Cooling System Cleaning Kit

I purchased the Radiator and Block Cleaning Kit along with the Seal Expander earlier this year and wanted to share my experience.

I tackled the radiator clean over the weekend, which ended up taking a few days in total. For Part A, I followed your video’s advice and used a sock as a filter (as shown in the attached image). I also used a sock for Part B, though I don’t have a picture of that one. Both caught a lot of debris, with the sock from Part B being particularly grimy! I’ve also attached a few images of the water from Part B for reference. I think I drained it about 7 or 8 times altogether. And as you can see it progressively became cleaner.

In addition to the cleaning, I replaced the radiator hoses and thermostat, which were long overdue. They hadn’t been changed since I got the car in 1998!

The car is now running great. I took it for a short drive after the clean, and everything seemed fine. I’m planning a longer trip to visit my mum in Laurieton this Christmas, which will be the real test, but I’m confident the cooling system will be much more efficient now given the amount of gunk I cleared out.

I also added some of the 230 Seal Expander to the power steering unit and will monitor its performance.

It’s now a few weeks later and I’m happy to report that my 1997 Commodore is likely running better now than it did when it was new. During a recent trip, it handled a substantial load over several days in high ambient temperatures, and the temperature gauge stayed in the lower third throughout. I couldn’t be more pleased with the results!

I’ve already shared your details with several people and will continue to do so. Thanks again for such excellent products!

He had an ongoing overheating problem and talked it through with Peter before using the 239 kit; his sock filters caught iron salts, rust and sludge over two days of flushing.

on using the kit provided I was concerned when I saw a yellow film starting to form in the top tank of the radiator and the inline filter in the top radiator hose regardless I proceeded as described on the part a can for the 7 days recommended I then flushed the system this did take some time about 10 fills of the system including running the motor to ensure all of the part A was flushed out I then added the part B ad described and let stand for 16 hours at this time it had converted the yellow film this I then flushed out it also took about 10 refills of the cooling system and running the engine to operating temp to flush the inspection of the top tank and in line filter were as described free of any sign of yellow film or rust build up and clean of any dirt

I am satisfied with the product and will be telling others of the product that it does work and will clean your classic car and will not damage you pride and joy while doing its job this product has stopped me from having to remove the engine and caustic washing the block and rebuilding the engine to resolving the water core rust scale problem I had in the block thank your again for your help I will now be looking for something to restore my diff pinion seal and engine crank main seal and timing cover seals on my ford 9″diff and 289 ford small block engine

I recently purchased and used your product the 239 Liquid Intelligence engine cleaning kit. I have a sailing yacht with a small auxiliary diesel engine which is cooled directly by seawater (after filtering).

For a long time I have been trying to fix an intermittent cooling problem with no success. I had replaced the thermostat, sensor and exhaust mixing elbow with no success.

So I researched a bit on Google and found your product. I mixed it in a plastic rubbish bin and recirculated it through the engine for a bout half an hour. I then left it to stand for a week , recirculated it again and then flushed the engine with Part B of the kit . After that I flushed the engine and ran seawater through as per normal. I’m happy to inform you that the problem is solved and thank you very much!!

Just a thank you message for the tech support on Liquid Intelligence I am always sceptical on claims made about products, but wow I am now converted, I could not believe how much rubbish was removed from my cooling system, if anything it’s probably too cool know. This job was a legacy of the previous owner who rebuilt the motor without acid dipping it before the rebuild Thank you for the customer service and a great product. Your seven day a week tech support was particularly appreciated.

“I used your Liquid Intelligence 239 kit and it now shows well under half on the temp gauge scale in the same running conditions.”

I want you to know that your product has worked a treat on my 1974 Triumph 2500 TC.

I recently bought this car which is low mileage but 46 years old. Only 40,000km but has been kept in the shed for most of its life.

It ran hot and would go to extremely hot when in slow traffic. I used your Liquid Intelligence 239 kit and it now shows well under half on the temp gauge scale in the same running conditions. I was about to remove the radiator, and have it cleaned or replaced but was encouraged to try this product by a local engine restoration person (whom hasn’t used the product but has seen it on line). His theory was to at least clean the engine out first and so determine if the radiator alone is the cause. Obviously, this product works well.

His 46-year-old engine had rust scale on the water jacket walls and ran hot in traffic before the clean.

Here we are at Eastern Creek with “Dame Edna” going out for the parade laps. After using your radiator and block cleaner my 1934 Humber runs 15 degrees colder. I now spend more time watching the road and less watching the gauge and worrying.

Helen sent the email with a photo of her Humber heading out for parade laps at Eastern Creek.
