topped the radiator with regular tap water. I then ran the car for a few miles, as opposed to run it at idle, because I need it to test the cooling system for leaks and proper operation.It's difficult for me to say that this product worked, since I had replaced most of the cooling system parts, but I can say that after running the car for over two weeks and after several miles, the antifreeze still appears as cleaned as when it was first added. I wouldn't hesitate to use it again if one of my vehicles would require it.

Recien lo utilece para mi Tacoma del año 2000 debido a que le habia notado oxido y sedimentos al hacerle un cambio de termostato, un dia antes utilice otro producto y salio algo de sucio, el Liqui Moly me llego y tambien lo aplique y realmente saco todos los residuos, es muy buen producto

Easy to follow directions, Use this every coolant change to remove any gunk in the cooling system. Easy to read instructions!

My pickup's heater had stopped blowing warm air. As a mechanic I suspected the heater core was clogged. Dreading removing the entire dash assembly to replace the heater core I decided to research coolant system flush products. I found this one to be one of the most trusted by other mechanics. Since it was so affordable I tried it. And to my surprise it worked perfectly and my heater now works without having to do 8hrs of labor. Please understand this does not seal leaks in the system. It is a chemical that dissolves sludge, rust, and calcium deposits in the cooling system.

In my humble opinion, I see it as a good product. I really like it and it works excellently.

Ran this Liqui Moly through the rad and no visible effects we noticed. Did a second flush with Blue Devil and the flush was brown. First time using both and last time Liqui Moly.
