Holts Radweld Leak Repair Instructions

Radweld is proven to seal small holes, cracks and fissures from within the cooling system, providing a permanent repair for a fraction of the price of replacement parts.

How to use Radweld:

Ensure that the vehicle’s engine is cool before starting the repair process. Park the vehicle in a safe and well-ventilated area.

Before using Holts Radweld, shake the bottle thoroughly to ensure that the contents are well-mixed.

With the engine turned off, pour the appropriate amount of Radweld directly into the radiator or coolant reservoir. Refer to the product label for the recommended dosage based on the system’s capacity.

After adding Radweld, top up the cooling system with the appropriate type of coolant to the recommended level. Ensure that the radiator or coolant reservoir is filled to the specified capacity.

Start the engine and let it run for approximately 10-15 minutes to allow the Radweld to circulate through the cooling system and reach the leak.

After running the engine, monitor the cooling system for any signs of leaks. Keep an eye on the previously identified leak site to see if the Radweld has effectively sealed the leak. It may take some time for the sealant to fully take effect.

This product WORKS. Had a leak in my system and one treatment of this fixed it. I’m talking it would leak a full reservoir full of water on a short 25 minute drive. No leaks at all after one treatment. Brilliant stuff 👍

I found it on a gas station when I needed an emergency fix I give it a try it worked it even holds the 105*C coolant temp the bmw engines get up to when at low load, so now I can use the car until the new radiator has arrived.

I’m getting some for my car but this video isn’t helpful... do we pour it in and fill to the up with the current coolant in there or no?

What are the chances of this clogging the channel's in radiator?

Don’t go by the advert I looked on the instructions and it said not to mix with coolant or anti freeze and suggested also removing shark plugs sounds more complicated than this nice advert

I've just bought a car with chemweld in the radiatior and heater system. It is holding water well, I didn't know about this repair until last week, when my mechanic serviced my car. I live in the South Australian outback and have driven it long distance and in hot conditions, it's just fine. I've had the cabin filters replaced with the service. With the a/c running it's fine but with three heater running it has a obnoxious odour, is this from the chemweld in your experience?

This isn't an instruction. It's an advert.

Do we pour this into the same place as where we put the coolant? I have a coolant leak in my bmw. Also, I also have an oil leak, do I pour this in the same place that I would ordinarily oil?
