    Rated 1 out of 5 by from Just didn’t work I have a very small 0.5 - 1mm hole in my radiator in a mk4 Ford Mondeo, I used radweld and followed the instructions but it didn’t stop the leak. I thought paying the £8 would save me a couple of hundred getting a new rad, but I’ve just wasted £8

    Rated 5 out of 5 by from Job Done: First Time. Had a serious Coolant leak: Losing 5Lts in a week,.. Pouring out underneath the engine. Radwell Plus totally eliminated the leak(s) on the first application, as I ran the engine on idle, as per instructions, outside Halfords. two weeks later, and I haven't lost a drop, nor needed to top up. I'm very impressed.

    Rated 5 out of 5 by from Radwell Plus,.. Did the job, First time. After going thro 5Lts Coolant, in a week, through a substantial leak somewhere underneath the engine, I bought Radwell Plus as a last resort... Any improvement would've been welcome. However,.. bought it in local Halfords,..sat in car park and followed instructions:.. poured into Header Tank,.topped up with coolant, and ran engine on idle 20 minutes,.. and lo, the coolant level had not fallen....and No wet stains seen underneath... Four days later, and I still haven't had to top up the coolant. Nor, have I seen any "tell tale" leak stains on the road. yes,.. I'm very impressed with this product.

    Rated 1 out of 5 by from Wasted my money in this item I wasted money on this item. I now need to spend over £200 on a new radiator. Was hoping it would work as i have recommended radweld to loads and loads of friends / customers / colliegs. I would stay well clear of any radweld product as thay them selves would blaga and say that "maby the hole is too big for this product". Waste of time and money.

    Rated 5 out of 5 by from Highly recommended This stuff ia great!i had a leak in my coolant tank around the raidiator or something so the garage said, the coolant went down completely in arpund 4 weeks which i know its supposed to last ALOT longer than that. the garage said it would cost between 150-250 to get it fixed..which i was saving up to do. But whilst i was looking online at the problem etc i came across this and though no harm in trying although i was a little bit sceptical that something at that price couls fix a £150-£250 problem. BUT i done as it said on the bottle and fingers crossed over 200 miles later ( my son has football games away alot) and over a month the coolant has barelt moved and no more leaking! Im so happy i tried this firsg and save my self a few hundred.
