If you have a small crack or leak in your engine block, cylinder head gasket, or water pump gasket, you may be able to fix it with Holts Wondarweld, a professional cooling system repair product that seals the damage and restores the integrity of the engine and cooling system. In this article, we will explain what Holts Wondarweld is, how it works, and how to use it safely and effectively.
What is Holts Wondarweld?
Holts Wondarweld is a heavy-duty crack repair product that is designed to fix small holes and cracks in engine blocks, cylinder head gaskets, and water pump gaskets. It is suitable for all engine types, including steel, iron, and aluminium engines. It does not clog or damage the system, and it prevents the need for an expensive engine rebuild. Holts Wondarweld is available in 250 ml and 500 ml bottles . A 250 ml bottle is sufficient for cooling systems up to 8-litre.
How does Holts Wondarweld work?
Holts Wondarweld works by circulating through the cooling system and seeking out small holes, cracks, and leaks to form a permanent repair. It is added directly to the cylinder head outlet, where it bonds with the metal and seals the damage. It is lab-developed to ensure maximum performance and longevity.
How to use Holts Wondarweld?
Before using Holts Wondarweld, you need to drain the cooling system and flush it with Cooling System Flush to remove any residue and contaminants left behind by the old coolant. After draining, reattach the bottom hose. To use Holts Wondarweld, follow these steps:
Remove the top hose from the cylinder head outlet and remove the thermostat.
Use a funnel to pour Holts Wondarweld directly into the cylinder head outlet. Do not pour into oil as this can cause serious engine damage .
Replace the thermostat and top hose.
Refill the system with clean water and run the engine for 15 minutes to repair the leak.
When the repair is complete and no fluid is leaking, drain the system again, flush with clean water, and then top up with a high-quality coolant/antifreeze product.
Note: You must remove the thermostat before using Holts Wondarweld, as it is applied directly to the cylinder head outlet. If you do not remove the thermostat, the product will not reach the damaged area and will not work properly .
