Name: Holts Radweld Plus 250ml
Manufacturer’s Code: RW2RGA
How to use:
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 Plus, shake the bottle thoroughly to ensure that the contents are well-mixed.
With the engine turned off, pour the appropriate amount of Radweld Plus 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 Plus, 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 Plus 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 Plus has effectively sealed the leak. It may take some time for the sealant to fully take effect.
SDS InformationNo, this should not be attempted under any circumstances.
No as the product is insoluble in oil. This could cause the formation of a jelly and potentially block your engine. If the product is accidentally poured into the oil, the vehicle needs to be drained of oil immediately without switching the vehicle on, before flushing through the system multiple times and refilling with fresh oil. It would also be advisable to get the vehicle to a mechanic without running it.
If a seal has not occurred after using Radweld you should never add a second dose or bottle. This can cause blockages in the system. As per the above, if the product has not sealed the leak, then the leak is too large to repair.
Yes
The product has not been tested for these uses so it may block certain channels.
If used at the correct dosage, Radweld Plus cannot harm any part of the vehicles cooling system, including the heater matrix. This can only occur through overdosing the product or not flushing the cooling system properly prior to adding the product. This can be removed by a mechanic if they backflush the cooling system.
There are several differences between the 2 products, Holts Radweld Plus and Holts SEALit. Firstly, they have been developed for slightly different markets, with Holts Radweld Plus aimed at retail customers who can use the product at home, whereas Holts SEALit is for the professional retail channel. However, the formulations are significantly different, with Holts SEALit being the latest development in Holts cooling system repair product portfolio. Holts SEALit has been developed to provide a permanent repair to the cooling system.
Radweld is designed to seal leaks in radiator hoses and the radiator itself. Radweld Plus was the result of a project to improve standard Radweld. By improving the formulation it’s able to seal a wider variety of leaks, such as leaks in the engine block and cylinder heads, which standard Radweld cannot seal.
An entire bottle of Radweld Plus treats cooling systems up to 21L in size. If your vehicle has a cooling system capacity of 7L or less, then only half a bottle should be used.
