Prestone Radiator Flush and Cleaner is a 2-in-1 formula designed for light flushing and heavy-duty cleaning for cooling systems to help prevent overheating, the #1 cause of engine failure. This premium formulation is designed to remove heavy rust and scale deposits in neglected cooling systems. These deposits can dramatically restrict coolant flow and reduce heat transfer, which may lead to possible overheating, breakdown, or costly repair. A super-chelating additive effectively removes heavy deposits by drawing metal oxides into the solution. Though strong enough to help restore maximum cooling system efficiency, this non-toxic, non-acidic product is easy-to-use and safe for all cooling system metals.

Always Flush Coolant System when you change coolant. Always.
You can’t use CLR in a modern engine. But you can use Prestone Flush on the Super Flush instructions. I never do the short instructions. Usually I water flush it (not during winter, i’d leave Anti Freeze in with this) before I use this flush with water extended time frame. I’m telling you so much junk will fall out of your motor you won’t know what to think. It works great!I got this because I did a head gasket on a 2.0L DOHC with plugged water port on the head/block in one spot, so you could imagine how Crusty the coolant system looks. I flushed everything but the block already and will use Prestone Flush just like I have before with other cars to make sure it does not replug the system. Up to $1,200 to have a shop do all that, and I don’t intend to repair this ever again. So you know, do it right. Flush the system. Better heat transfer, is a hotter heater in winter time, less problems otherwise.

Great product, slow shipment
This is a great radiator flush but don’t order from this vendor if you need it right away. It didn’t ship for two weeks and I had to cancel 3 appointments to get my cooling systems refreshed.

Good to use more often than I do
A wise man once said to me “get a good vehicle and KEEP it”. They don’t use salt on the roads in winter where he lived and I’ll always remember the truck and wagon he drove were born the same year as me. Back when silly manufacturers allowed you to work on your own things. As much as manufacturer’s are trying to keep you from fixing things you own or even owning the things you own, there are plenty of things you can still maintain to keep the cost of ownership to a minimum. And no matter what anyone pressures you into thinking, generally, the “greener” option is to keep your old ‘whatever’ running for another year, if you can do so safely. My vehicles are old and I’m proud to maintain them myself.I don’t know if this stuff is formulated to look so gross when you flush it out or I was just really overdue. I ran 3 bottles with distilled water in-between and it got better each time, but comes a time to get it dirty. Hopefully I didn’t knock the rust holding everything together out of place.

Saved a $1,500 repair of the heater core which was plugged with sediment and quit working.
Very easy to use. Amazing results! Heat system never worked this good. Overall cost , about twelve dollars!

Damaged water pump seal
This stuff caused my water pump seal to start leaking. It happend after I flushed and added final mix 50/50 Preston . I now have a leak from the weap hole on the water pump. This stuff did something to the shaft seal so now I have a small leak. Have to replace water pump to fix. On my car that is going to be money thing. My system was so clean that when I ran the flush there was no color change so if you drain several times with distilled water and get it very clear don’t use this stuff. Jus add final mix.

Worked good
The cooling system on my â05 Silverado was not bad. The anti freeze was not rusty colored but it was eight years old. So I flushed it all total 4 times with distilled water(12 gallons). I absolutely do not put faucet water in any of my vehicles cooling systems. I keep my vehicles for many years so it is vital to keep minerals out of the cooling systems. That folks is from my experience of 60+ years of driving and caring for my means of transportation. I am 77 years young!

The flush and clean worked well,should have shopped around for price overpaid for product. Convenience has a price with it. Took a while to get

My radiator had relatively clean coolant when I drained it, a couple of particles sure, then I filled with this cleaner and fresh deionised demineralised water, ran for 20 mins and oh my it was brown, so I drained again and repeated the process but left it in for 6 or there about a hours of driving, well super clean result it dislodged everything. I then refilled with water again dropped the bottom hose out and removed the thermostat and replaced with new and connected everything again, filled up with coolant as per spec and drive ensuring all air pockets were gone, took another small sample from the drain and itâs spotless coolant. I didnât expect to go so far with it but when I saw the progress I had to keep going simply because of the way this works. Very impressed.

ONE OF THE BEST COOLANT CLEANER THAT I HAVE EVER USED, A REMINDER IT’S BETTER BEFORE YOU GET YOUR COOLANT FLUSH, TO DRIVE YOUR VEHICLE WITH THE ADDITIVE IN THE COOLANT FOR AT LEAST 6 HOURS. PLEASE READ LABEL.

I used this to flush out my Jeep GC Limited. Work an absolute treat and was able to put in new radiator fluid. Would purchase again!
