Features and Benefits

Radweld is suitable for all cars and mixes with all types of coolant/antifreeze already in the cooling system. You don’t need any special preparation to use Radweld and there’s no need to drain or flush the cooling system.

Radweld also prevents future leaks to help keep your car on the road for longer. By treating areas of corrosion and pitting at the source, the product effectively extends the life of your coolant/antifreeze and individual components within the cooling system, which helps to prevent future leaks while maintaining the efficacy of engine cooling for longer.

Holts develop products for you right here in the UK, based on the ever-changing needs of the car market, so they’re easy to use.

How it Works

Quick and easy to use, Radweld gets to work instantly, circulating through the cooling system to form a permanent and long-lasting repair. Never has it been easier or more convenient to treat and fix problems in your car’s cooling system.

Simply pour and fix, it couldn’t be easier. Radweld then works its way through the system to target radiator leaks without damaging or clogging the system.

No matter where the leak or problem area is within your car’s cooling system, Radweld’s specialist formula will seek out holes, cracks and areas of abrasion, bonding to the material to form a permanent repair. The product is applied directly to the coolant/antifreeze reservoir without the need to flush the system, for complete convenience.
