Marc L: This stuff is very impressive. Would use again. Used on my 2002 F450 7.3 when switching from green to red ELC.

Mark A.: When your coolant fails a nitrite test, this product works perfectly.

Rock: Just so you know, it comes in a quart bottle, not the 22 oz bottle shown in the picture (Actually this way you get 32 oz. instead of 22 oz.)
I was changing my coolant on my pre-owned car over from the orange coolant to the new Ford spec'd Motorcraft Yellow. The original coolant was extremely clean (60k miles) which leads me to believe it had been flushed before by someone or some shop. Anyways it was orange something and I replaced it with Ford Yellow per spec.
I can't say it did much of anything in my case just because after draining the orange it all looked extremely clean so chances are the internals were already in good shape. It does foam up a little bit so there is some sort of detergent in it. I've seen old coolant in years past in some cars that came out rusty looking. This looked nothing like that.
I'm glad I did it as it is the correct way to flush the system. I also used distilled water as a final flush and as part of the final fill. (2015 Ford Escape 2.0l EB)

Lenny: Someone in the past used some type of stop leak to avoid changing the intake manifold. I've flushed with water before but it never seemed to come out 100%. There were never any overheating issues, but I knew that system wasn't fully clean. I drained the coolant, added the product, filled with water, drove 50 miles. Then I flushed all parts of the cooling system and LOTS of stuff came out (this is a 190K car that otherwise runs great). I ran it twice with distilled water, drained, and added back anti-freeze. I notice now heat is much hotter AND coolant is very clean with no particles and green like it was when new (always use the right GREEN coolant, not yellow universal). My degas bottle has a bit of buildup inside, it is very difficult to clean because of internal baffles. I thought of replacing it but it is more cosmetic than functional. I may try this product in the bottle next time with full concentration, swish around, then add to the system.
