    Rated 5 out of 5 by from Holts Radweld + The one that does a real repair not a bodge! Buy Holts Radweld+ It is well worth a couple of pounds extra to get this (Gold Bottle) over the standard product (blue bottle) or the foreign competitors, why because this actually is a repair rather than a temporary fix. I have used others in the past without much long term success so was not confident that this would work. The problem a heater matrix spraying hot steaming water all over drivers footwell in large amounts. Pretty dangerous to drive at all like this. Normal repair is to remove all of car dashboard and fit new heater matrix. Very difficult and time consuming = very expensive. So decided to try this. It worked and no more leaks at all. Nothing lost from cooling system after a month. Like all British products it does what it says it does. Just Great. This is safe to use, it does not clog up your engine, like some other heavy duty sealers.

    Rated 5 out of 5 by from Fixed head gasket leak Great product, local garage quoted 550 and keeping car for a week! Not good if you need it everyday for work. My head gasket was not fully blown I think, detected early - was losing coolant at a rate of a full tank going in about a week in my 1.4L Vauxhall Corsa. Followed instructions on the bottle and no problems so far, have drove thousands miles since using.

    Rated 5 out of 5 by from Head gasket repair I own a Vauxhall Omega estate. Radiator recently failed. Garage replaced radiator but when the radiator broke the head gasket failed. 2 bottles of radweld+ seem to have fixed problem. However long it lasts, it has saved on £500 of engine rebuild. 2 bottles needed but deffinately recommended however long it lasts.

    Rated 5 out of 5 by from 1300km and no leaking Hi. After 1300km I noticed that there is no leaks. My coolant level is on the same location. Before it was dropped down from "max" to "low" after 600km when driving.

    Rated 5 out of 5 by from Great Product I bought this for my granddaughter's car. She hasn't passed her test yet (18 years of age) but drives everywhere with my daughter (passed test) in the passenger seat. After the radiator had leaked a couple of times I decided to buy Radweld. My husband put it in the car's radiator and we kept our fingers crossed. Brilliant product, the radiator hasn't leaked since.

    Rated 4 out of 5 by from Great product I used it to stop the Ford Fiesta 2006 radiator leakage which was quite intense. It did stop it as expected although the instructions were not quite clear so I just poured it into the overflow container and kept the engine running for a while. The next day the leakage was gone. Great price/value !!!
