I doubt they’ll wanna print this review. I’m a 40yr Plus mechanic n don’t usually take short cuts, but in an emergency I had a water leak 363 miles away from home in my Vauxhall Astra 8v Car, these are favourite for 2 faults ! ( Waterpump n Head Gaskets ) so I looked n Yep, the Waterpump was leaking ! I used Engine Coolant Sealer, which got me home slowly but surely. I drained it the day after n power flushed it n ordered a new Waterpump Assembly n Timing Belt n fitted it 4 days later. Changed the Stat ( which was blocked ) n finally took it for a spin ! As it was Summer I didn’t use the Heater, come Winter, No heater ! Bought 2 bottles of MANNOL n flushed it through for Over 2 Hours ! Ran the heater n Nothing ! Cold Air ! Pressure Tested everything ( perfect ) Unfortunately this stuff doesn’t always work ! Tried it again n same result ! Heater Matrix is clogged up ! “ wear gloves ! This stuff burns “ it’ll clear rust deposits from a radiator ! It’ll clean up the internals in a coolant system of non antifreeze use ! BUT it is Ineffective against a Blocked Heater Matrix ! 😞Read full review
