Used this product to do a full flush of a somewhat neglected cooling system. Seems to have got small black beads (rust pieces?) out but there are a couple of gotchas that you should be aware of.
1. You will need to rinse with water at least three times after you drain this flush product from the cars radiator. Otherwise, white foamy residue will remain which- not clear to me- is okay to retain in the radiator long-term.
2. If there are weak components in your cars cooling system, they will fail- my car's heater bypass hose developed a leak almost immediately after I used the product. I am not blaming the product - if anything it may have accelerated failure of a marginal component. But I mention it here since potential for such failure exists with this product.

This flush removed all the deposits I saw in the coolant hoses prior to running it through. I had tried running a 20% citric acid solution prior and it didn't get nearly as much out as this product did.

Only issue is that it is foamy. I needed to flush my system with water 3 times before it would no longer foam.

I couldn't find the "Super" Gunk cleaner in the stores and I was reluctant to pay $5 shipping on a $5 product, but I'm glad that I did. All kinds of junk was flushed from my 23 year-old radiator. I don't know how this compares to the non-Super flavor of this radiator flush, but no matter - I'm very happy with the results. Frankly, no Gunk product has disappointed or let me down yet!

I used it to clean my 1998 firebird. My car got muddy coolant in it. I paid to ask the store to replace the coolant and thought that it would become clean. But, I was still muddy after the coolant was reaplaced. I used two bottles of Gunk C2124 and my coolant keeps clean now.

I used this to flush my car's coolant system. (And to be honest, I had neglected it a bit.) It seemed to work well. Product description reads that it is safe for aluminum engines / cooling systems.

I think it did what it was supposed to do. The coolant in my taurus was brown and murky and the heater core was becoming clogged. the new coolant is staying clean looking and the heater works better now.

Definitely cleans out some gunk, but left behind quite a bit in my crud coated system. There are limits to what this product can clean out and I was hoping for a little more.

I'm pretty sure this worked well. It's hard to say for sure, but after running it through my cooling system, and then back-flushing it, the heater core was unplugged and the heat started flowing again.
