Where do I add Radweld to my car?
Add Radweld directly into the expansion tank. Make sure the car is cool before you unscrew the cap and top up with coolant antifreeze following the instructions in the vehicle owner’s manual.
Can I use Radweld before an MOT?
Yes. Radweld’s pour and go formula is ideal for a fast repair to your car’s radiator.
If I use Radweld will I have to replace my radiator later?
Radweld permanently fixes leaks without damaging your radiator, so you can simply pour and go and feel confident that your radiator’s repaired. While Radweld has anti-corrosive properties, we can’t guarantee that your radiator will never need replacing, as there could be unrelated problems further down the line.
