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

I used only half a bottle for my audi a4 2.0 hdi year 2011. Worked as expected, good product.

Cleaned out the system nicely, found some large lumps when i used this and then drained the coolant. I noticed my heating wasn't coming on so used this and now the air heats up nicely.

Worked a treat. Highly recommend. Cleaned out some old rad weld (2 flushes).

It did somewhat cleared my system BUT it foams a lot. It took enormous amout of water to clear it out of my heating system... And Im still somewhat inclined to think residual of product still in the system. So far heating got better so it definitely clears inlet matrix.. however i dont think its powerful enough. It helped in my case so I'll just guve it 4 start but im reality would give 3.5 used on Seat leon mk3 with dual water pump.

Best one of these products I've used. Had oil which had turned to sludge in the coolant system. Had tried other products but didn't get rid of it all. This did. Would buy again

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.

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 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

Reinigungswirkung super. Mindestens 3 mal mit Klarwasser spülen nach der Anwendung sollte befolgt werden. Dann frischer Kühlerfrostschutz einfüllen und korrekt entlüften.

良い商品です

dat dit een goed product is en auto's met km meer onderhoud nodig hebben dan alleen motor olie verversen

Produit réellement efficace. J'ai rincé avec ce produit le circuit de refroidissement du vieux Perkins M 90 de 1989 de mon bateau. J'ai ainsi pu sortir toute la boue qui se forme au fil du temps. Il faut prévoir plusieurs rinçages après utilisation. Pour un circuit de 8 litres, j'ai obtenu 50 litres de liquide boueux avant que le nettoyage soit terminé. Après remplissage le liquide de refroidissement reste propre.
