AMK® Holts Radweld Radiator Leak Sealer 250ml Stop Cooling System Repair Permanent Seal Fix Antifreeze Compatible Coolant Emergency Automotive Quick Pour Go Vehicle Maintenance

2.8 TDI VW radiator slight leak. Replaced parts and bring still seeping coolant. I used the radweld and the leak stopped. Over a thousand miles driven and still no leak

I was a bit desperate and couldn't afford new bathroom toilet. Tried other stuff but last resort was this. It's has fixed the leak and floorboards have dried out. The inconvenience of changing pipe work and decor would of cost 1ks.The porcelain cistern developed a crack due to Rusty bolts. Try this stuff before you go for the expensive option.regards Del

no more leaks worked perfect

Why did you choose this product over others?: Son had a leak in his van radiator, I thought try this first rather than buy a new radiator. Worked perfectly even took van to garage to do pressure test. Passed no problems

Hubby’s Van thought there was a drip. Used this so far so good

It does help but it's not a long time solution

I use this item for a radiator leak and it worked for a little while and I do mean only a couple of weeks but then stopped working. I would only use this for very short term

Brilliant stuff, fixed a big leak , would highly recommend
