Ease Of Use

Its a cleaner and lots of brown water came out so I assume it cleaned deep into the system. That said, the bottle says run the engine and flush once more after draining the cleaner...I would suggest two system refills and draining. Be prepared for some effort.

Coolant Total System Cleaning and Flush

walmart.com

Np, So far... If you still have bubbles. Have to flush the radiator 2 more times with distile water.
Poor half into two my Toyota's car and it cleans pretty well overall. And it solve a squeaky noise with one of my Toyota water pump.

Np, So far so good

Having engine cooling issues. Had a little build up in a 9-year-old radiator. Cleaned things up. Turned out it wasn't the problem, but at least I know the system is clean.

Does what it should

After draining the radiator and water flushing the entire cooling system, including the heating core once, I removed the thermostat  I added the Flush cleaner and water til full, started the car and and water as it went down, keeping the reervoir open. Once it stopped going down, I just let the car run until it was up to temp., then I rased the RPM up to 1,200 for a couple of minutes, shut the engine down then carefully drained the raidiator again with the reservoir open. once that stopped, i left radiator drain open, filled the reservoir, started the engine with heat on full and kept adding water until it was draining out quite clear. Shut the engine off and let the radiator drain out again. This product worked great with one application ! BTW the car has 93,000 miles on it.

I normally don't write reviews for such mundane products but this stuff works.  It's good from 10 minutes to 3 hours of cleaning.  The best part is there's no need to drive your car for 3 hours.  It can remain in the radiator for up to two weeks so you can do your normal commuting.

It worked for my classic car.

[This review was collected as part of a promotion.] Excellent cooling system cleaner. Simple to use, exceptional results!
1- Important drain all the old coolant.
2- flush the radiator with clean water 
3- add the prestone total to your radiator fill with water and run engine for 10 minutes for best results leave in for a total of 4 driving hours.
4- drain and flush the radiator with clean water.
5- fill with prestone or your favorite coolant.

Simple to use, excellent results

[This review was collected as part of a promotion.] Preston's DEX COOL is required for use in my Firebird.  Product had immediately availability. The product is superior in quality and performance.

[This review was collected as part of a promotion.] Cheaper than AutoZone

[This review was collected as part of a promotion.] cleaned better than anything i have used in the past.
i was actually astonished that it single handed stopped the engine from overheating.  i refilled with a 50/50 mix %26 haven't had an overheat since.

Marvelous stuff

for the price yeah it works good but it don't clean as good as what it used to years ago but for light flushing and considering the process of it yeah I recommend it probably it just depends if it's not too gummed up yeah this will work good if it's really bad I would go more for a heavy duty radiator cleaner I didn't think it cleaned that much now the priest Stone from years ago it was half the size bottle and it really cleaned everything out

light duty cleaning
