Works well and at a very good price through toolstation, cheaper than other shops and without waiting around. I bought it through their website and paid, within a few minutes I received a message to say it was ready for collection. Great service and highly recommend. ThankYou.

Holts Speedflush vehicle radiator cleaner is much reccommended as being superior than just using water alone to flush out contaminants and rust from the radiator.

I was told my radiator was completely blocked by a "radiator repairer" cost to fix,£380 !!!
Guess what, thought I'd decline his decline his generous offer and have a bash myself.
Bought this, popped in with some boiled water left for 24 hours with the occasional jiggle, flushed out with clean water. Result. The inside as far as I can see look like new, no signs of corrosion or limescale and water flows totally uninhibited.
Marvelous !

Good product really pleased

Brought for my motorbike, seemed to pull some brown much up and out the cooling system even after multiple flushes before hand so I’d say it works

Straight forward when added to coolant replacement procedure

Very easy to use - done as an extra flush while replacing coolant on my Land Rover which can be tricky to remove the whole coolant volume - very straight forward (after reading the instructions on the Holts website) - note dilution happens in the radiator itself - amazing what comes out when you drain it - worth a check for any leaks in the radiator/coolant system prior to use as you would before coolant replacement
