Ford Genuine Ford Fluid VC-1 Premium Cooling System Flush - 22 oz.

Excellent, no complaints!!

Works like a charm

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.

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)

I used this to flush my 2002 Ford F150 that had over 115,000 miles along with the water pump and hoses. It cleaned the system pretty well and i will use it again.

Flush worked as indicated on bottle-good.

After completely draining the cooling system on my 2013 Lincoln MKT, I added this cooling system flush and topped off the system with fresh water. I then ran the engine for about 20 minutes with the front and back seat heater systems 'on' full. Periodically I'd rev the engine to 2500 RPM to increase the system circulation after which I kept the engine running, opened the radiator drain valve and kept a fresh flow of water going into the 'D' gas bottle. Initially the flush water drained with sort of a light brown appearance. I kept the flow of fresh water going until it drained clear from the radiator drain valve. I then completely drained the system again and filled it with Motorcraft Orange 50/50 premix coolant. The entire process went smoothly and the 'D' gas bottle transformed back to its original opaque white appearance thanks to the cleaning ability of this fine Motorcraft Premium Cooling System Flush product.
