Pros: quik easy and effective
"My cooling liquid was going down every month or so and i couldn't find where the leak was coming from... Somebody advised me to look for a product similar to this and got over it ... Did what it says on the tin and the leak stopped and the cooling liquid didn't go down since then... Quick easy and effective way to repair the leak"

"My Kawasaki GPX750R had a coolant leak from the seal between the bottom hose and the bottom of the radiator.
I used half a bottle of this Radweld Plus and ran the bike for about 20 mins. The leak is now completely cured and the hose is bone dry when I checked it a few days later.
Excellent, much cheaper and quicker than replacing hoses and clips."

Pros: holts products
"i had a problem with my renault megane the water was going in to the engin block this was going to cost me a fortune to get fixed i was thinking of selling the car and getting a new 1 but then i was told about holts radweld. so i orderd a bottle on halfords website to collect in the morning. when i picked up my life saveing bottle i was shocked at the size i thought to my self there is no way this is going to work. so i opend the cap for the water coolant pored the whole bottle in to the coolant bottle put the lid back on and left the car to run at idel speed for 10 15 min. and low and behold my car is fixed could not get over it. it solved my problem saved me a lot of cash. i would highly offer this product to any one with cillinder head problems thanks for everything holts u sell 1 bottle that dose do wot it says on the tin"

Pros: very impressed
"A canal narrow-boat was giving worrying concern, after overheating. It was using water at the rate of 5-liters every 48 -72 hours.
Before serious and costly investigations were carried out, 3 x tins of Holts Radweld Plus 250mm were added to the system.
The header tank was topped up again 24-hours after the above was added (About 1-liter only).
After a further week of checking, there has been no water loss and the temperature has kept to the specified 70-C
I would highly recommend this product.

"I wasn't entirely convinced that this would fix the massive leak in my Passat radiator, but it did!
I used half the bottle, as directed, and ran the car for twice as long as suggested. The leak slowed, but didn't stop. I continued to drive the car for a couple of days and eventually the leak stopped entirely. It may not be a permanent solution, but will hopefully buy me enough time to put off the repair job until we get some better weather."

This product seemed to have done the trick, although I've only done 200 miles since using it.

Pros: cures your engine troubles, seals leaks or engine problems
Car Make MG ZR
"I dont normally write reviews because of time, but this is an exception. I initially had a problem with my engine & on driving one day the engine overheated and the coolent bottle had blown, the car run dry of all water. I discovered there was leak in the coolant system and possibly the engine had a crack, the head gaskget had not failed at this point. I used Rad Weld to get me out of trouble and after never using a product like this before, it will definately get you out of trouble it has so far cured my problem this stuff is brilliant and would highly reccomend it to get you out of trouble, however i think if the gasket has failed it may not be as effective but any coolant leaks, engine leaks cracks or radiator problems this stuff works trust me im shocked at how good it is - it may not last forver but for now its holding up."

Pros: value for money, easy to use, works quickly and effectively
Car Make Ford KA
"I was having trouble with a leak in my radiator of my Ford KA and was informed by my local garage that I would have to buy a new radiator. It was just before xmas and as money was tight I decided to try 'Holts Radweld Plus 250ml' and see if it made a difference first. I bought the product and poured it into my coolant tank and ran the engine on idle with the heater on for 30mins. Afterwards, I turned the engine off and waited until it had cooled down then I topped up the coolant tank with a mixture of coolant/anti-freeze. I couldn't believe it when I went out the next day as my radiator no longer leaked or overheated at all and buying 'Holts Radweld Plus' had saved me a lot of money from buying a new radiator! I would thorougly recommend buying this product!"

Cons: halfords needs to stock more of this product.
Car Make Ford Puma
"I got this item as a last option after trying to locate a coolant leak, looking for two days, and could not find it. After reading the reviews on halfords I decided to take a chance with this stuff before I went to a garage. I did what it said on the bottle and After the 15mins to this day so far its worked Not a leak insight. I have not topped up for about two - three weeks now, from topping up everyday. So I highly recommend this product if you cant find the leak! 10/10 Its a Chance that worked out for the best!"

"I had a coolant leak on my 1999 1.6 Megané.
I suspected a heater matrix leak as the back window was always misted up inside in winter.
I poured half a bottle of Radweld Plus into the reservoir and left the car on tick-over while I washed it.
I topped up the reservoir and in two weeks the level hasn't moved. Brilliant.

"I bought this to fix a problem with a minute leak from the coolant that was getting into one of the cylinders on my Skoda Fabia, causing a slight discolouration of the spark plug and misfiring on start up from cold. The coolant level was also slowly dropping.
If I hadn't bought this, it would have meant a very expensive cylinder head gasket replacement job. I haven't had a problem with leaking or misfiring since I put it in (3 weeks ago) and it seems to have done the job!"
