Reviews
Holts Speedflush 250ml is rated 4.8 out of 5 by 13.
Rated 5 out of 5 by from Coolant change I used this as a flush for my 19 year old 110k mile bmw. I had only owned the car for a year and had no real history for the coolant so thought it best to flush and fill. Lots of detritus came out. Now all nice and clean with new coolant.

Rated 5 out of 5 by from An excellent flushing product A good product especially in older engines. Follow the instructions for flushing through refilling and draining a couple of times as much more rusty deposits come out on further flushing before an anti-freeze refill.

Rated 5 out of 5 by from A quality cleaner I used this to clean my wife's car's heating matrix. It worked very well and helped flushing out gunk that was blocking it. The car is warm again! A great little bottle indeed!

Rated 5 out of 5 by from Does the job! Had a really awful thick brown sludge in the cooling system but this seems to have cleared it and stopped the overheating problem too.
