Radiator flush old diesel engine - Nissan SD33 was Pretty cruddy, coolant had been let go well before I had the vehicle, cooling system had fair bit or rust and corrosion as well as sludge in it. gave it a good hose out, then added 2 bottles of this and ran it for about 40min, heap flor sludge and crud came out after I hosed it again. Seemed to work quite well

Read the reviews before buying and it's true, it froths up like crazy. Yet the back of the bottle says it does not. Had to fill and drain the radiator 5 times to get rid of the froth. Used on a 2004 RAV 4 that had not had coolant changed in the last 10 years, yet I did not see any gunk come out. Either this does not work or the car was perfectly clean.

I was disappointed with the product because it did not seem to clean out all the rust from the radiator, I expected the product to really flush out all the heavy build-up of rust, especially for the price. Just a water flush would have done the same thing.
Absolute rubbish.Wont remove sludge or rust.Red Cordial would work as well as this rubbish.Did as instructed.Sludge still the same.Went to a different shop & bought a better brand.It worked properly & removed all the sludge that SCA brand did not even touch.
Cars cooling system wasn't bad, but it definitely cleaned it out, removed whatever rust was there, only didn't remove the thick grease in the radiator hoses, so I suggest to replace hoses as well when redoing the water pump and thermostat.
Hopeless !!! Do NOT purchase this junk. It caused my radiator froth up like a bubble bath. Took ages of flushing to clear it out. Stay away from this SCA product, stick to standard well known brands. Do not buy !!
Not too bad. It flush out most of the stuff. Some minor leak on my car (believe my car was not seal properly, in previous).
I had a lot of rust in the system from the old radiator and this Flush cleaned it up nicely. I used this after draining the system a couple of times and installing a new radiator.
It is radiator flush, i don't see any cloudy rust bits in my coolant anymore.
