    Rated 5 out of 5 by from Easy solution to an annoying problem Does precisely what it says on the bottle. Quick and easy fix for a small leak in radiator. No experience of how long this might last however. Wise to regard it as a temporary fix until circumstances allow replacement of radiator for a long term solution.

    Rated 5 out of 5 by from Does what it promises Works well and exactly as described. You will need a funnel if you don't have an in-circuit water overflow tank (only one pipe) as it has to go straight in the radiator, but has so far lasted 3 months in fixing a very small leak in the radiator. I will still need a new radiator at some point but spending a few quid on this has put that off for a good time, and it was a quick easy fix.

    Rated 5 out of 5 by from Good for a temporary fix if your car is needed. Good for a temporary fix if your car is needed for driving before getting a full on fix. I own a range rover and noticed coolant light come on and over 2 days i lost around 5-7 liters of coolant. my local garage was not able to take the car in to find issue and fix for two weeks and with me needing to drive the car daily there was no way i can put the car of the road for 2 weeks. so i after some research online, though i would give this a try as a temporary before getting the car into the garage. Note this is a silver thick liquid and seals cracks in metal parts or seals. it wont fix broken pipes. also don't use more then one bottle as it will damage or clog your vehicle and on small cars only use half bottle. I will be getting the garage to flush the coolant system when its fixed. but it currently holding the leak and letting me use the car again. so worth £6 ! hope this helps some people out there.
