Questions & Answers

Do you think this would work with a dexcool system?

Neither does the study confirm whether it's appropriate for dexcool systems to be used on the bottle Although it is claimed it will flush your system without any problem, I have used it to flush my 2000 Sierra without problems. You should be fine as long as you flush thoroughly with water after you run the cleaner.

Would it be safe to leave a cooling system in place Though I will not drive it myself, I will run it once or twice a week. Flushes are followed by R & R stats. Is that ok?

A "Heavy Duty Clean" calls for leaving the product in for 3 to 6 hours of normal driving over the course of a few This means that it should be driven for one to two hours a day for three Afterward, they say to drain the water. There is no way to know if it will be destructive if it's there for a week, but I have commuted with it in my truck for three days and dumped it and it worked just

Can this be used in nonsilicate radiator fluid vehicles?

The answer to your question is yes!

In order to flush a 6.4 L V8 do I need to buy how many bottles?

You will need to choose your cooling system based on its capacity. A single bottle should be enough for systems with a volume of less than 12 quarts. You will need two bottles over that if your system is over that.

This is a good value for two people
4/5

After buying two containers for nearly the same price I saw this two-pack for almost the same price. So far, I have only used one on a 1996 Jeep Grand Cherokee (ZJ) with a 5. 3L V-8. It takes a 2 liter V8 to flush the system thoroughly. My guess is that it was a success. Over the course of some steep grades last night, I was able to test the rig and it did not overheat. As long as your cooling system is otherwise healthy and your head gaskets are not damaged, I would recommend it.

When I got there, there was a leak
3/5

Plastic bottles seem to be made from the cheapest and most fragile plastic available. The bottles about half full were broken on several places, so there was some radiator cleaner in the box.

It isn't recommended for heavily-weighted individuals Cooling systems that have been contaminated
3/5

My heater core in my 2015 Ford F150 was cleared up by using this product (as per directions too, not just pour it in and expect a miracle). In spite of the fact that it did clean my cooling system to the best of its ability, each flush was clean water, but I still ended up with dirty water. However, eventually, it wasn't able to clean it anymore, and I had to flush out my heater core with a hose because it didn't work. It is worth a shot, well done. It probably won't take much longer than that There may be extreme cases when it works.

Blockage of the heater core was resolved
5/5

I fixed the blocked heater core, and it now produces lots of heat. After following longer forms of instructions twice, a nearly like new Chevy truck went from having almost zero flow to looking just like new. The rinse makes a big difference, so make sure you don't skip it.

You have good stuff here
5/5

You just need to drive for a few hours to get the best results as it cleaned the cooling system well.

The two ways I tried worked for me
3/5

There is some scaling left on my rows, however. The total number of flushes was four.
