LIQUI MOLY Radiator Cleaner | 300 ml | Cooler additive | SKU: 1804

Great cleaner...the amount of nastiness that came out of the coolant system was atrocious

I mean buying this brand I expect pretty decent performance and it worked well pretty decent value for money with the amount you can make out of the 2 cans and following the instructions it's easy to use

I use LIQUI MOLY Radiator Cleaner and it works great. It removes dirt and rust from the cooling system without damaging any parts. The engine runs smoother, and the temperature stays stable. It's easy to use and effective, but the price is a bit on the higher side. Still, I recommend it.

This might not be the cheapest engine water flush on the market but it certainly does a decent job of cleaning the water ways.I'd already flushed my engine a week before and got out plenty of dirty water, but as the vehicle spent that last decade in a shed til recently, I thought I'd give it good clean through.Put this in and warmed engine for 30mins then left for 2 days, took it for a 20mile drive, came back and undone the top small hose... and hey presto - Gravy... took a good 15/20mins flushing it and blasting the radiator through the cap... now nice and clear.Great product, happy to use again on my next vehicle

I used this for a clogged heater core after teplacing the thermostat and see that my system doesnt have any rust as I change coolant every 2 years. Few sand like bits came out but it did not unclogged the heater and no heat was comming out. Then I used prestone flush from the heater core pipe and let it sit. At first it made it worse. Then after an hour the return line started warming up and there was heating in the cabin. I left this for one hour and the prestone for multiple hours running at operational temp. I dont write many reviews but I thought this is useful. I am goibg to qrite a review for the prestone as well.

Cleaned out my radiator and engine just fine

great service

Easy to use and does the job well.Used before on different cars, will use again, recommended once a year during service to remove the gunk and start fresh.
